7. Doo-Yong Jung, Young-Hyok Ji, Sang-Hoon Park, Yong-Chae Jung, and Chung-Yuen Won ‘Interleaved Soft-Switching Boost Converter for Photovoltaic Power-Generation System’
Senior Member, IEEE April 2011.This paper represent Interleaved Soft-Switching Boost Converter for Photovoltaic Power-Generation System a interleaved soft switching boost converter (ISSBC) for a photovoltaic (PV) power-generation system is proposed. The topology used raises the efficiency for the dc/dc converter of the PV power conditioning system (PVPCS), and it minimizes switching losses by adopting a resonant soft-switching method and mode analysis of the proposed topology is presented. The feasibility of the proposed topology is
experimentally verified for a 1.2-kW prototype. The experimental results imply that 97.28% efficiency is achieved under the full-load condition. Consequently, it is confirmed that the overall efficiency is increased by about 1.5% compared with the conventional hard switching interleaved boost converter.

8. Ilan Aharon, Student Member, IEEE, Alon Kuperman, Member, IEEE, and Doron Shmilovitz, Senior Member February 2015.’ Analysis of Dual-Carrier Modulator for Bidirectional Non inverting Buck’Boost Converter’.This paper represents A pulse-width modulation modulator for a non inverting bidirectional buck’boost converter is analyzasion and a corresponding average-mode current controller design is revealed. The main feature of the modulator is the ability to create switching sequences for both converter legs without requiring any information regarding either operation mode or the direction of power flow. The modulator receives a control signal generated by the current controller, and a triangular carrier and generates driving signals with two different duty cycles, allowing tight control of the inductor current throughout the entire operating range. The underlying circuitry is thus relatively simple; moreover, the proposed method greatly simplifies the outer loop controller design. The revealed findings are supported by simulations and experiments.

Dr.R.Seyezhai, R.Anitha , S.Mahalakshmi, M..Bhavani ‘ Simulation and Implementation of High Gain Interleaved Boost Converter for Fuel cell Applications’IJIRCCE July 2013.This paper represent objective of design and implement a high gain interleaved converter using switched capacitors for fuel cell systems. Fuel cell is one of the promising technologies for distributed generation. For designing high efficiency fuel cell power systems, a suitable DC- DC converter is required. Among the various topologies, interleaved converters using switched capacitor are considered as a better solution for fuel cell systems due to high conversion efficiency. In the proposed interleaved converter, the front end inductors are magnetically cross- coupled to improve the electrical performance and reduce the weight and size. Also, switched capacitors are used to improve the voltage gain of the converter. The proposed converter has been performed. Simulation study of interleaved converter using switched capacitors interfaced with fuel cells has been studied using MATLAB/SIMULINK.A prototype has been developed to verify the simulation results.

10. Farag. S. Alargt , Ahmed. S. Ashur ‘ Analysis and Simulation of Interleaved Boost Converter for Automotive Applications’IJEIT May 2013.This paper represent design and simulation of multi-phase interleaved boost DC-DC converter. The control strategy of the converter is based on a voltage mode-controlled Pulse Width Modulation (PWM) with a Proportional-Integral-Derivative (PID) controller. The proposed converter used 1KW power and 42V output voltage to satisfy the requirements of usage in 14/42 power system used in automotive applications. The conception, analysis and simulation of a multi-phase interleaved DC-DC boost converter for 42V power systems are presented. One kilowatt interleaved three-phase boost converter designed to operate in a Discontinuous Conduction Mode (DCM).. The results show that the system is stable and well behaved under input voltage variations and the output voltage remains within the desired specified limits presented in automotive standards.

AHMED MAJEED GHADHBAN, Diyala University, Electrical Power and Machines Engineering Department,Collage of Engineering ‘Design of a closed loop control of the boost convert’,IJERGS Nov 2014.This paper represent design of closed loop control of the boost converter based on specific criteria given. The closed loop boost converter is used to convert a low level DC input voltage from a DC power supply and use to control the average model. The simulation carried out in Pspice software. The Performance analysis, which covers the closed loop control of the average model on related waveforms of output voltage, current and power are discussed and achieved.

12. Athimulam Kalirasu, Subharensu Sekar Dash,Serbian ‘Simulation of Closed Loop Controlled Boost Converter for Solar Installation’journal of Electrical Engineering May 2010 .This paper represent With the shortage of the energy and ever increasing of the oil price, research on the renewable and green energy sources, especially the solar array sand the fuel cells, becomes more and more important. How to achieve high stepup and high efficiency DC/DC converters is the major consideration in the renewable power applications due to the low voltage of PV arrays and fuel cells. In this paper digital simulation of closed loop controlled boost converter for solar installation is presented. Circuit models for open loop and closed loop controlled systems are developed using the blocks of simulink. The simulation results are compared with the theoretical results. This converter has advantages like improved power factor, fast response and reduced hardware.
