摘要金属导体地电流通过地回路公共阻抗在不同电气电子设备之间形成电磁干扰,严重时甚至使敏感设备无法正常工作。然而,地回路公共阻抗在不同回路中表现出不同的阻抗值,因此必须对邻近效应情况下的金属导体进行深入研究。本文利用PEEC方法对邻近效应时的金属导体进行了建模,得到了系统矩阵方程。然后,将简化等效电路和原始电路中导体与导线电流分别进行复频率s幂级数展开匹配,得到了电阻、电感及互感参数,给出了同时考虑趋肤效应与邻近效应时独立于频率之外的简化等效电路模型,并通过算例验证了参数提取方法的正确性。

Abstract：The Electromagnetic Interference(EMI) among various electrical and electronic equipment can be formed by ground current in metal plate via common ground loop impedance. It will even result in the malfunction of the sensitive devices under some serious conditions. However, the common impedance has different value in different loops. Therefore, it is necessary to analyze and study a conductor with proximity. This paper adopts partial element equivalent circuit(PEEC) to model a conductor with proximity, and to obtain the system matrix equation. After matching the corresponding current coefficients expanded in powers of s between the reduced circuit and the original circuit, the resistance, inductance, and mutual inductances of the reduced circuit are provided. And then, the reduced equivalent circuit model regarding of skin and proximity effects is presented independent of frequency. Furthermore, the mutual inductance between the reduced branches and the proximity wires are obtained, which is validated by examples.

Key words： Electromagnetic compatibility(EMC) moment matching method proximity effect extraction of mutual inductance parameters reduced equivalent circuit
