Abstract

This paper discusses the suppression of torque ripple using multi-level inverters in motor drives. Because it is possible to improve the output waveforms using multi-level inverters, it is also possible to improve the control performance of motors. In this paper, the multi-level inverters achieve precise motion control, and a theoretical distortion index for multi-level motor drives that takes the control sensitivity into account is proposed. By calculating the distortion index, the optimal equivalent carrier frequency that can minimize torque ripple can be obtained. The validity of the proposed method is confirmed by our experimental results.
