要約(英語): In this paper, an output voltage accuracy improvement method for an asynchronous PWM inverter is proposed. This method is suitable for control conditions where the ratio of the carrier frequency to output voltage frequency is lower than 9. In such a situation, the inverter output voltage contains disturbance voltage composed of the beat component. The proposed method suppresses the disturbance voltage by adding a compensation term to the voltage command. The details regarding an analytic derivation method of the above compensation term is written in this paper. The validity of the proposed method is confirmed by computer simulation and experiment.
