Abstract

In this paper, we deal with the operational processing principle of the AT forward MRC (multi-resonant converter), which can reduce the resonant voltage stress up to 2~3 times the input voltage using two input capacitors and two multi-resonant switches in series. The eight equivalent circuits are obtained in this converter during a switching period. The operational principle of the resonant converter is verified through the characteristics of the experimental converter with 48 V input voltage, 5 V/50 W output voltage/power and PSpice simulation. The measured maximum voltage stress is 170 V of 2.9 times the input voltage and the maximum efficiency is measured up to 81.66%
