并联功率模块AC-DC-AC系统的共模EMI噪声分析与抑制

In this article, the common-mode (CM) noise model is developed for an ac-dc-ac system with paralleled power modules. The CM noise contributions from both rectifiers and motor drives are analyzed. The interaction between the ac/dc rectifiers and dc/ac motor drives is explored. The CM noise reduction techniques which include a decoupling inductor technique and a CM noise balance technique are propos...
