1. An inverter, comprising:
a high frequency switching control circuit operatively coupled to a DC power input;
a synchronous-buck circuit controlled by the high frequency switching control circuit to cyclically invert the DC power input; and
a low frequency switching circuit for providing an oscillated output to provide zero voltage switching and zero current switching by driving an output capacitor circuit to discharge on each zero crossing of the low frequency switching circuit.
