一阶电路三要素法推广应用的研究

Researches on the application of three-element method for first order circuit

目前教材及相关文献介绍的一阶电路三要素法具有局限性,不能用其直接求出任意激励下的一阶电路全响应.从一阶电路微分方程出发,给出了任意激励下一阶电路三要素法的一般表达式,该表达式具有很强的概括能力和其它方法无法比拟的优点,并举例说明典型激励下一阶电路的全响应.

The three-element method for the first order circuit in textbooks and references has some (weaknesses:) by using it the full response for the first order circuit under arbitrary excitation can not be solved. General expression of the three-element method for the first order circuit under arbitrary excitation was derived from its differential equation, and it has more advantages than other methods. At the same time, this paper illustrated with examples the application of the full response for the first order circuit under a typical excitation.
