Abstract: A dual-mode active clamp flyback converter includes a transformer circuit, a clamping energy storage circuit, and a main switch circuit. The transformer circuit is coupled to a load, and the transformer circuit includes an auxiliary winding. The clamping energy storage circuit is coupled to the transformer circuit. If the load as a heavy loading, the clamping energy storage circuit is turned on. If the load as a light loading, the clamping energy storage circuit is turned off. The main switch circuit is coupled to the transformer circuit. When the main switch circuit is turned on, the auxiliary winding releases energy to a primary-side winding of the transformer circuit.
