电磁干扰及电磁兼容检测

Electromagnetic Interference and Electromagnetic Compatibility Detection

电磁兼容性(EMC)是指设备或系统在其电磁环境中符合要求运行,并不对其环境中的任何设备产生无法忍受的电磁干扰的能力。因此,电磁兼容检测是一项非常重要的工作,世界各国都在不断加强电磁兼容技术方面的研究。主要介绍电磁干扰及电磁干扰抑制技术等内容。电磁兼容整改主要是通过综合运用滤波、接地和屏蔽等措施对电磁兼容性改进。通过一整改案例对整改过程进行了分析,对类似产品的整改具有参考作用。

Electromagnetic compatibility （EMC） refers to the equipment or system in its electromagnetic environment to meet the requirements to run and does not produce intolerable electromagnetic interference ability in any of the equipment of their environment. Hence,Electromagnetic compatibility detection is a very important work. Most countries attach important to the research of EMC technology. This article focuses on electromagnetic interference and the suppression technology of EMC,etc.EMC rectification mainly through the integrated use of filtering,grounding,shielding have been implemented to improve electromagnetic compatibility. The processes of rectification are analyzed through a case,which has reference function for the similar products.
