Abstract

This paper presents a Single-phase Semi-Bridge PWM Converter, which features Continuos Conduction Mode and Phase-adjusted Unipolar PWM Method. 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 principle of operation, a design example and Simulation results of a 3kW Semi-Bridge PWM converter with 220 Vrms input voltage and 400 Vdc output voltage are presented.
