TLDR
A behavioural model for performance evaluation of a common mode choke (CMC) is proposed and combines an accurate model of the complex permeability, of the saturation, of leakage inductances and of parasitic capacitances.Abstract:
A behavioural model for performance evaluation of a common mode choke (CMC) is proposed: the topology and methods used to model the different properties of the CMC are presented. It combines an accurate model of the complex permeability, of the saturation, of leakage inductances and of parasitic capacitances. Inputs needed from the designer are measured values of currents, voltages and impedance of the actual system, and parameters available in literature and/or from manufacturers for the modelled CMC. The behavioural model is essential in simulation of EMI effects.read more

Analysis of CM Volt-Second Influence on CM Inductor Saturation and Design for Input EMI Filters in Three-Phase DC-Fed Motor Drive Systems
TL;DR: In this article, two new mechanisms for common-mode choke saturation due to CM voltage were proposed, and these mechanisms were verified in an experiment with a motor drive system with high CM voltage and comparably higher stray grounding capacitance.

A Modal Model of Common-Mode Chokes for Conducted Interference Prediction

TL;DR: In this paper, a mathematical model of the hysteresis mechanisms in ferromagnets is presented based on existing ideas of domain wall motion including both bending and translation, which gives rise to a frictional force opposing the movement of domain walls.

TL;DR: In this paper, the contribution of domain-wall and natural resonance to the permeability spectra was estimated by the numerical fitting of actual measurement data to a simple formula, where the frequency dispersion type of each component, relaxation or resonance, was estimated from one of the fitting parameters, damping factor.
