Abstract
A method of controlling an inverter includes generating a neutral-phase reference waveform, generating a neutral-phase midpoint compensation waveform using the neutral-phase reference waveform, and generating a neutral-phase compensated duty cycle waveform using the neutral-phase midpoint compensation waveform. Neutral-phase switch command signals are generated for switches of a neutral-phase of the inverter using the neutral-phase compensated duty cycle waveform. Inverters and computer program products are also described.
