Discussion sur le suivi de l’état de santé des modules de puissance constitués de MOSFET en carbure de silicium

Abstract : This paper deals with an overview of silicon carbide MOSFET-based power module failure modes and an experimental health-monitoring approach to detect them. A strong interest on power module reliability has emerged in industrial fields because of an increasingly frequent use of converters in power transmission systems. This study is anchored in a European project, called I²MPECT, in charge of a more integrated, intelligent and compact converter realization for aerospace use. The question of converter components reliability is so essential and require investigations. The converter designed by project members will be composed of silicon Carbide (SiC) MOSFET-based power modules, known for their performances, ten times higher than silicon technology. However, these power modules present some challenges in reliability field. In this paper, reliability issues will be described and a relevant monitoring method will be explained. Technological issues concerning health-monitoring test bench establishment will be also discussed.
