| 摘 要： | 对时域有限差分(FDTD)法应用于不等长多导体传输线端接非线性负载的情况进行了介绍.首先给出了多导体传输线电报方程和差分公式;然后介绍了不等长传输线的仿真模型;在此基础上,最后通过建立端接非线性负载的不等长多导体传输线模型,对该情况下传输线两端的电压响应进行了分析.数值仿真结果说明了FDTD法解决此类问题的正确性和有效性,为不等长传输线瞬态分析的进一步研究打下了基础.

| Abstract: | The Finite-Difference Time-Domain(FDTD)method for unequal length multiconductor transmission lines(MTL)with nonlinear loads is presented.Firstly,the MTL equations and their difference equations are introduced.Then,simulation model for unequal length MTL is discussed.Based on this,the transmission line's voltage response is analysed through building model for MTL with nonlinear loads.The simulation results show that the proposed method is correct and efficient.The work of this paper lays the foundation for f... |
