Réseaux de micro convertisseurs, les premiers pas vers le cicuit de puissance programmable

Abstract : DC/DC power converters are widely used for domestic and industrial applications with powers from a few watts to several MegaWatts. Generally, for each application, an appropriate converter is designed to meet the specifications. So, with a new application corresponds a new converter leading to systematic review and re-design of a new structure of conversion which is costly in time and money. Eventually, it can lead to specific technological developments which also have an impact on the cost of developing solutions for power electronics. To circumvent these difficulties, my thesis focuses on the process of Micro Converters Networks (MiCoNet) which proposes a new approach to respond fully flexibely to any specifications. The aim of this approach is to create a unit component, called elementary cell, able to respond to any kind of specifications by connecting in series and/or parallel several of these elementary cells. It permits to adjust the voltage and/or current of the converter to achieve. Therefore, my thesis is divided into two main parts. The first part consists in the design and the integration of the elementary cell used in the MiCoNet. The second discusses the configuration strategies used in the MiCoNet and association modes of elementary cells which can respond to any specification.
