A d-c to d-c converter utilizing a resonant inductor to neutralize capacitive losses is disclosed. In most high voltage d-c power supplies, a step-up transformer is employed as the conversion element from the low voltage source to the high voltage output. Such transformers exhibit capacitive losses resulting from intra-and inter-winding capacitances. When utilizing a large step-up transformer wherein the turns ratio n=Np/Ns is much less than 1, the capacitive losses result in a sharp decrease in the load to source voltage ratio thereby reducing the power available to the load. The present invention compensates for these losses by providing a resonant inductor which forms, at the operating frequency of the transformer, a resonant circuit with the equivalent Thevenin capacitive reactance as viewed from the primary side of the transformer resulting from these losses.
