The GaN high-electron mobility transistor (HEMT) structure has been widely investigated, particularly for radio-frequency applications. This structure is suitable for high-frequency switching applications in power electronics because of the high breakdown field of GaN and the high mobility of the channel. In this paper, a physical model for predicting the power-switching operation of GaN-based HEMTs...
The recent developments in SiC PiN diode research mean that physics-based models that allow accurate, rapid prediction of switching and conduction performance and resulting converter losses will soon be required. This is especially the case given the potential for very high voltage converters to be used for enabling distributed and renewable power generation. In this work an electro-thermal compact...
