1. A step wave power converter comprising:

  • a processor configured to;

    operate bridge circuits;

    modulate at least one direct current DC input with the bridge circuits to form multiple individual voltage steps of a step wave Alternating Current (AC) output;

    associate different carrier waves with the bridge circuits that have frequencies that are multiple times greater than a frequency of a reference waveform and are independent of the voltage steps of the AC output formed by the bridge circuits; and

    modulate with the bridge circuit variable width pulses onto the voltage steps of the AC output according to a comparison of the carrier waves with different points in the reference waveform.
