Abstract

A zero-voltage-transition(ZVT) full bridge (FB) boost converter for single stage power factor correction (PFC) in distributed power system is proposed. A simple auxiliary circuit provides zero-voltage-switching(ZVS) condition to all semiconductor devices without imposing additional voltage and current stresses and loss of PWM capability. The proposed boost converter provides both input power factor correction and direct conversion from $110{\sim}220VAC$ line to 300VDC bus with single power stage. Operational principle, analysis of the proposed converter are described and verified by computer simulation and experimental results from a 1.5 kW, 80 kHz laboratory prototype.
