Abstract

A novel zero-voltage-transition (ZVT) isolated PWM boost converter for single stage power factor correction (PFC) is presented. A simple auxiliary circuit added in the secondary rectifier side provides zero-voltage-switching (ZVS) condition to all semiconductor devices without increasing additional device voltage and current stresses. The proposed converter gives both input power factor correction and direct conversion from AC line to DC output, which leads to high efficiency and high power density conversion. Operation principle, analysis, and features of the proposed converter are presented and verified by the computer simulation and experimental results from a 1.5 kW, 80 kHz laboratory prototype
