Abstract
A power converter is operative to reduce harmonics at an AC input by controlling its power switching so that a current waveform in a switched inductor is substantially identical to a rectified version of the input AC voltage waveform. The voltage spikes induced by the switching of the inductor into circuitry that includes the leakage inductance of a power transformer are subdued by circuitry that absorbs the initial voltage spike temporarily and then delivers that energy to the output load of the converter.
