EMI Effects of Power Converters

Andrzej M. Trzynadlowski    University of Nevada, Reno, NV, United States

Abstract

This chapter is devoted to the effects of electromagnetic interference (EMI) generated by power electronic converters. The switch-mode operation of those converters is explained as a cause of the interference. Measurements of conducted EMI are described, and basic EMI parameters are defined. Common EMI filters and their mathematical models are introduced. Random pulse-width modulation as a means of EMI mitigation is presented. Other means of electromagnetic noise suppression, such as grounding and shielding, are reviewed. Various standards of the electromagnetic compatibility (EMC) are listed along the international institutions ...
