Abstract: A DC-to-DC converter having a transformer with a primary and a tapped secondary, two serial output filter inductors connected parallel with the secondary, a center output filter inductor connected between the secondary tap and serial output inductors, two serially connected switches connected in parallel with the two output inductors for receiving a signal to control operation of the switches during steady state and an output load connected between the serial connection of the serial output inductors and serial switching devices. The transformer primary side connected with double-ended primary-side topologies. The transformer secondary and output filers configured to form a current tripler rectifier, current quadtupler rectifier or current N-tuper rectifier.

Abstract: A transformer includes a primary winding, a secondary winding, and a transformer core having a first leg, a second leg and a third leg. The second leg is positioned between the first leg and the third leg, and the primary winding is wound around the first leg, the second leg and the third leg. A power converter includes a primary winding, a secondary winding, a rectifier coupled to the secondary winding, and a transformer core having a first leg, a second leg and a third leg. The second leg is positioned between the first leg and the third leg, and the primary winding is wound around the first leg, the second leg and the third leg.
