Design and Analysis of Fast and Zero Voltage Switching Of Interleaved Flyback Converter with H6 Type Inverter for Photovoltaic Applications

Abstract

A design and load analysis of interleaved flyback converter with H6 inverter topology is proposed. Flyback converter is one among the DC-DC converter with high frequency which is used or low power applications. Because of high frequency operation switching losses and stresses are more. To reduce stresses and losses across the switch of interleaved flyback converter is proposed. In the grid tied inverter system leakage current is one of the disadvantages and to avoid this H6 type inverter is used. With this advantage of H6 inverter and flyback converter this paper is mainly focused on stresses across switches and eliminating leakage current, harmonic reduction. Further the fast switching is proposed within converter in order to deliver maximum power transfer delivered to load through grid. To validate the overall perfortmance the proposed converter modeled in MATLAN-SIMULINK and prototype developed using DSP DSP TMS320F28377S and connected to grid connected load.
