伴随网络法在线性电路瞬态分析中的应用

Accompanying network application in linearity circuit transient analysis

本文以伴随网络法为基础,以MATLAB软件为平台,探索出一种对线性电路进行瞬态分析的新方法。该分析方法简便,结果清晰直观。新方法从建立电路方程伊始,就设法避开微分方程,利用伴随网络法将动态电路的过渡过程划分为若干时间间隔Δt,将动态元件L,C用相应的离散模型来取代,经过代换的电路称为原电路的伴随网络。对于每一个时间间隔Δt而言,在伴随网络中不含动态元件,因而可将瞬态电路的分析归结为一系列不同离散时刻下电阻网络的稳态分析。

This paper,taking accompanying network as the basis and the MATLAB software as platform, probes out one kind of new approach carrying out the transient analysis on linearity circuit. The new method is simple and convenient. Complying with the building - up circuit equation beginning, it tries to avoid differential equation right away, and makes use of accompanying network following At transient process divided for some periods, and comes to substitute development component L, C with corresponding discrete model, by that the substituting circuit is called the accompanying network . To every period At, there is no development component in the accompanying network, so the transient analysis of this linearity circuit can be divided into a series of steady state analysis of resistance network.
