| 摘 要： | 分析了由电气设备静电放电引起的电磁干扰机理,并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,提取了放电信号,从而完成了对静电放电的电磁兼容分析,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 added with noise is decomposed into different frequency range using multi-resolution wavelet. The discharge signal is extracted and the time at which discharge interference happens is exactly estimated. As a result, the electromagnetic compatibility (EMC) analysis of static discharge is carried out, that can provide basis for the further control of interference sources. |
