Abstract :
This thesis work was dedicated to the implementation of a collaborative simulation method (or co-simulation) allowing the evaluation of electromagnetic compatibility phenomena of complex electrical systems through the “independent” simulation of all the subsystems that compose the global system without having to exchange and put together the models in the same calculation node (or simulation tool).
To achieve our objectives, a partitioning method based on Norton’s equivalent source and an iterative co-simulation algorithm have been proposed and tested on different applications modeled by electrical circuits (linear and non-linear). The first results on examples of linear electronic circuits demonstrated the potential of the developed method in terms of intellectual property protection and the gain in computation time compared to a classical simulation without splitting. Then, a study of the proposed method for the evaluation of conducted electromagnetic disturbances (common mode and differential mode) of power electronic converters was performed and validated by experimental measurements.
Finally, this method has been extended to the study of the coupling between the sub-parts of a complex multiphysics system (induction power transfer system for electric vehicles) which is modeled by electrical circuits on the one hand and by a 3D finite element model on the other hand. The proposed co-simulation algorithm allowed to consider each model in its original solver with its appropriate configurations and to achieve simulation results in agreement with those of a classical simulation or experimental measurements.
