Abstract :
In this paper, the impact of the inverter modulation strategy on common mode conducted emissions is addressed. Whereas typically passive filter designs are used to mitigate the common mode current produced by the inverter, active filtering is proven to greatly reduce common mode conducted emissions due to the modulation of the power converter. A new space vector modulation strategy is presented for common mode EMI reduction in three- and four-phase DC/AC power converters
