Abstract
A resonant converter includes first and second input terminals for applying an input voltage and first and second output terminals for providing an output voltage. A transformer includes a primary winding and a secondary winding, where both the primary winding and the secondary winding have a first and a second terminal. A series resonant circuit includes a capacitive element and the primary winding of the transformer. A switching circuit is connected between the input terminals and the series resonant circuit. A rectifier circuit is connected between the secondary winding and the output terminals. A clamping circuit is connected between one of the first and second terminals of the primary winding and the input terminals.
