The first bridge arm includes a first switch and a second switch in series. The second bridge arm includes a third switch and a fourth switch in series. The active clamp unit includes a second inductor, a clamp capacitor and a fifth switch. The power factor correction circuit may realize the ZVS function of the first switch and the second switch by the collaboration of the active clamp unit and the conduction/non-conducting state of the first switch, the second switch, the third switch and the fourth switch."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power factor correction circuit","description":"A power factor correction circuit includes an input power source, a first bridge arm, a second bridge arm, an output capacitor and an active clamp unit.
