1 Automated vulnerability detection and prevention reporting of php-based web applications using PVRS and comparison between PVRS & RIPS
Santosh Naidu, Subba Raju KV

Abstract —Most of the web servers support some sort of scripting environment today to deploy dynamic web applications. PHP is a general-purpose server-side scripting language for creating dynamic webpages. Most people learn PHP syntax quite quickly and within short period of time they were able to write a script that works using mainly through online tutorials, references and books. The major problem is that most of the people forget the security aspect of PHP that one must consider while writing PHP based applications. Also mentioned are the common programming mistakes done by developers when building PHP web applications and necessary means to protect against such vulnerabilities. Presented are the most common PHP web application vulnerabilities and the necessary mechanisms required to compose secure code by leveraging PHP’s unique features. So the paper here finally discusses about the tool PVRS which was specially developed for vulnerability detection of php-based web applications and also discusses in brief about the vulnerabilities that are mentioned in the tool and finally compares PVRS tool analysis results with the existing tool RIPS.

2 Deadline Perception with Enhanced Dynamic Multilevel Priority Scheduling Scheme for Wireless Sensor Networks
Amulya P, Subba Raju KV

Abstract—The swift towards wireless sensor networks has motivated extensive research endeavours that target to reduce energy consumptions and end-to-end transmission delays. One such thread that aims to achieve is the packet scheduling algorithm. The multilevel priority packet scheduling schemes that target to reduce transmission delays, schedule data packets in a multilevel queue based on type of packet and in turn packets are scheduled within each level of queue based on shortest job first (SJF) and First Come First Serve (FCFS) to break the tie. The real difficulty with SJF algorithm lies in determining the processing time of next task. And FCFS increases transmission delays. To overcome the problems in the internal scheduling in multilevel queues in multilevel priority packet scheduling, we propose Deadline Perception with Enhanced Dynamic Multilevel Priority (DP-EDMP) packet scheduling. In the proposed scheme, data packets are first scheduled using type of packet among multiple levels of queue and then within each level of queue they are scheduled using Earliest Deadline First (EDF), thereby reducing average packet waiting time and end-to-end delay. Secondly, we remove the packets with expired deadlines from the medium which reduces data processing overhead and also saves energy consumptions of the sensor nodes. This facet is achieved by programming the sensor nodes to be intelligent enough to sense packets with expired deadlines.

3 To Study the Anticancer and Apoptotic Activity of Mentha arvensis. Linn in ROS Induced Buccal cells
Syama. M. Suresh, Dr. S. N. Suresh, Bindu Jacob, Sagadevan. P and Rathish Kumar. S

Abstract—The anticancer activity tested has shown notable activity against the cell lines. The present study confirms that the plant will be a potential source of medicine in future and extensive study is required for the discovery of new drugs on the active biological molecules. The methanolic leaf extract Mentha arvensis has shown significant cytoprotective activity too. The cell treated with H2O2 has a reduced viability than the methonolic leaf extract treated cells. In H2O2 treated cells the cytotoxicity was more than 70% i.e. only 34.76 % is viable and the cells treated with the methanolic leaf extract of M. arvensis has shown viability up to 54.23 %. It can be observed that addition of hydrogen peroxide produced approximately 79.3 % increase in DNA fragmentation which can be attributed to the DNA lesions formed by breaking phosphodiester bond in intact chromosomes by OH radicals. The plant extracts produced 63.7% decrease in DNA fragmentation indices suggesting potent cytoprotective effect against deleterious effects of hydrogen peroxide.

10 A New Approach Of Fault Current Mitigation By Using Dynamic Voltage Restorer
D.V.Srinivasarao, P.D.V.S.K Kishore

Abstract─This paper introduces and evaluates an auxiliary con-trol strategy for downstream fault current interruption in a radial distribution line by means of a dynamic voltage restorer (DVR). The proposed controller supplements the voltage-sag compensation control of the DVR. It does not require phase- locked loop and independently controls the magnitude and phase angle of the injected voltage for each phase. Fast least error squares digital filters are used to estimate the magnitude and phase of the measured voltages and effectively reduce the impacts of noise, harmonics, and disturbances on the estimated phasor parameters, and this enables effective fault current interrupting even under arcing fault conditions. The results of the simulation studies performed in the PSCAD/EMTDC software environment indicate that the proposed control scheme: 1) can limit the fault current to less than the nominal load current and restore the point of common coupling voltage within 10 ms; 2) can interrupt the fault current in less than two cycles; 3) limits the dc-link voltage rise and, thus, has no restrictions on the duration of fault current interruption; 4) performs satisfactorily even under arcing fault conditions; and 5) can interrupt the fault current under low dc-link voltage conditions.

A.R. Revathy Rajan, S. N. Suresh, P. Sagadevan.P. and S. Rathishkumar

Abstract - The phytochemical screening of methanolic leaf extract of Andrographis paniculata was tested for the presence of secondary metabolites such as Alkaloids, Terpenoids, Tannins, Saponins, Flavanoids and Steroids. The chemical constituents present in the methanolic leaf extract of A. paniculata was analyzed by GC-MS and the compounds were identified based on comparison of their retention indices (RI), retention time (RT) and mass spectra. Antifungal effect of the methanolic leaf extract of A. paniculata showed inhibitory effects against human pathogen, Candida albicans. This may be due to the presence of effective biochemical compound present in A. paniculata. The gene expression studies showed decreased level of Rfg1 gene expression in C. albicans upon treatment with methanolic leaf extracts of Andrographis paniculata. The Rfg1 gene was monitored after 48 hours treatment. The Rfg1 gene was re- expressed that shows the organism might have adapted to the environment and created the ability to defend the mode of action of the methanolic extract.

12 Transient Thermal Analysis Of A Diesel Engine Exhaust Valve
V Ramakrishna Reddy, R.Nava Sai Divya

Abstract-The valves used in the IC engines are of three types, Poppet or mushroom valve, Sleeve valve and Rotary valve. Of these three types, Poppet valve is most commonly used. Since both the inlet and exhaust valves are subjected to high temperatures of 1930°C to 2200°C during the power stroke, it is necessary that the materials of the valves should withstand these temperatures. The temperature at the inlet valve is less compared to exhaust valve. Thus the inlet valve is generally made of nickel chromium alloy steel and exhaust valve is made of silchrome steel. The aim of the project is to design an exhaust valve for a four wheeler diesel engine using theoretical calculations and 3D modelling is done in PRO-ENGINEER. Thermal analysis is to be done on the exhaust valve and analysis is done in ANSYS. Analysis will be conducted when the steady state condition is attained. Steady state condition is attained at 5000 cycles at the time of when valve is closed is 127.651 sec and valve is opened 127.659 sec. The material used for exhaust valve is EN52 steel. We are doing material optimization by doing analysis on material EN52. Static Modal analysis is also done on the exhaust valve to determine mode shapes of the valve for number of modes.

Abstract— This paper presents the design, analysis and implementation of a proposed combined three phase induction motor and its drive system to meet the demand of low-voltage electrical system for hybrid and electric cars, avoiding the high voltage human risks, expensive and complex requirements of the higher voltage insulation and power electronic devices. Development of Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs) will offer many new opportunities and challenges to the power electronics industry, especially in the development of the main traction motor drive.Cascade H-bridge (CHB) multilevel inverter with minimum output harmonics for electric/hybrid electric vehicle applications is proposed in this paper. Switching angles of switch devices are determined by selective harmonic elimination technique. So, the effect of low order harmonics are reduced, as a result the efficiency of system has improved. Moreover, the number of DC voltage sources that used in the proposed inverter is less than conventional multilevel inverters that leads to reduce the inverter costs A conventional 220V 3-ph induction motor has been rewound in order to get the required 48V 3-ph motor. The simulation results are obtained using MATLAB/SIMULINK software.

17 A Survey of Low Voltage in a Circuit Using LDO Regulator
R.Rajakumari

Abstract-A low-voltage low-dropout (LDO) regulator that converts an input of 1 V to an output of 0.85–0.5 V, with 90-nm CMOS technology is proposed. A simple symmetric operational transconductance amplifier is used as the error amplifier (EA), with a current splitting technique adopted to boost the gain. This also enhances the closed-loop bandwidth of the LDO regulator. In the rail-to-rail output stage of the EA, a power noise cancellation mechanism is formed, minimizing the size of the power MOS transistor. Furthermore, a fast responding transient accelerator is designed through the reuse of parts of the EA. These advantages allow the proposed LDO regulator to operate over a wide range of operating conditions while achieving 99.94% current efficiency, a 28-mV output variation for a 0–100 mA load transient, and a power supply rejection of roughly 50 dB over 0–100 kHz.

18 Analysis of Cyber-Physical System using FPGA-Based Plant-on-Chip Platform
T.Murugajothi

Abstract— Digital control systems are traditionally designed independent of their implementation platform, assuming constant sensor sampling rates and processor response times. Applica-tions are deployed to processors that are shared amongst control and noncontrol tasks, to maximize resource utilization. This potentially overlooks that computing mechanisms meant for improving average CPU usage, such as cache, interrupts, and task management through schedulers, contribute to nondeterministic interference between tasks. This response time jitter can result in reduced system stability, motivating further study by both the controls and computing communities to maximize CPU utilization, while maintaining physical system stability needs. In this letter, we describe an field-programmable gate array (FPGA)- based embedded software platform coupled with a hardware plant emulator (as opposed to purely software-based simulations or hardware-in-the-loop setups) that forms a basis for safe and accu-rate analysis of cyber- physical systems. We model and analyze an inverted pendulum to demonstrate that our setup can provide a significantly more accurate representation of a real system.

Abstract -In this paper the Finite Impulse Response (FIR) is designed using the montgomery multiplier. This multiplier is widely used in many cryptographic applications like RSA and elliptic curve cryptography. Here the multiplication is decomposed into number of independent units using an efficient algorithm to introduce the parallel processing. To reduce the latency a novel pre computed addition technique is followed. Since the Montgomery is a systolic multiplier it contains the features of regularity, modularity and unidirectional data flow and more suitable for VLSI design implementations. The important characteristic of this multiplier is it has an inbuilt truncation which compresses the LSB part and also consumes less area and power than existing designs.

32 A New PFC Rectifier for Air conditioner Applications
Tanneru Durga Prasad, N.Saida Rao

Abstract—With the widespread use of non-linear loads, such as variable speed drives (VSDs), power factor improvement has become more difficult. The presence of harmonic currents cause power capacitors to absorb them, as capacitor impedance is inversely proportional to frequency. The effects are overheating and increased dielectric stress of power capacitors, which result in their premature failure. These traditional approaches can also interact with harmonics, leading to harmonic amplifications at resonant frequency, which can damage the capacitors or components of the system. A new integrated three-level ac–dc converter is presented. The proposed converter integrates the operation of the boost power factor correction and the three-level dc–dc converter. The converter is made to operate with two independent controllers—an input controller that performs power factor correction and regulates the dc bus and an output controller that regulates the output voltage. The input controller prevents the dc-bus voltage from becoming excessive while still allowing a single-stage converter topology to be used. The paper explains the operation of the new converter in detail and discusses its features and a procedure for its proper design.

Abstract—MANET is the ad-hoc network that is a collection of mobile nodes in which it is needed that each node performs together. A node is called cooperative when it sends the data correctly to another node in a wireless network. In the mobille adhoc networks,the main role is played by the routting protocols in sequence to route the data from one mobile node to the other mobile node.But due to openness character of ad-hoc network, it is risk to face various kinds of attacks like black hole node attack etc .The ordinary used routing protocols in MANET are proactive, reactive and hybrid types but the reactive routing method is very trending method for the wireless network that supplies a scalable solution for network topologies used at a large scale.

35 A Survey on Low Complexity Active Learning for Semi-Supervised Clustering of Large Data Sets
P.Gandhini, S.Venkatesh Babu

Abstract—The main objective of Semi-supervised clustering is improving cluster performance by user’s guidance in the form of pairwise constraints named as must-link and cannot-link. The classifier uses users feedback during learning phase of classification is referred as Active learning. The active learning has the problem of satisfying the must required and not required constraints for semi supervised clustering. Active learning is achieved in an iterative manner. The concept of neighborhood of different clusters is formed according to the pair wise constraints. Under this, classic uncertainty-based principle is used and proposes a novel approach for estimating the uncertainty to each data point. This paper evaluates on eight bench mark data sets and its result achieves consistent and substantial improvements over its competitors. An active learning in iterative manner requires repeated reclustering of the data with an incrementally growing constraint set. This provides computational complexity for large data sets. To address this problem, we introduce an incremental semi-supervised clustering method that updates the existing clustering solution based on the neighborhood assignment for the new point. A naive batch active learning approach also proposed to select the top k points for active learning instead of selecting all data for training.

Abstract—Web database have become web-accessible through form-based search interfaces (i.e., search forms) that allow users to specify complex and precise queries to access the underlying database. Data are unstructured means which makes searching hard and traditional database querying impossible. Many Web pages (e.g. advertisements, weather reports, travel information and many others) contain an abundance of recognizable constants that together describe the essence of document content. In existing system document annotation is taken by CADS (Collaborative Adaptive Data Sharing platform) technique, that is client have annotated the document on creation time. In this paper, the problem of automatically extracting the keywords/metadata from web pages has been studied without any learning examples. An automatic annotation approach has been presented that extracts and aligns the data units on a result webpage. Then, for each webpage annotate from different aspects and summation the different annotations to predict a final annotation label for it. An annotation wrapper for the search site is without human intervention constructed and can be used to annotate new result pages from the same web database.

K. Seetharamanjaneyulu, G.Nagaraju

Abstract— This paper presents a control algorithm based on enhanced phase-locked loop (EPLL) for distribution static compensator (DSTATCOM) to compensate reactive power, to provide load balancing, to eliminate harmonics, to correct power factor, and to regulate point of common coupling (PCC) voltages under linear and nonlinear loads. In this approach, an extraction of fundamental active and reactive power components of load current for the estimation of source currents includes a signal-processing algorithm based on the EPLL scheme. The proposed control algorithm is implemented using a digital signal processor. Test results on a developed DSTATCOM are presented to validate the proposed control algorithm for compensation of reactive power, load balancing, harmonics elimination, power factor correction, and zero voltage regulation at PCC. A DSTATCOM injects a current into the system to provide for the reactive component of the load current. The validity of proposed method and achievement of desired compensation are confirmed by the results of the simulation in MATLAB/ Simulink.

42 Adaptive Voltage Control Using Multiple Distributed Energy Resources with Fuzzy Controller
P.Nagarjuna, P.Ravi Kumar

Abstract-Distributed energy resources (DE) with power electronics interfaces and logic control using local measurements are capable of providing reactive power related to ancillary system services. In particular, local voltage regulation has drawn much attention in regards to power system reliability and voltage stability, especially from past major cascading outages. This dissertation addresses the challenges of controlling the DEs to regulate the local voltage in distribution systems. First, an adaptive voltage control method has been proposed to dynamically modify the control parameters of a single DE to respond to system changes such that the ideal response can be achieved. Then, control methods have been discussed in the case of multiple DEs regulating voltages considering the availability of communications among all the DEs. When communications are readily available, a method is proposed to directly calculate the needed adaptive change of the DE control parameters in order to achieve the ideal response. When there is no communication available, an approach to adaptively and incrementally adjust the control parameters based on the local voltage changes is proposed. Since the proposed adaptive voltage regulation method in the case of multiple Des without communication, has a high tolerance to real-time data shortage and can still provide good enough performance, it is more suitable for broad utility applications. The approach of multiple DEs with communication can be considered as a high-end solution, which gives faster and more precise results at a higher cost.

43 A New Method For Image Steganography Using Rsa Algorithm
Rajkumar Yadav

Abstract-The aim of proposed scheme is to make a more secure and robust method of information exchange so that confidential and private data must be protected against attacks and illegal access. To order to achieve the required robustness and security cryptography and steganography is combined. Image is taken as a cover medium for steganography and RSA algorithm is used for encryption. In this proposed method advanced LSB bit manipulation method is used for embedding the message in the image file and the message is itself encrypted using the RSA encryption method. For embedding the text in image file firstly both the text and image file are converted into binary equivalent and then text is encrypted using RSA. The encrypted text is then embedded into the image file using the advanced LSB algorithm. At the receiver side, embedded image file must be selected to extract the message .After selecting the file and advanced LSB method is applied to extract the encrypted message and this message is decrypted using the RSA algorithm. A comparison is made between the original image file and the embedded one to indicate that less distortion even after changing the LSB bit of original file and for this PSNR, RMSE is calculated. PSNR and RMSE value indicates imperceptibility and transparency is evaluated by comparing the graph of image file before and after steganography.

44 A Novel Hierarchical Algorithm for Document Clustering
Nanimela Kamakshi, A Srinivasan, Dr.M.Giri

Abstract-All clustering methods have to assume some cluster relationship among the data objects that they are applied on. Similarity between a pair of objects can be defined either explicitly or implicitly. In this paper, we introduce a novel multi-viewpoint based similarity measure and two related clustering methods. The major difference between a traditional dissimilarity/similarity measure and ours is that the former uses only a single viewpoint, which is the origin, while the latter utilizes many different viewpoints, which are objects assumed to not be in the same cluster with the two objects being measured. Using multiple viewpoints, more informative assessment of similarity could be achieved. Theoretical analysis and empirical study are conducted to support this claim. Two criterion functions for document clustering are proposed based on this new measure. We compare them with several well -known clustering algorithms that use other popular similarity measures on various document collections to verify the advantages of our proposal.

45 Speed Optimized 2D DCT Implementation for High Compression Rate Applications
K.Santhosh Kumar, B.N. Srinivasa Rao

Abstract-Multimedia applications, and in particular the encoding and decoding of standard image and video formats, are usually a typical target for Systems on Chip (SoC). The bi-dimensional Discrete Cosine Transformation (2D-DCT) is a commonly used frequency transformation in graphic compression algorithms. Many hardware implementations, adopting disparate algorithms, have been proposed for Field Programmable Gate Arrays (FPGA). These designs focus either on performance or area, and often do not succeed in balancing the two aspects. This paper presents two high performance FPGA architectures for the 2D DCT computation for Ultra High Definition video coding systems. Both architectures use Distributed Arithmetic to perform the necessary multiplications instead of traditional multipliers. The first architecture uses 105 clock cycles to transform an 8x8 block and reaches a rate of up to 206 samples per second at a 338.5 MHz frequency, while the second one requires 65 cycles for each 8x8 block and achieves a rate equal to 252 samples per second at 256 MHz’s Both architectures have been implemented using VHDL. Virtex7 FPGA of Xilinx has been used for the realization of both implementations.

Ch.Vasantha Lakshmi, A.V.Ramana Rao, G.Satish, M.Suryanarayana

Abstract-It is to conduct stress analysis of a pressure vessel shell at the radial openings on the surface. The radial openings are not avoided from the surface of shell due to various piping attachments. Hence the stress analysis of shell and its ultimate failure under internal pressure beyond elastic limit is an appropriate scenario. The plastic zone appearing in vicinity of internal surface of cylinder propagates more fastly along radial openings side. When cylinder is unloaded it will cause reverse plasticity. Therefore it is proposed to obtain numerical solution using Finite Element analysis of cylindrical shell to obtain the displacement & radial stress distribution. In the work the stress analysis of pressure vessel shells with different pressure conditions is conducted Elastic analysis of uniform cylindrical shell with radial openings is found by Finite element method. It is observed that there are several factors which influence stress intensity factors. The Finite element analysis is conducted using Solid Edge. The results are presented in form of graphs and tables.

54 A New Converter for Dc Motor Applications with Power Factor Correction
R.Ramanjan Prasad, N.Srikanth

Abstract-Generally non-linear loads are the main source of harmonics. This paper presents one new control scheme to compensate the harmonic current generated by the diode rectifier so as to achieve a power factor nearer to unity and regulate the DC-bus voltage. This scheme uses one PFC Boost Converter which is connected in shunt with the diode rectifier to compensate the harmonic current drawn by the single phase diode rectifier. The line current command is derived from a dc link voltage regulator and an output power estimator. The hysteresis current controller is used to track the line current command. In absence of diode rectifier (Non-linear Load), the PFC boost converter draws purely sinusoidal current from source. In presence of diode rectifier the PFC boost converter draws current in such a way that the total current drawn from source becomes purely sinusoidal. Merits of the proposed converters include higher power density, simpler control strategy, less harmonic control contents, nearly unity power factor and unidirectional power flow. Optional principle, design analysis and conditions achieving for the proposed converters are described.

55 Analysis of Multilevel Inverter topology with a reversing-voltage Concept
N. Devipriya, G Madhusagarbabu

Abstract-Multi level inverter is used in applications that need high voltage and high current. The topologies of multilevel inverter have several advantages such as lower THD, lower EMI generation, better output waveform and higher efficiency for a given quality of output waveform. The main feature of multilevel inverter is the ability to reduce the voltage stress on each power device due to the utilization of multilevel on the DC bus. However, it has some disadvantages such as increased number of components, complex pulse width modulation control method, and voltage-balancing problem. In this paper, a topology with a reversing-voltage component is proposed to improve the multilevel performance by compensating the disadvantages mentioned. This topology compared to existing inverters requires fewer components (particularly in higher levels) and requires fewer carrier signals and gate drives. Therefore, the overall cost and complexity are greatly reduced particularly for higher output voltage levels. Finally, the paper includes simulation results of RVMLI fed Single phase Induction Motor using In-phase Disposition (IPD) PWM technique.

B Venkata Sai Ravi Teja Yadav

Abstract-We present a high-speed, clockless, serial link transceiver for inter-chip communication in asynchronous VLSI systems. Serial link transceivers achieve high off-chip data rates by using multiplexing transmitters and de-multiplexing receivers that interface parallel on-chip data paths with high-speed, serial off-chip buses. While syn-chronous transceivers commonly use multi-phase clocks to control the data multiplexing and demultiplexing, our clock-less transceiver uses a token-ring architecture that elim-inates complex clock generation and synchronization cir-cuitry. Furthermore, our clockless receiver dynamically self-adjusts its sampling rate to match the bit rate of the transmitter. Our SPICE simulations report that in a 0.18-m CMOS technology this transceiver design operates at up to 3-Gb/s and dissipates 77 mW of power with a 1.8-V supply voltage.

Abstract-New age gas turbine engines are targeted to operate at increased turbine inlet temperatures to attain higher thrusts and this is making the combustor liners to operate at temperatures beyond the permissible metal temperatures from metallurgical point of view. This is necessitating the combustor designers to develop several advanced cooling techniques. Film cooling has been the traditional and most widely used cooling technique for gas turbine combustor liners. Most of the research on film cooling of combustor liners is experimental in nature and several correlations were developed towards understanding this. Of late, Computational Fluid Dynamic (CFD) studies of film cooling have met with varying degrees of success. In this present work, CFD analysis of film cooling process has been studied using Fluent. Initially, code validation studies have been conducted by analyzing the flow on a flat plate and in a film cooling setup using the data published in literature. Subsequently, CFD analysis of a cooling ring test setup designed and developed by GTRE has been carried out. Several parametric CFD studies were also carried out to study the effect of hole diameter, hot gas temperature and coolant flow rate on the film cooling performance.

61 Design of ZVS Half-Bridge Series Resonant Inverter with Improved Efficiency for Induction Heating Applications
P. Saikrishna , T. Kavitha

Abstract-Nowadays, the induction heating market is continuously growing due to its benefits including precise output power control, high efficiency, reduced heating times, and cleanness. The maximum output power and efficiency are achieved at the resonant frequency, and if the switching frequency is increased the output power will get reduced. As a consequence, in these converters, the efficiency is also reduced in the low-medium output power range appliances. Most of the circuit structures in large capacity devices were adapted with Full-bridge structures in Inverter. Because of the high power density and the reduced cooling capabilities, efficiency becomes critical in this application. In this study, a half-bridge series resonant inverter driven by a variable -frequency was implemented in an inductive heating-facility in which the circuit was adapted Resonant- Transition in Zero-Voltage-Switching (ZVS). The proposed variable frequency duty cycle (VFDC) control is intended to improve the efficiency in the medium and low output power levels because of the decreased switching frequencies. This paper presents a new Design circuit topology and its digital control scheme for a ZVS Half-Bridge Series Resonant Inverter circuit with improved efficiency for Domestic induction heating appliances. The proposed circuit is implemented and simulated by using MATLAB software.

Abstract-Even many techniques proposed the Modeling and designing of the PV Cell and its interface to the grid, it suffers from many controlling problems due the nonlinear characteristics of the Load. This paper presents a fuzzy logic control for controlling the dc voltage in predictive control scheme. The Four-Leg voltage source inverter is used to inject power. The inverter can thus be utilized as: 1) power converter to inject power generated from RES to the grid, and 2) shunt APF to compensate current unbalance, load current harmonics, load reactive power demand and load neutral current. All of these functions may be accomplished either individually or simultaneously. With such a control, the combination of grid-interfacing inverter and the 3-phase 4-wire linear/non-linear unbalanced load at point of common coupling appears as balanced linear load to the grid.

Abstract-In recent years, renewable energy sources such as photovoltaic (PV), wind, fuel cell, etc gain importance due to the limitations of conventional energy sources. Renewable energy sources play an important role in rural areas where the power transmission from conventional energy sources is difficult. Other advantages of renewable energy sources are clean, light and does not pollute atmosphere. Hybrid electric vehicles (HEVs) powered by electric machines and an internal combustion engine (ICE) are a promising mean of reducing emissions and fuel consumption without compromising vehicle functionality and driving performances. The proposed integrated circuit allows the permanent magnet synchronous motor to operate in motor mode or acts as boost inductors of the boost converter, and thereby boosting the output torque coupled to the same transmission system or dc-link voltage of the inverter connected to the output of the integrated circuit. Electric Motors, those are used for EV propulsion must have high efficiency for maximum utilization of the energy from batteries and/or fuel cells. A new control technique for the proposed integrated circuit under boost converter mode is proposed to increase the efficiency. Since the light load performance is in recent focus of interest, appropriate algorithms to improve light load efficiency were implemented. The proposed control technique is to use interleaved control to significantly reduce the current ripple and thereby reducing the losses and thermal stress under heavy-load condition. When pv fed inverter/converter circuit is operated for single input under closed loop, multiple outputs are obtained.
