动态电路分析是电路原理教学中的重点和难点内容之一。以脉冲分压电路在换路后的响应求解这一问题为例,分析了课堂教学过程中学生在电路阶数、响应形式以及求解方法等方面容易发生理解错误的原因,并采用时域、复频域两种分析方法推导获得该电路动态响应的表达式,最后通过电路仿真软件进行教学实验演示,获得了较好的课堂教学效果。
Dynamic circuit analysis is one of the most important and difficult issues in the teaching of circuit theory. Taking the problem of resolving the response of pulse voltage divider circuit after circuit change, this paper analyzes the reasons that students are prone to misunderstanding in circuit order, response form and solution method in classroom teaching. Domain two analytical methods to derive the expression of the dynamic response of the circuit, and finally through the circuit simulation software for teaching demonstration, access to better classroom teaching.
