摘要
本文对当电容电压发生跃变时,电容电流中含有冲激分量,作了必要的剖析,阐述了存在问题的关键,并给确定电容电流完整表达式的统一方法-“一次性”计算法。
As a capacitor lumps in voltage,its current must contain impulse components.It is important how to caculate these impulse components and how to define the capacitive cur- rent as a complete expression in dynamical circuit analysis.At present,there is no unified method of giving a complete expression of capacitive current as voltage jumps across a capacitor in the works concerned.Although some articles have given some caeulating meth- ods through discussion,certain problems still exist.In this article,the author describes the key to the problems existing through necessary analysis,and gives a unified method of de- fining the capacitive current complete expression——'once—through'caculating method.
