Conception multi-niveau multi-physique de systèmes mécatroniques automobiles : prise en compte de la contrainte de fiabilité de convertisseurs de puissance embarqués dans un véhicule hybride/électrique

Abstract : This PhD thesis work is in the context of electric/hybrid vehicle embedded subsystems electrification. In mechatronic design field, the permanent objectives are costs and delays reducing. To achieve this, there is need of design methodologies and appropriate tools to perform a reliable design approach and leave maximum of risks before making the first prototypes. Embedded mechatronic systems mobilize technological brick keys which include the power electronic converter. Their performances are based on the capacity of the design methodologies to consider the environment multi-disciplinary constraints, the adequacy of the technologies, topologies and control laws. This thesis work shows how we can meet these requirements and needs through the development of multi-physics and multi-level design methodology for multi-level converters (interleaved) predisposed to an easy reconfiguration. This methodology, based on optimization under multi-physics constraints allows systematic choice of optimal architecture and component technologies from manufacturer database. It integrates the reliability aspect in the design since the pre-sizing process in the same level as the other constraints (electric, efficiency, thermal, volume, electromagnetic compatibility). In order take advantages of such interleaved converters, the integration of reliability in the design "reliability by design" is completed by the development of fault tolerant control architecture "reliability by control" which increase the availability by reconfiguring hardware or software (control law) of the designed converter.
