Topological approach for assessment of electromagnetic interferences to support mechatronic conceptual design

Abstract

The conceptual design is a crucial phase for the System Architects to evaluate 3D architecture concepts of mechatronic systems mainly with regard to the ElectroMagnetic Compatibility (EMC). Our research work deals with the combination of electromagnetic modeling and a topological approach to support the qualitative and quantitative ElectroMagnetic Interferences (EMI) evaluation process within the MBSE SAMOS approach as of the conceptual design. For a given interference, the analysis of topological models allows the qualitative identification of the existence of victims with their associated potential aggressors, based on the electrical schema of interacting components. Then, once the potential EMIs have been qualitatively identified, a quantitative evaluation can be performed based on the predefined electromagnetic and geometrical requirements, and on the analysis of the identified physical coupling law. Finally, this approach has been applied to the alien crosstalk occurring in an electrical vehicle powertrain, with a quantitative evaluation based on the two following methods: an analytical approach and Kron's approach.
