Abstract
A circuit, including first and second electronic switches cascaded in a current flow line between an input node and ground, a transformer having a primary winding coupled across the second electronic switch, and a capacitor coupled across the secondary winding, is operated by making the first and second electronic switches conductive and non-conductive in a sequence of phases including an energy storage phase, with current flow in the primary winding and no current flow in the secondary winding, and subsequently a concurrent conduction phase, with current flow in both the primary and secondary windings of the transformer. The circuit is operable in a first mode, wherein the concurrent conduction phase is maintained over a first off time of the first switch, and in a second mode, wherein the concurrent conduction phase is maintained over a second off time of the first switch shorter than the first off time.
