某类大型复杂机电系统的电磁兼容性研究

Research on the EMC of Some Large-sized Complicated Electro-mechanical System

文章对电磁兼容性(EMC)的概念及电磁干扰的来源进行了介绍,并介绍了某类大型复杂机电系统存在的主要干扰及干扰测量方法,从抑制干扰源、切断传播途径、提高敏感器件的抗干扰性能三个方面阐述了干扰防护措施。

In this paper, the concept of electro magnetic compatibility（EMC） and electromagnetic interference sources are firstly introduced, then based on some large-sized complicated electro-mechanical system, several sources of interference and interferences measurement methods are also introduced. At the end of this paper, interference prevents methods as how to depress interference sources, chop propagation path, increase the anti-interference of sensitive device are illustrated in detail.
