Abstract
A synchronous rectifier having two MOSFETs and a transformer with a primary winding and a first and second secondary winding in the transformer and a control device in the rectifier circuitry. The second secondary winding (tertiary winding) and the control device are connected within the synchronous rectifier to provide protection for the two MOSFETs from destruction caused by reverse feed.
