1. An interleaved direct current to alternating current power converter apparatus comprising:

  • power modulation means having a plurality of inverters and a bipolar output signal;

    power amplifier means for receiving the bipolar output signal of the power modulation means and for providing an output signal; and

    first error detection means coupled between the output signal of the power amplifier means and the power modulation means for controlling modulation;

    wherein the power modulation means includes control stage means coupled to zero crossing detector means and second error detection means,switching stage means for receiving a plurality of signals from the control stage means;

    high frequency filter stage means coupled to the switching stage means; and

    ,third error detection means coupled to the high frequency filter means and to the control stage means, thereby allowing switching losses and conduction to be evenly distributed among all inverters of the power modulation means.
