动态电路初始值的研究

Study on the Initial Value in the Dynamic Circuit

储能元件初始值的确定对研究动态电路的分析至关重要。通过对四个典型的RC常态电路、病态电路的电容初始电压及冲激电流的分析,系统、深入地探讨了RC常态电路、病态电路在有界电源激励下的初始值的确定,并得出在病态电路中的电容电流必是冲激电流的重要结论和三种RC病态电路电容电压初始值的求解方法。从理论上更深入了对RC病态电路初始值乃至电路暂态响应的认识,解决了RC病态电路初始值求解难的问题。

The solution to the initial value is very important for analyzing the dynamic circuit. This paper describes the initial value of RC normal or morbid circuit by bounded source stimulus amply and thoroughly through analyzing capacitor initial voltage and impulse current of four typical RC normal and morbid circuits, moreover, the significant conclusion is drawn that capacity current must be impulse current. Capacitor initial voltage solution method of three RC morbid circuits could be gained. It enhances the cognition for RC morbid circuit initial value and transient response in theory,and solves the difficulty of gaining the initial value in RC morbid circuit.
