Abstract
In this paper, we proposed the alternated forward multi-resonant converter. It can reduce the voltage stress due to the operation of two multi resonant switches and also provides a high frequency applications. The proposed circuit is verified through the PSpice simulation and the 50W experimental set with 2MHz maximum frequency. The measured voltage stress is up to 170V of 2.9 times the input voltage and the efficiency is about 81.66% at low line.
