摘要

本文介绍了几种电磁兼容滤波器的建模方法。滤波器的建模可以在电路级或三维场级用全波矩量法(MoM)完成。首先，根据计算或测量的s参数对滤波器的RF分量进行建模。采用三维准静态/准磁性方法计算PCB走线的杂散RLC参数，可以增强电路级模型。在10 kHz至50 MHz的频率范围内，使用不同的方法计算共模和差分模的滤波器衰减，并与测量值进行比较。

Modeling and Validation of the Basic EMC Filter at Different Simulation Levels

In this paper several methodologies for the modelling of EMC filter are presented. Modeling of the filter can be done at the circuit level or at 3D field level with full-wave Method of Moments (MoM). On first step RF components of filter are modeled based on calculated or measured s-parameters. Circuit level model can be enhanced by including stray RLC parameters of the PCB traces calculated with 3D quasi-static/quasi-magnetic approach. Filter attenuation is calculated for common and differential modes using different methods in the frequency range from 10 kHz up to 50 MHz and are compared with measurements.
