二端网络等效电阻的快速求解方法

Fast Calculation Method of Two-terminal Network Equivalent Resistance

二端网络是电子电路系统的有机组成部分,而分析其等效电阻是理论教学中的重要内容。这部分教学的难点在于含有受控源的二端网络等效电阻的分析。传统的求解需要通过外加电源等方法,列出方程组进行求解,过程较为复杂。本文深入分析了受控源电路的特征,以折算系数的方式可直接给出等效电阻,较大程度地简化了分析过程。文章对电路理论和模拟电子技术的教学有一定的指导作用。

The two-terminal network is a necessary component of the electronic circuit system,and the analysis of its equivalent resistance is an important part of the teaching.If the network contains controlled power,the analysis process will become more difficult.The traditional method is too complex,because the equations need to be solved.In this paper,the characteristics of the controlled source circuit are analyzed.The equivalent resistance can be given directly by the conversion coefficient,and the analysis process is simplified to a great extent.The article has a certain guiding role on the teaching of circuit theory and analog electronic technology.
