Fourth-Arm Common-Mode Voltage Mitigation

Autor: Adrian Zuckerberger, Kfir J. Dagan, Raul Rabinovici

Publikováno v: IEEE Transactions on Power Electronics. 31:1401-1407

The adverse effect of common-mode voltage (CMV) in pulse-width modulation inverters is widely acknowledged. Various approaches for mitigating CMV effect in PWM inverters have been proposed in the literature but they either show limited effect or impa
