ABSTRACT:
A zero current soft switching power converter (10) is provided in which a link capacitor (20) is coupled between a source switch S.sub.1 and a source switch S.sub.2. The reversal of voltage polarity across link capacitor (20) allows for zero current switching of switches S.sub.1 and S.sub.2.
