In this paper, a power factor correction (PFC) based on active-clamped full-wave quasi-resonant (ZCS-QR) boost converter is presented. This circuit is characterized by zero-voltage-switched (ZVS) and zero-current-switched (ZCS) that results in higher efficiency, opens possibility to incorporate higher switching frequency, and has some potency to reduce converter's conducted EMI. The working principle and steady state performance of the proposed converter are presented. A 100 V dc input, 180 W maximum output, and 440 kHz resonant frequency experimental circuit has been built. Maximum efficiency of 93% and the proof of compliance to the IEC61000-3-2 class D have been confirmed by experiment.
