Abstract

This paper presentes a novel single-phase unity power factor rectifer, which features Critical Conduction Mode and ZVS. The reduced conduction losses are achieved by the employment of a single converter instead of the typical configuration composed of a front end rectifier followed by a boost converter. Theoretical analysis, a design example and experimental results of a 300 converter with $127V_{rms}$ input voltage and 400 VDC output voltage are presented.
