The power factor correction circuit includes a first bridge arm, a second bridge arm, an output capacitor and an active clamp unit. The control method includes steps of providing a first driving waveform to control a main switch, providing a second driving waveform to control an auxiliary switch, and providing a third driving signal to control a fifth switch. A first delay time is between the turning-off time point of the third driving signal and the turning-on time point of the first driving waveform, a second delay time is between the turning-on time point of the first driving waveform and the turning-off time point of the second driving waveform, and a third delay time is between the turning-off time point of the second driving waveform and the turning-on time point of the third driving signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control method for power factor correction circuit","description":"A control method for a power factor correction circuit is disclosed.
