Toward a reliability analysis method of wide band gap power electronic components and modules

This study is addressing on the reliability of COTS (Commercial Off-The-Shelf) power electronic components and modules which could be used in high reliability systems such as aerospace systems. This paper details the first followed steps to achieve a reliability assessment of some COTS power devices. These first steps are: Construction analyses for the determination of the packaging assembly technologies of COTS power devices; Discussion on the material used in COTS power devices; Synthesis of the potential failure risk analysis under harsh environments; Determination of several accelerated ageing tests to check the potential failure modes and mechanisms in power electronic for aerospace systems.
