Pulse-Width-Modulation (PWM) control algorithms are commonly used in AC motors. However, in some cases the PWM itself may cause the bearing failures in electric drives, for which the common-mode voltage and current could be accounted. To reduce the common-mode voltage (CMV), both passive and active...
