Nouvelles fonctions interrupteurs intégrées pour la conversion d'énergie

Abstract : Electrical power conversion systems are used in a wide range of common applications like public transport, general electronic, medicine or power distribution. A failure in common application is more often allotted to a failure in electronic devices. In addition, if we consider a power needs that grows dramatically, and an evolution in the way of mobility, we could say that modern power conversion system should have to be smaller, more reliable, and more powerful. Integration in power electronics is a good answer to these problems because its mains goals are to build smaller, more reliable and more powerful power conversion functions. This thesis deals with my contribution on the improvement of the reliability and the performance of a widely used power component: the IGBT. Firstly, an association of two different IGBT is presented. The goal of this association is to build a "low losses" architecture. Its concept and interest are exposed, and then its monolithic integration and technological realization are detailed. In a second part, a structure devoted to protect IGBT against short-circuit conditions is described. Its operation is explained and its design for monolithic integration is optimized and detailed.
