IEEE Std C63.13-1991 工业用电源线电磁干扰滤波器的应用和评定指南

this guide is intended to provide a basic understanding of the application, evaluation, and safety considerations of electromagnetic interference (EMI) power-line filters used in both ac and dc applications. It includes a basic description of the construction of an EMI power-line filter and its functions in providing suppression of conducted noise. In addition, it provides explanations of why seemingly identical filters may not give the same performance in a particular application. Finally, proper installation of these filters in equipment is discussed.
