EMC为Electromagnetic Compatibility一词的缩写,国内常把它译为电磁兼容,这是一门正在发展的新兴学科。大家知道,在一个电系统中,只要把两个以上的很小元件放在同一环境中就会产生电磁干扰,而两台以上的设备在同一环境中就更易出现电磁干扰。如何使这些在共同环境中的设备能执行各自的正常功能,就是电磁兼容所要研究解决的主要内容,但由于这一学科的范围仍在日益扩大,现在也不只限于电气及电子设备本身,还涉及到电磁污染、 EMC is the abbreviation of Electromagnetic Compatibility, which is often translated as Electromagnetic Compatibility (EMC) in China. This is an emerging emerging subject. We all know that in an electrical system, as long as two or more small components on the same environment will have electromagnetic interference, and more than two devices in the same environment is more prone to electromagnetic interference. How to make these devices in a common environment perform their normal functions is the main content to be studied and solved by EMC. However, as the scope of this discipline is still growing, it is not limited to the electrical and electronic equipment itself, but also involves To electromagnetic pollution,
