Abstract: This disclosure provides a multi-mode control method for an active clamp flyback converter. In the flyback converter, the controller realizes mode switching between a trailing edge non-complementary mode, a leading edge non-complementary mode, and a leading edge non-complementary Burst mode of two driving signals after comparing a detection feedback voltage with the set mode switching threshold voltages.
