Patent ID: 8035996

Claim:
A full-bridge power converter providing DC output power, the power converter comprising: an input port to receive a source of power to be converted; an output port to provide DC output power; a bridge circuit having a first switch and a second switch coupled in series at a first node, and a third switch and a fourth switch coupled in series at a second node, the series combination of the first and second switches being coupled in parallel with the input port, the series combination of the third and fourth switches being coupled in parallel with the input port; a transformer having a primary winding coupled to the first and second nodes, and at least one secondary winding; a current rectifying circuit coupled to the at least one secondary winding of the transformer; and an output inductor coupled between the rectifying circuit and the output port; and wherein each of the switches is switched between alternating conducting and non-conducting states a plurality of times, wherein the first and second switches are switched so that they are not in conducting states at the same time, wherein the third and fourth switches are switched so that they are not in conducting states at the same time, wherein the second and fourth switches are switched so that they are not in conducting states at the same time, and wherein the first and third switches are switched so they are in conducting states at the same time during a plurality of time durations.
