共模扼流圈是许多电磁干扰滤波器的重要组成部分，其建模是保证滤波器设计最优的关键。许多寄生效应被纳入电路或行为模型，以考虑元件对传递函数的复杂影响。已进行的可设计参数的调查，在创建受控设置归因于寄生在测试台架的困难。因此，本文的目标是克服这些困难，同时仍然确保基于物理的方法，允许虚拟原型。建立了全波三维模型，同时考虑了岩心材料的复磁导率。最后，可以使用多/混合模式的S-参数的调查得出的参数对电路/行为模型的影响。优势包括设计优化加速，从数小时的试错到数分钟，具体取决于仿真的复杂性。
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.
