Abstract: An Active Clamp Flyback (ACF) converter includes a transformer module, a clamping module, and a controller. The controller is configured to: after the transformer module starts secondary side discharging, control the clamping module to start receiving leakage inductance power from the transformer module; and after controlling the clamping module to stop receiving the leakage inductance power from the transformer module, control the clamping module to release the leakage inductance power to the transformer module. The leakage inductance power released by the clamping module to the transformer module is used by the transformer module to restore a soft switching state based on the leakage inductance power. In a process of transferring the leakage inductance power to a clamping capacitor, the clamping module is in an enabled state. This reduces a loss caused by the clamping module to the leakage inductance power, and helps reduce overall loss caused by the ACF converter.
