For use with an asymmetrical half-bridge power converter having a primary switching circuit coupled to a primary winding of a transformer and a rectifier coupled to a secondary winding of the transformer, a reverse recovery circuit a method of operation thereof. In one embodiment, the reverse recovery circuit includes an inductor that reduces current spikes in the primary switching circuit caused by a reverse recovery phenomenon associated with the rectifier. The reverse recovery circuit also includes a diode, coupled to the inductor, that clamps a voltage across the rectifier.
