针对电子电路设计受到元器件、实验仪器的制约,介绍了Multisim软件在电子电路设计方面的应用。分析了漏电保护技术的基本原理,研究了基于运算放大电路实现漏电保护的技术,然后通过Multisim仿真软件对基于运算放大电路实现的漏电保护所需要实现的不同电路功能进行了仿真,并且给出了具体的仿真波形。仿真的波形表明采用Multisim仿真软件可以直接通过修改仿真元器件的参数方便地实现漏电保护器的各种功能,可见将Multisim软件应用于漏电保护器产品进行仿真开发是一种切实可行的方法。

Concerning the restriction of components and experimental instrument in electronic circuit design,this thesis introduces the application of Multisim in electronic circuit design,analyzes the basic principle of leakage protection technology,and studies the leakage protection technology based on operational amplification circuit. Then for different circuit functions which need the operational amplification circuit to implement the leakage protection,the simulations of are carried out by the simulation software called Multisim,and special simulation waveforms are obtained. The simulation waveforms show that it is convenient to implement different function of leakage protector by using Multisim to change the parameters of simulation components directly. It can clearly be seen that it is an effective way to implement Multisim in simulation development of leakage protector.
