Abstract
A DC/DC converter includes first and second bridges comprising a plurality of switch elements and a plurality of coupling capacitors. Each coupling capacitor couples one of the switch elements of the first bridge to one of the switch elements of the second bridge. The first and second bridges are connected to a transformer comprising a first primary winding, a second primary winding, and a secondary winding. A coupled inductor comprises first and second inductors and is connected to the transformer so that the first and second primary windings are inductively coupled through the coupled inductor.
