To reduce the volume and weight of differential-mode (DM) inductors, the leakage inductance of a toroidal common-mode (CM) choke is always used as a partial DM inductance. However, the accurate prediction of the leakage inductance of CM chokes through an analytical model is difficult, making the determination of remaining DM inductance difficult. This paper proposes a modeling method with the analogy between reluctances (or magnetic fields) and capacitances (or capacitive fields).
