“…A model for a UR-core CMI that takes the inductor CM voltage as an input and predicts the inductor CM current is presented in [4]. This model involves the use of a time-domain hysteresis model set forth in [7] to conduct magnetic analysis. However, the work in [7] has never been validated for complex PWM excitations such as are encountered in power converters and the work in [4] has never been experimentally validated at all.…”

Common-mode inductors are generally designed so that their operation is in the magnetically linear region of the core material. Very few works consider magnetic hysteresis in the core in terms of the common-mode current waveform. This work validates one such magnetic model and enhances it by including the common-mode current due to the inductor's parasitic capacitance. This work establishes the considerable impact of hysteresis and parasitic capacitance on the ability of a commonmode inductor to reduce common-mode current. 1 Index terms -Common-mode, common-mode inductor, magnetic hysteresis, common-mode capacitance.
