A Novel Simulation Model for Common-Mode Inductors Based on Permeance-Capacitance Analogy

This paper proposes a novel simulation model for common-mode inductors. The proposed model is able to capture the frequency dependency of complex permeability and leakage inductance based on an electric circuit with a gyrator. Electric components such as winding stray capacitance are modeled separately. The proposed model can simultaneously analyze filter inductor impedance with respect to differential-mode and common-mode.
