A Design of AC-DC Converter using Bi-directional Partial Resonant Soft-Switching

양방향 부분공진 소프트 스위칭을 적용한 AC-DC컨버터의 설계

This paper proposes a bi-directional current switch with snubber regeneration using Power MOSFETs and this paper proposes to use a loss-less snubber with switching device to perform soft-switching. It results in not only decreasing switching loss in the device drastically, but also improving input ac current waveform distortion. The computer simulation results show that the input current waveform and show the requirements necessary for the elimination of the 3rd harmonic component. We also show the procedure to design the parameters of the converter.
