교번으로 영전압 스위칭되는 다중공진형 컨버터 토폴로지

Abstract

In the resonant converters which can provide high efficiency and high power density, the resonant voltage stress is about 4—5 times the input voltage. It needs the power switch with high ratings This is a reason why the conduction loss is increased In this paper, it proposes the alternately zero voltage switched forward, flyback multi resonant converter topology for reducing the voltage stress using alternately zero voltage switching technique And the proposed AT forward MRC is experimentally considered about the loop gain with HP4194A network analyzer.
