| 摘 要： | 在动态电路的时域分析中，若要解出描述电路的微分方程或状态方程，首先必须知道电路的初始状态。可是对含有纯电容回路和纯电感割集的奇异电路，在“换路”瞬间其初始值有可能发生跃变现象，不能用换路定则来求解。文章对此类电路中的初始值进行了详细的分析。通过深入探讨，给出了奇异电路中电容电压和电感电流初始值的确定方法，并给出了几个应用实例。

| Abstract: | In the time domain analysis of dynamic circuit, the initial state must be first known when the differential equation or state equation will be solved. But in the singularity circuits that contain pure capacitance loop and pure inductance cutset, the initial value is possible of jumping phenomenon when switching. The switching law can't be used. In this paper, the initial value of this kind circuit is analyzed in detail. The method for determining the initial value of capacitance voltage and inductance current is studied. At last, some examples are presented. |
