A control method for a four-switch buck-boost converter is provided. The control method adopts four-stage control, and divides the load range into two sections and adopts different control strategies according to a critical load value corresponding to optimal control. In Boost mode, before the critical load, Tand Tare kept constant, Tis a minimum value for realizing soft-switching, and Tdecreases with the increase of the load; when the critical load is reached, Tdrops to 0; and after the critical load, T, T, Tand T increase with the load. In Buck mode, before the critical load, Tand Tare kept constant, Tis a minimum value for realizing soft-switching, and Tdecreases with the increase of the load; when the critical load is reached, Tdrops to 0; and after the critical load, T, T, Tand T increase with the load.

The invention discloses a self-adaptive synchronous rectification control system and a self-adaptive synchronous rectification control method of an active clamp flyback converter. The control system comprises a sampling and signal processing circuit, a control circuit with a microcontroller as a core and a gate driver. According to the control method, a switching-on state, an early switching-off state, a late switching-off state and an exact switching-off state of a secondary synchronous rectifier of the active clamp flyback converter can be directly detected, and the synchronous rectifier and a switching-on time of the synchronous rectifier in next cycle can be controlled according to a detection result. After several cycles of self-adaptive control, the synchronous rectifier enters the exact switching-on state, thus avoiding oscillation of an output waveform of the active clamp flyback converter.
