Abstract

A power converter includes a transformer, a primary switch, an auxiliary switch, first and second resonance capacitors, and a secondary side rectification means A switch mode power supply is formed to use reflected voltage and parasitic capacitance as an energy source for a transformer resonance The auxiliary switch effectively exchanges energy between the primary inductance of the transformer and the first and second resonant capacitors The auxiliary switch effectively switches the transformer resonance between two distinct frequencies In one embodiment of the invention, the power converter can be, but is not limited to, a flyback converter and further includes a comparator and a driver The dnver is configured to drive the auxiliary switch based on the output state of the comparator The resonant nature of the converter provides zero voltage (ZVS) for the pnmary switch as well as for the auxiliary switch
