Abstract: An electronic power converter (204) is configured to receive power from a power source (202). The power operates at a switching frequency. The electronic power converter includes a resonant tank circuit (206) operatively connected to the power converter. The resonant tank circuit operates at a tank resonant frequency. The electronic power converter includes a controller (208) operatively connected to the resonant tank circuit. The electronic power converter further includes a variable inductor (300) operatively connected to the resonant tank circuit. The variable inductor is configured to modify the tank resonant frequency to match the switching frequency within a predetermined margin.

Abstract: Systems and methods for using parasitic capacitance of a transformer (206) as an element in a resonant converter are provided. Aspects include determining a parasitic capacitance associated with a transformer, determining a resonant circuit (204)configuration based at least in part on the parasitic capacitance associated with the transformer, and providing a resonant converter comprising the resonant circuit and the transformer.
