Abstract :
In this paper a new physically based PSPICE-compatible model for common-mode chokes for the prediction of EMI-filter size and insertion loss is presented. Skin-effect inside the winding and the nonlinear characteristic of core materials can be considered. The model parameters can be obtained from the winding and the core geometry. The accuracy of the model is demonstrated for a typical EMI-filter in a high frequency switched mode power supply
