5、1/3/11 Conclusion nThe results are basically satisfactory. nMy boss gives me this task in last November and I have finished it in the beginning of this semester. Now what I am doing is the EMI filter. Thats what I want to talk about next. 13 2021/3/11 EMI Filter nElectrical equipments are widely use

6、d in our daily life. They bring great convenience to our life and also make our electromagnetic environment more and more complex. EMI filter is a method to solve the problem of electromagnetic compatibility(电磁兼容). nIn this project, my work is to find a circuit to separate common mode signal and dif
