Abstract :
A novel zero-voltage-transition (ZVT) isolated PWM boost power converter for single stage power factor correction (PFC) is presented to improve the performance of the previously presented ZVT power converter. A simple auxiliary circuit which includes only one active switch provides zero-voltage-switching (ZVS) condition to all semiconductor devices (two active switches are required for the previous ZVT converter). This leads to reduced cost and simplified control circuit comparing to the previous ZVT converter. The ZVS is achieved for wide line and load ranges with minimum device voltage and current stresses. Operation principle, control strategy and features of the proposed converter are presented and verified by the experimental results from a 1.5 kW, 100 kHz laboratory prototype
