Abstract

As an integral part of many electromagnetic interference filters, modeling the common mode choke adequately is key to ensure an optimal filter design. Many parasitic effects are incorporated into circuit or behavioral models to account for the complex influence of the component on transfer functions. Investigation on the designable parameters has been performed, with difficulties in creating controlled setups attributed to parasitics in the test benches. Therefore, the goal of this paper is to overcome these difficulties while still ensuring a physics-based approach that allows virtual prototyping. The full-wave three-dimensional model is created, while incorporating the complex permeability of the core material. Eventually the effect of parameters on circuit/behavioral models can be derived using a multi/mixed-mode S-parameter investigation. Benefits include design optimization speedups from hours of trial and error to minutes, depending on simulation complexity.
