JEE_V7_N4_RP1 Sinu K.J. Sathishkumar Rajangam Muthukumarasamy Journal on Electrical Engineering 2230 – 7176 7 4 1 8 Boost Converter, Coupled Inductor, High Voltage Gain, Reverse Recovery, Zero-Voltage Switching (ZVS) In this paper a soft switching dc–dc converter with high voltage gain and low over voltage stress and harmonics is proposed. It consists of a ZVS boost converter stage and a ZVS half-bridge converter stage and the two stages are merged into a single stage. The ZVS boost converter stage pro- vides a continuous input current and ZVS operation of the power switches. The ZVS half-bridge converter stage provides a high voltage gain. The principle of operation and the system analysis are presented in this paper. Theoretical analysis and performance of the proposed converter were verified on a 100W experimental prototype operating at 108 kHz switching frequency. Here both the ZVS and ZCS is done. It reduces the overvoltage stress and harmonics. April - June 2014 Copyright © 2014 i-manager publications.
