摘要
讨论了电力电子系统电磁干扰的抑制措施,重点阐述了不同接地方式对共模(CM)电磁干扰抑制的影响和EMI滤波器特性及其设计的方法步骤,分析了电力电子系统电磁干扰的有源抑制的方法原理,指出了有源滤波是电力电子系统电磁兼容的一个重要研究方向.
The influences of different kinds of earthing on the suppression of common mode (CM) electromagnetism interference (EMI) are elaborated, together with the characteristics of EMI filters and their design methods. Based on the analysis of the methods and principles of active suppression of EMI in power electronics systems, it is pointed out that active power filter is a promising research field in electromagnetism compatibility (EMC).
