Zero-voltage-switching totem-pole bridgeless boost rectifier with reduced reverse-recovery problem for power factor correction

Abstract

A novel totem-pole bridgeless boost rectifier with ZVS operation is proposed for power factor correction. In the proposed rectifier, conduction losses are lowered by eliminating full-bridge diode rectifier. Moreover, the proposed rectifier can achieve zero-current-switching (ZCS) turn-off of diodes, which eliminates the reverse-recovery problems of the body… (More)
