| 摘 要： | 分析了由电气设备的静电放电引起的电磁干扰(EMI)的机理,利用小波分析的多分辨特性,对叠加噪声后的电磁干扰信号进行了时频分解,准确判断出放电干扰发生的时刻,提取出放电信号,从而实现了对静电放电的电磁兼容(EMC)分析,为进一步抑制干扰源提供了依据。

| Abstract: | This paper analyzes the mechanism of electromagnetic interference (EMI) caused by static discharge of electrical equipment. The interference signal superposed by noise is decomposed in frequency domain by using multi-resolution wavelet. Then, the discharge signal is extracted so that electromagnetic compatibility (EMC) analysis of static discharge is realized and the basis for further controlling interference source is provied. |
