Propagation Phenomena of Conducted Disturbances in a Converter Powered through a LISN

Abstract

Nowadays, power electronics have an important role in power processing and control systems of various applications, but can face some electromagnetic compatibility issues. In order to understand those electromagnetic compatibility issues, the first step is to find the origin and the propagation paths of electromagnetic disturbances in a power electronics structure. In this paper is presented a full study of the source of disturbances and parasitic couplings, as well as the role of a LISN in the context of standardized measurements.
