EMC Models for Power Electronics : from Converter Design to System Level

This paper presents different ways of modeling the EMC behavior of power electronics converters, which are more and more frequently connected to networks. After a brief presentation of some possible models, this work proposes a formal link between a comprehensive model, based on equivalent sources and including all details of the converter and a "Black Box" approach, far more compact and suitable for network studies. Thanks to this analytical link, the influence of the technological properties of the converter on the "Black Box" model can be studied, and some feedback on the converter design proposed.
