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. T...
