ABSTRACT:
A capacitor isolated electronic power converter includes a direct current power source in series with a first inductor; and a first switch for switching contact with a second inductor in series with the power source return; an output load in series with a third inductor which connects to a second switch for switching contact to a fourth inductor in series with the output load return; the third inductor and second switch for switching connect through a first capacitive coupling to the second inductor; and the fourth inductor and second switch for switching connect through a second capacitive coupling to the first inductor; wherein the first and second capacitive coupling isolate the power source from the output load.
