Abstract
This paper presents a novel single-phase unity power factor rectifier, whic h features critical conduction mode and zero-voltage switching. The reduced conduction losses are achieved by the employment of a single converter, in stead of the typical configuration composed of a front-end rectifier follow ed by a boost converter. Theoretical analysis, a design example, and experi mental results of a 300-W converter with 127-V-rms input voltage and 400-V- DC output voltage are presented.
