摘要
目前采用仿真软件来分析电路时,一般在已知电路参数的情况下求数值解,或者得到电路仿真后的动态响应波形。而在电路的分析计算中,有时往往希望得到电路中待求量的解析解,方便进一步数学推导和理论分析计算。本文利用Matlab强大的符号处理能力进行电路的符号运算,并得到电路的解析表达式,为电路分析提供了一个有效的辅助手段。
It is most common that circuit analysis normally gets the numerical result or the dynamic response wave after simulation by the simulation software with all the parameters of the circuit components havinge assigned values. But in the circuit analysis and calculation, we need to get the analytical solution of the demanded circuitvariable , in order to deduce or get theoretical analysis more conveniently. This paper implements the symbol analysis of circuit and obtains analytical expression with the powerful symbol operation of the Matlab, provides an efficient assistant method for circuit analysis.
