The Power Electronics Reliability (PowER) Laboratory at the department of Electrical, Electronic and Information Engineering of the University of Bologna is a modern facility where tests on semiconductor power devices and related circuits are performed to assess robustness and endurance of advanced technologies based on silicon (Si), gallium nitride (GaN) and silicon carbide (SiC), in collaboration with semiconductor companies and international research laboratories such as STMicroelectronics and IMEC.
In particular, the analysis of power devices and circuits are performed through:
- Development of experimental techniques for the characterization of short- and long-term degradation phenomena occurring in semiconductor power devices;
- experimental characterization of wear out effects and of the underlying microscopic mechanisms in advanced power devices provided by technological partners;
- semi-empirical modelling of the devices degradation by means of accelerated stress tests and TCAD physics-based simulation;
- Design and prototyping of power circuits, such as DC-DC converters, specifically oriented to the in-situ analysis of the wear out affecting semiconductor power devices operating in realistic conditions.
