A New Space Vector Modulation Strategy for Gammon Mode Voltage Reduction

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 coimmon mode current produced by the inverter, active filtering is proven to greatly reduce common mode conducted emissions due to the modulation of the converter. A new space vector modulation strategy is presented for common mode EM1 reduction in three and four phase converters.
