| Abstract: | Relay is one of the main EMI sources in electronic equipments.Serious electromagnetic in- terference 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 test- ing technique for diagnosing interference and effective suppression methods are presented. |
