Abstract
An electronic power converter is configured to receive power from a power source. The power operates at a switching frequency. The electronic power converter includes a resonant tank circuit operatively connected to the power converter. The resonant tank circuit operates at a tank resonant frequency. The electronic power converter includes a controller operatively connected to the resonant tank circuit. The electronic power converter further includes a variable inductor 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.
