ABSTRACT:
For use in a power converter having first and second output diodes coupled to a secondary winding of an isolation transformer and first and second output inductors, coupled to the first and second output diodes, respectively, and an output derived from the first and second output inductors and a center tap of the secondary winding, a circuit for, and method of allowing the power converter to provide an output current at multiple output voltages. In one embodiment, the circuit includes: (1) a contactor, coupled to a first node between the first output diode and output inductor and a second node between the second output diode and output inductor, that selectively: (1a) closes to create an inter-inductor conductive path to couple the first and second output inductors in parallel and to allow the power converter to operate at a first output voltage and (1b) opens to break the inter-inductor conductive path and to allow the power converter to operate at a second output voltage lower than the first output voltage and (2) first and second conductive paths, coupling the center tap to the first node and the second node, respectively, that provide conductive paths for the output current.
