摘要
电磁干扰问题是现代通信装备长期存在的顽疾,主要有辐射和传导两种方式产生。分析干扰问题需要从干扰源、耦合通道和敏感体3个方面考虑:准确地分析判断干扰源、合理有效地切断耦合通道和正确有效地保护敏感体。这是解决EMI问题的有效方法。文章主要介绍了一种典型的电磁干扰,并结合实例给出了相应的低成本解决方法。
Electromagnetic interference is a persistent disease of modern communication equipment,which is mainly produced by radiation and conduction.Analysis of interference problem needs to be considered from three aspects:interference source,coupling channel and sensitive body:accurate analysis and judgment of interference source,reasonable and effective cut off of coupling channel and correct and effective protection of sensitive body are effective methods to solve EMI problem.This paper mainly introduces a typical electromagnetic interference,and gives the corresponding low-cost solution with examples.
