Available in PDF, EPUB and Kindle. Book excerpt: In power electronics designs, the evaluation and prediction of potential fault conditions on semiconductors is essential for achieving safe operation and reliability, being short circuit (SC) one of the most probable and destructive failures. Recent improvements on Wide-Bandgap (WBG) semiconductors such as Silicon Carbide (SiC) and Gallium nitrite (GaN) enable power electronic designs with outstanding performance, reshaping the power electronics landscape. In comparison to Silicon (Si), SiC and GaN power semiconductors physically present smaller chip areas, higher maximum internal electric fields, and higher current densities. Such characteristics yield a much faster rise of the devices’ internal temperatures, worsening their SC performance. In this way, this dissertation consists of a comprehensive investigation about SC on SiC MOSFETs, GaN HEMT, and GaN E-HEMT transistors, as well as contextualizing their particularities on SC performance by comparison with that of Si IBGTs. Moreover, an investigation towards how to prevent SC occurrences besides a review of available SC protection methods is presented.

Book excerpt: Wide bandgap (WBG) semiconductor materials allow higher power and voltage, faster and more reliable power electronic devices. These characteristics lead to a massive improvement in power converters, especially for electric vehicles (EV) applications. As a result, new opportunities for high efficiency and power density is coming with the development of WBG power semiconductor. This paper introduces the application of WBG devices in power converters of EV. The EV development trend and the related circuit diagram of an EV system have been introduced. Serval typical power converters' topologies have been discussed. Meanwhile, WBG devices also bring challenges to a high voltage and frequency design. High current and voltage levels need a more powerful heating system. A higher switching speed requires lower loop parasitic inductance. This paper discusses how to apply WBG devices in the power converter design and address these challenges. Finally, The reliability test method of power converters has been discussed. The lifetime of all components in a power converter has been tested under different voltage and temperature levels. The failure reasons and influences parameters are analyzed.
