Optimisation du routage d'un filtre CEM

Abstract : The actual trend to integrate the power electronic devices naturally increases the stray electromagnetic phenomena. Every electrical system becomes thus an EM disturbances source. But as part of this work, we especially focused on the filtering device of conducted disturbances : the EMC filter. For high frequencies, degradations can be observed over the filter transfer function due to the different stray electromagnetic phenomena occurring within the device. But only the magnetic aspects have nevertheless been treated (i.e. partial inductances & stray magnetic couplings). Different methods have been worked out in the past in order to easily improve the filter response. However, these are empirical processes that could not guaranty the built filter solution optimality. The works done throughout this PhD have consisted in developing a novel EMC filter optimization method, and more precisely of its routing. The aim has been to use the different stray magnetic phenomena. All of these elements can only be obtained by using a PEEC modeling tool. The PEEC method allows having fast numerical calculations thanks to a quite light meshing.
