摘要：A DC converter has a transformer with loosely coupled primary and secondarywindings, a main switch connected in series with the primary winding of the transformer,and a series circuit connected to ends of one of the primary winding and main switch. Theseries circuit includes a clamp capacitor and an auxiliary switch. The main and auxiliary
switches are alternately turned on/off so that a voltage of the secondary winding of thetransformer is synchronously rectified with synchronous rectifiers and is smoothed withsmoothing elements, to provide a DC output. The DC converter also includes a tertiarywinding tightly coupled with the primary winding of the transformer, a voltage source tosupply a voltage lower than a voltage generated by the tertiary winding of thetransformer, and clamp diodes to clamp the voltage generated by the tertiary windingwith the use of the voltage source. The clamp diodes provide voltage-clamped signals todrive the synchronous rectifiers.
