MULTILEVEL ACTIVE INVERTERS AND METHODS OF CONTROLLING MULTILEVEL ACTIVE INVERTERS

摘要

The method of controlling the inverter comprises: generating a neutral phase reference waveform, generating a neutral phase center point compensation waveform using the neutral phase reference waveform, and generating a neutral phase compensation duty cycle waveform using the neutral phase center point compensation waveform It includes the step of making. Neutral phase switch command signals are generated for switches of the neutral phase of the inverter using the neutral phase compensation duty cycle waveform. Also described are inverters and computer program products.
