Single current sensor operation with fixed sampling points using a common-mode voltage reduction PWM technique

A method is proposed for reconstructing AC currents with a single DC side current sensor in three-phase AC motor drive system. The method is based on a common-mode voltage (CMV) reduction PWM technique called LuPWM, which eliminates most of the invalid regions for current reconstruction both around...
