A Novel Flyback Converter with High Efficiency

Abstract

This study proposes a flyback converter with high efficiency compared to the conventional flyback converter. The primary stage is similar to that of an asymmetric hybrid converter. Secondary side consists of an active clamp circuit. The LC components in primary and secondary side resonate, aiding in Zero Voltage Switching (ZVS) and Zero Current Switching (ZCS) of switches and diodes. Simulation works are done in MATLAB/SIMULINK.

Keywords: Dc-Dc power converters, resonance, ZVS, ZCS
