The high frequency common-mode voltage generated by conventional pulse width modulation (PWM) strategy may lead to bearing electrical corrosion and electro-magnetic interference problems. reduced (RCMV) PWM strategies can reduce the negative effect of without increasing cost hardware. However, existing RCMV-PWM methods are based on asynchronous modulation, which will cause unacceptable harmonic distortion when carrier ratio is too low. This paper presents a hybrid strategy, suppress in wide...
