Title

A Bi-Flyback Pfc Converter With Low Intermediate Bus Voltage And Tight Output Voltage Regulation For Universal Input Applications

Abstract

A single-stage Bi-flyback power factor correction topology is proposed in this paper. By adding a secondary winding to BIFRED choke inductor, there are two discharging paths for choke inductor: to load or to intermediate capacitor. In this topology, the intermediate bus voltage will be limited to below 400 VDC for universal voltage applications, and DC/DC conversion cell can operate in CCM. A 150 W prototype unit based on this topology has been built and tested in the lab with experimental results that show good performance.
