PSPICE仿真分析与二阶动态电路教学法研究

Research on teaching method of second order dynamic circuit based on PSPICE simulation analysis

通过对二阶动态电路教学过程的分析,提出了将仿真分析与多媒体课件及板书相结合的教学方法。给出PSPICE软件的常用功能及进行电路仿真分析的基本步骤。以PSPICE仿真在二阶动态电路时域分析辅助教学实例,展示了RLC串联二阶电路在欠阻尼、临界阻尼和过阻尼情况下零输入、零状态和全响应曲线。实践证明,在课堂教学中引入仿真分析,能够促进学生理解电路及元件特性,全面掌握知识,提高教学效果。

By analysis the teaching procedure of the second-order dynamic circuits,this paper brought out a teaching method combined simulation analysis with multimedia courseware and blackboard-writing. and discussed briefly the common functions of the software PSPICE and the basic steps of circuit simulation.Took the time domain analysis of the second-order dynamic circuits by using PSPICE as an example to demonstrate the zero input,zero state and full-response curve of the immediate output of the second-order series RLC circuit under the the damped,critically damped and over damped circumstances.Practice has proved that application of simulation in class can promote students to understand the circuit and components characteristics,fully grasp the knowledge,and improve teaching effectiveness.
