ABSTRACT:
A transition mode power converter having an active snubber the operation of which is controlled using an auxiliary winding on the transformer of the power converter. In one embodiment, the power converter includes a transformer having a primary winding connected to a voltage source, a primary switch, an auxiliary switch, a capacitor, and an auxiliary winding on the transformer. The primary switch includes a first terminal connected to the primary winding of the transformer and a second terminal connected to a common node. The auxiliary switch includes a first terminal connected to the voltage source and to the primary winding. The capacitor is connected between a second terminal of the auxiliary switch and the first terminal of the primary switch. The auxiliary winding of the transformer is connected to a third terminal of the auxiliary switch and controls operation of the auxiliary switch via the third terminal.
