The control method comprises: generating a first switch signal according to an output voltage and a current sensing signal, and selectively generating a second switch signal in a complementary or non-complementary control mode according to the current sensing signal and the first switch signal. The first switch signal is coupled to drive a low-side power switch for switching a transformer and the output voltage regulation of the active-clamp flyback power converter. The second switch signal is coupled to drive a high-side power switch for recycling leakage energy of the transformer and achieving a soft-switching of the low-side power switch. With the control method, the high-side power switch can adaptively switch in a complementary or non-complementary control mode depending on the output load and input voltage conditions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control circuits and methods for active-clamp flyback power converters","description":"A method for controlling an active-clamp flyback power converter is provided.
