Conception par optimisation de convertisseurs statiques pour applications mono-convertisseur multi-machines séquentielles ; contribution à l'optimisation du placement-routage.

摘要

Electric systems are more and more present in embedded applications. They replace mechanic or hydraulic systems. Regarding the replacement of a hydraulic system by an electric one, the mass profit is not significant but can be more considerable by mutualizing the inverters. The aim of that thesis’ work, which fit in as part of CISACS projects, is to develop a pre-sizing methodology of the power floor by considering multi-physics torsions and including the technical choices of components. The first chapter, through the context and the objectives of CISACS project, introduces the problematic of the conception of the static converters to load within future more electrified airplanes. In the second chapter, a functional and dysfunctional analysis of some sort of adjusted architecture to an application such as CISACS is done. Three architectures are considered: the first one, a classic structure with N converters, the second one a mono-points converters and the last one a structure of a matrix converters. In the third chapter, a progressive pre-sizing methodology of static converters by optimization under multi-physical constraints is proposed. Thanks to this methodology, the choice of the active and passive components is automated. In order to refine the sizing of the structure of retained power, we suggest in the last chapter a methodology of placement-layout of the semiconductors of power on sink plan. The implementation of the modelling calls on the electric-thermic-geometric aspects of the system.
