摘要
从建立复频域电路定律和电路模型入手,把时域电路通过拉普拉斯变换为复频域电路模型,建立简单的代数方程,利用拉普拉斯反演,求得动态过程中的电路响应.这一方法免除了经典的解微分方程,求初始值的复杂过程,更重要的是解决了换路定律和基尔霍夫定律之间的矛盾,从而使电路动态过程的分析和解决变得简单快捷.
Starting with complex frequency field circuit law and model,based on Laplace transform,time field circuit model changed into complex frequency field circuit model,established simple algebraic equation,and used Laplace inversion,obstained the circuit response of dynamic process.The method avoid complex calculation of solution differential equation and seeking the initial value.Above all,the method solve the contradiction between the law of switching and Kirchhoff＇s law.Thus making the analysis and solution of circuit dynamic process becomes easy.
