Claim Text:
1. A power converter comprising: a transformer having a primary winding and a secondary winding; a primary side circuit coupled to the primary winding, the primary side circuit configured to receive an input voltage and to switch the input voltage across the primary winding of the transformer; and a secondary side circuit coupled to the secondary winding and configured to output a substantially direct current (DC) output, the secondary side circuit comprising an active forward mode rectifier and an output; wherein the transformer secondary winding includes a first end, a second end, and a center tap; wherein the active forward mode rectifier is coupled to the first end, the second end, and the center tap; wherein the active forward mode rectifier comprises a first rectifier diode coupled to the first end of the secondary winding, a second rectifier diode coupled to the second end of the secondary winding, and a first clamp diode coupled to the center tap; wherein the active forward mode rectifier comprises a third rectifier diode coupled to the first end of the secondary winding, a fourth rectifier diode coupled to the second end of the secondary winding, and a second free-wheeling diode coupled to the center tap; and wherein the secondary side circuit further comprises a first output inductor having a first end and a second end and a second output inductor having a first end and a second end, and wherein the first rectifier diode, the second rectifier diode, and the first clamp diode are coupled to the first end of the first output inductor, and the third rectifier diode, the fourth rectifier diode, and the second clamp diode are coupled to the first end of the second output inductor.
