Abstract:
In this paper,according to the EMC problem of medical electronic equipment,the generation mechanism of the conducted EMI noise is analyzed,which includes four kinds of situations,such as transient current,bad grounding,crosstalk and capacity coupling. This paper also puts forward the corresponding noise suppression scheme according to the formation mechanism of the conduction of EMI noise,including power decoupling,filter design,the ferrite core and shielding,and its validity and practicability are verified by two engineering examples.
