摘要：

A hybrid resonant pulse-width modulation (PWM) bridgeless ac-dc power factor correction (PFC) boost converter is proposed for application in power supplies and battery chargers. The bridgeless operation of the proposed converter eliminates the need for the front-end diode bridge rectifier. The PWM switches share the same gating signal, so the converter does not need extra circuitry to sense the positive or negative ac input line-cycle operation. The resonant tank components are relatively small in size and, unlike a totem-pole PFC converter, the hybrid-resonant mode of operation alleviates the reverse-recovery losses for the body diodes of the PWM switches. The inherent inrush current-limiting capabilities improve the system reliability. Moreover, the converter architecture enables simple implementation of lightning and surge protection systems. To verify the proof of concept, experimental results are presented for a 650-W prototype at 70-kHz switching frequency, universal ac input, and 400-V dc output.
