摘要:
本文针对医疗电子设备的电磁兼容问题,分析了其传导EMI噪声的生成机理,包括瞬态电流、接地不良、串扰和电容耦合4种情况. 本文还根据4种传导EMI噪声生成机理提出了相应的噪声处理方法,包括电源去耦、设计滤波器、采用铁氧体磁环、屏蔽等,并通过两个工程实例验证了其有效性与实用性.
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.
