1. A method of controlling an inverter, comprising:

  • generating a neutral-phase reference waveform;

    generating a neutral-phase midpoint compensation waveform using the neutral-phase reference waveform;

    generating a neutral-phase compensated duty cycle waveform using the neutral-phase midpoint compensation waveform; and

    generating neutral-phase switch command signals for switches of a neutral-phase of the inverter using the neutral-phase compensated duty cycle waveform.
