Abstract |
The presence of numerous power electronics converters on embedded networks, originates EMCissues. EMC modeling of power electronic converters is tricky due to modeling complexity. Indeed,on one side, EMC study needs the finest characterization of each element, thus, only a few numbers ofconverters plugged to the network can be described. On the other hand, a conventional networkapproach, representing the converters on a pure functional point of view, does not allow such analysisof each element.Therefore “black box” or “grey box” approaches, representing the global behavior of the converters,are a good compromise between those two antagonistic needs.This article aims to sum-up characteristics of different EMC models in order to justify the choice ofterminated approach. Then, all identification issues will be addressed:• Theoretical difficulties such as the physical meaning of the identified impedances.• Practical difficulties like attenuated conditions sizing and measurement protocol. |
