摘要
对方波激励下串联LC电路进行了研究,讨论了方波周期与LC电路振荡周期成不同倍数时的电容电压和电感电流的变化规律。首先用二阶电路暂态过程分析的方法对方波激励下串联LC电路进行了理论分析,再利用Orcad/Pspice仿真软件对理论分析结果进行仿真验证。通过这种先理论分析再仿真验证的方式使学生加深对二阶LC电路暂态过程分析的理解。
The series LC circuit is studied under the square wave excitation . This paper has discussed the change rule of Uc and iL under the condition of the square wave period and oscillation period which have different multiples .Firstly ,this paper uses the method for analyzing the second order circuit transient process to calculate the output under the square wave excitation .Then ,the analysis result is verified by Orcad/Pspice . By the way from the theoretical analysis to the simulation verification , it makes students have deeper understanding for the transient analysis of the second order circuit .
