摘要
继电器是电子设备中的一个非常重要的干扰源,在其触点断开和闭合的瞬间产生的瞬态电压会引起严重的电磁辐射干扰。文章通过一例继电器电磁干扰的诊断分析说明了继电器电磁干扰的机理,提出了诊断这种干扰的试验方法和有效的干扰抑制措施。
Relay is one of the main EMI sources in electronic equipments. Serious electromagnetic interference is caused by transient voltage that occurs when its switch turned on and off. In this paper, the principle of EMI caused by relay is described through an EMI test analysis of a relay, and the testing technique for diagnosing interference and effective suppression methods are presented.
