Abstract:

Common mode chokes (CMCs) are key components in electromagnetic interference (EMI) filters, and accurate modeling of these components is critical for filter design and EMI noise simulation. This article proposes a behavioral model and parameter extraction technique for characterizing three-phase four-wire common mode chokes (4W-CMCs). The proposed model considers the inductance nonlinearity caused by the nonlinear permeability of manganese-zinc ferrite and nanocrystalline magnetic materials, as well as the asymmetry and local symmetry in the winding distribution of 4W-CMCs. The parameters for the common mode and differential mode (DM) models are extracted using a parameter extraction program and a simple equation-based method, respectively. For the DM model parameter extraction, this article proposes a measurement method that utilizes the local symmetry of 4W-CMCs. The equivalent circuit of this measurement method decouples the interwinding capacitance (C-W) from the DM inductance parallel capacitance (C-D) by transforming two-port network parameters, greatly simplifying the parameter extraction process. The accuracy of the model and the effectiveness of the method are validated through experiments using several 4W-CMCs with manganese-zinc ferrite and nanocrystalline magnetic cores.
