Description

Wide Bandgap Semiconductors GaN, SiC module was created to introduce this emerging field in the engineering technology and related associate level curriculum.  In section 1, the history of the development of WBG power devices is presented. This is followed in section 2 by a discussion of their numerous advantages, their use as switching devices, and their challenges. In section 3, the device structure, operation, and testing procedure are reviewed. The subjects of device driving issues and typical circuitry using WBG devices are both considered in section 4. In section 5, applications and sample circuit block diagrams are introduced. A case study of a high-power inverter with application to photovoltaics or electric vehicles is described in the final section.
