High-power-factor soft-switched boost converter

A novel implementation of the high-power-factor (HPF) boost converter with active snubber is described. The snubber circuit reduces the reverse-recovery-related losses of the rectifier and also provides zero-voltage switching for the boost switch and zero-current switching for the auxiliary switch. The performance of the proposed approach was evaluated on an 80-kHz, 1.5-kW, universal-line range, HPF boost converter. The proposed technique improves the efficiency by approximately 2% at full load and low line.
