Analysis of PFC Boost Converter with Soft-switching Configuration

Abstract

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 of proposed converter seems to eliminate 3rd harmonic component. we have performed the analysis of 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.
