Abstract:
A power conversion apparatus, comprising:a transformer having primary and secondary windings; a first switching circuit having an input port configured to be coupled across a DC power source and an output port coupled to the primary winding of the transformer; a switch control circuit, operatively associated with the first switching circuit, that causes the first switching circuit to alternately apply first and second polarity voltages to the primary winding; first and second capacitors; an output inductor configured to be coupled to a load; and a second switching circuit coupled to secondary winding, the first and second capacitors and the output inductor and operative to transfer energy to the load from the secondary winding via respective ones of the first capacitor and the second capacitor responsive to respective ones of the application of the first polarity voltage to the primary winding and the application of the second polarity voltage to the primary winding.
