A Snubber Cell For Single-Stage Pfc With A Boost Type Input Current Shaper And Isolated Dc/Dc Converter

Abstract

This paper proposes a lossless snubber cell for all single-stage PFC with a boost type input current shaper and an isolated dc/dc converter. The single auxiliary switch of the snubber cell shares the same switching signal as the PFC main switch; both switches operate under soft switching way. Various stages of the switching cycle have been comprehensively analyzed to explain the operation principle of the soft switching transition. This soft switching technique reduces switching power loss and improves efficiency. The simulation results verify the practicable of the new snubber cell. 100W prototypes are built on the bi-flyback PFC converter and the BIFRED PFC converter; experimental waveforms match with simulation results. © 2011 IEEE.
