【摘要】本文以医用显示器作为测试设备,利用控制单一变量的方法,分析了在低频段时线缆的摆放、长短等因素对传导发射试验的影响。通过对比发现,线缆采用短线、去耦方式布置时,对公共电网的干扰更大。

Abstract: This article uses medical displays as testing equipment and uses the method of controlling a single variable to analyze the influence of factors such as cable placement and length on conducted emission tests in the low frequency range. Through comparison, it is found that the interference of cables on the mains network is greater when arranged in short lines and decoupling methods.
Keywords: electromagnetic compatibility; conducted emissions; cables
0引言
电磁兼容中有一项测试叫作传导发射(Conducted Emission,CE),也被称为传导骚扰,是指电子、电气设备或系统内部的电压或电流通过信号线、电源线或地线传输出去而成为其他电子、电气设备或系统干扰源的一种电磁现象。(剩余2569字)
