Abstract
This paper proposes a methodology to study the reliability and failure analysis of new technologies of power transistors. The use of wide gap materials such as Silicon Carbide (SiC) and Gallium Nitride (GaN) is now a good alternative to meet the integration requirements of energy conversion systems. However, the reliability of these components is a crucial issue. Aging in operating conditions is considered, associated with electrical measurements to highlight nondestructive degradations of the performance of studied transistors. A step of looking for failure mechanisms in the material is made in order to identify any physical degradation. The information collected provide the user with valuable data and help to make an optimum choice of the component which can be integrated into the equipment. The presented work proposes the description of a methodology that meets these requirements and shows the study of two technologies of power transistors used in new generations of power converters.
