Simulation
摘要 运用MATLAB仿真软件分析了分立元件各寄生参数对分压系数、隔离度、串扰及阻抗的影响。通过分析接地和金属板的两种基本串扰形式,建立了人工电源网络(AMN)相应的等效电路模型,并用MATLAB仿真软件分析了两种模型下的寄生参数对AMN隔离度、阻抗的影响。结果表明:寄生参数及其耦合关系对AMN测量有较大影响。

Abstract The voltage division factor, isolation, crosstalk and impedance of artificial
mains network (AMN) are analyzed by employing MATLAB simulation. The equivalent
circuit of AMN is proposed based on two basic crosstalk models which are grounding
and the metal plate. Furthermore, according to the two models, the isolation and
impedance of AMN are also investigated by MATLAB. The results show that the test
using AMN is seriously affected by the parasitic parameters and their coupling status
between AMN and ground/ metal plate.
