摘要
提出了利用开路阻抗参数矩阵分析EMI电源滤波器插入损耗的方法。分析共模、差模等效电路的阻抗参数和插入损耗的关系,通过Matlab绘出不同于50Ω测试系统时的插入损耗曲线,并用试验验证了方法的有效性。
A method for insertion loss of EMI power-line filter by analyzing open-circuit impedance parameter is proposed. The insertion loss curve differing from 50Ω insertion loss methods is obtained using Matlab program by analyzing the relation between the impedance of common mode or differential mode noise equivalent circuit and insertion loss. The method is proved by experiment.
