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. The disclosure adopts the trailing edge non-complementary mode to reduce a circulating current of the converter, uses the leading edge non-complementary mode to replace the ordinary flyback mode to improve light load efficiency, and uses the leading-edge non-complementary Burst mode at no-load to limit a peak current of a primary side in leading-edge non-complementary Burst mode to avoid generation of audio noise, and allowing a low no-load power consumption.
