This course addresses the role of wide bandgap semiconductors for power electronics will be introduced. Furthermore, basic principles of these semiconductors but also IGBTs and MOSFETs will be discussed. Drivers and challenges regarding power electronics and integration as well as a more global perspective on this technology will address the potential of this technology. Additionally, the latest results of an IEA initiative (International Energy Agency), the IEA 4E PECTA (TCP: Energy-Efficient End-Use Equipment – Power Electronic Conversion Technology Annex) will be presented.
