Enhancement of Common-Mode Power Extraction Through Zero-Sequence Injection in Pulse Width Modulation

Abstract: In motor drive system fed by voltage source inverter (VSI), common-mode voltage (CMV) is commonly present because of pulse width modulation (PWM) techniques. It's proved to be feasible in ...
