运用多导体传输线理论为均匀及非均匀介质中的传输线耦合情况建立相应的等效电路模型,借助Matlab软件对PCB板上三导体传输线的线间串扰进行仿真计算.首先分析终端为匹配负载的情况下,主串回路的电压变化对串扰电压的影响,然后分析了终端接电阻、电抗、阻抗三种不同的终端负载情况下串扰电压的变化.结果表明,串扰电压随主串回路电压的增加而增加,且匹配的电阻值能够减小串扰电压,容性负载对串扰电压的影响要比感性负载大.

This paper establishes the mode of corresponding equivalent circuit for transmission line coupling inhomogeneous and inhomogeneous media based on the theory of multi—conductor transmission line，simulatesand calculates the crosstalk among three conductor transmission lines on the PCB board using Matlab software．Firstly，the paper analyzes the voltage change of main loop of string on the impact of crosstalk voltage in thecase of the terminal is matched load．Then we analyze the change of the crosstalk voltages in the terminal ac—cess resistance，terminal access reactance，terminal access impedance of the three different terminal load cases，and gets the appropriate conclusions．The results show that crosstalk voltage as the main string loop voltage increases，matched resistance value can reduce the erosstalk voltage，and capacitive load is more significant than inductive load on the impact of crosstalk voltage．
