摘要
本文根据人工电源网络的原理图,建立了阻抗测量的高频寄生参数模型,并分析了适配器寄生参数以及各独立元件在电路中的作用。通过分析接地和金属板的两种基本串扰形式,建立人工电源网络相应的等效电路模型,运用MATLAB仿真软件仿真分析了两种模型下的寄生参数对阻抗的影响。仿真得到的随频率变化的曲线表明,寄生参数及其耦合关系对阻抗测量有重要影响。
This paper established a high-frequency parasitic impedance measurement model and analyzed the effect of parasitic parameters of adapter and independent components in the circuit according to the schematic of artificial mains network.By analyzing the two basic crosstalk forms ground and the metal plate,the equivalent circuit model of LISN was es-tablished.The effect of two models of parasitic parameters on the impedance was analyzed using MATLAB simulation soft-ware.The simulation results of the frequency curve showed that parasitic and coupling have an important influence on LISN.
