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
電磁兼容中有一項測試叫作傳導發(fā)射(Conducted Emission,CE),也被稱為傳導騷擾,是指電子、電氣設備或系統(tǒng)內部的電壓或電流通過信號線、電源線或地線傳輸出去而成為其他電子、電氣設備或系統(tǒng)干擾源的一種電磁現象。(剩余2569字)
