摘要
复杂通用电路的分析需要求解一组多变量方程或一个变量的高阶微分方程,手工计算难度大。为方便运算采用结点电压法和拉普拉斯变换法在复频域进行分析来解决此问题。在简化运算的同时,利用Matlab等数学软件通过计算机编程求解方程,可以大大减少计算量;通过Matlab进行人机交互界面设计将电路中各结点电压波形可视化,方便、直观地得到电路中各元件的电压,展现电路从暂态到稳态的运行状况,使得分析计算更简便。
Since the analysis of complex general-purpose circuits usually requires to solve a set of multivariable equations or higher-order differential equations of one variable,it is often difficult to calculate by hand.In order to facilitate the operation,the node voltage method and the Laplace transform method are used to analyze the complex frequency domain to solve this problem.While simplifying the operation,using mathematical software such as Matlab to solve the equation through computer programming can greatly reduce the amount of calculation.Finally,the human-computer interaction interface design is carried out through Matlab to visualize the voltage waveform of each node in the circuit,and the voltage of each element in the circuit can be obtained conveniently and intuitively,which shows the operation status of the circuit from transient to steady state,and makes the analysis and calculation easier.
