浅析冲激源作用下的电容短路特性与电感开路特性

A Study of short-circuit-Characteristic of Capacitor and open-circuit-Characteristic of Inductor Under the Excitation of an Impulse Source

在冲激源作用瞬间,将电容视为短路、将电感视为开路的观点,虽已被广泛接受,然而这一观点却与传统电路理论中关于“短路”和”开路”的概念不相符合。针对这一情况,本文给出了适用范围更广的”短路”与”开路”的定义,进而分析了几种典型的 RC 和 RL 电路在冲激源作用瞬间电容的短路特性和电感的开路特性。

It is recognizied to consider the capacitor as a short circuit and the inductor as an open circuit at the instant when the impulse source acts on a circuit.Althou- gh this point of view has been widely adopted,it does not agree with the con- cept of“Short Circuit”and“Open Circuit”interpreted by traditional circuit the- ory.This paper gives a new definition to“Short Circuit”and“Open Circuit” and proceeds to analyse the short-circuit-characteristic of capacitor and open-cir- cuit-characteristic of inductor in some typical RC and RL circuit excited by impulse Source.
