Abstract
The invention concerns a direct energy-transfer converter of the AC/AC or DC/DC type, including a self-regulated synchronous rectifier, in which the rectifier switches are controlled through one or more transformer windings. The converter includes a primary stage with at least one primary winding of a transformer and at least one controlled switch, with a secondary stage having at least one secondary winding () of the transformer, and a synchronous rectifier () with at least a first switch () which is self-regulated and conducting during the conducting phase of the controlled switch of the primary stage, known as the direct energy-transfer stage, and at least one secondary switch () which is self-regulated and conducting during the non-conducting phase of the controlled switch of the primary stage, known as the freewheel phase, and an output filter (). Said converter also includes the means (CTC) to render conducting said second switch () independently of the voltage at the terminals of the secondary winding () during said freewheel phase.
