A New Boost-Flyback Converter without Any Auxiliary Switch forPhotovoltaic System

In this paper, a novel lossless snubber for a high-stepupconverter is presented, so to reduce voltage stress on theconverter switch and to provide the zero current switchingconditions for the switch and converter diodes. The proposedconverter is fully analyzed and compared with previous similarconverters. The proposed converter is simulated in PSPICEsoftware and its results confirm the theoretical analysis of theconverter.
