Abstract A pulsewidth modulation (PWM) technique is proposed for minimizing the RMS torque ripple in inverter-fed induction motor drives subject to a given average switching frequency of the inverter. The proposed PWM technique is a combination of optimal continuous modulation and discontinuous modulation. The proposed technique is evaluated both theoretically as well as experimentally and is compared with well-known PWM techniques. It is shown that the proposed method reduces the RMS torque ripple by about 30% at the rated speed of the motor drive, compared to conventional space vector PWM.
