This seminar will provide an overview of power semiconductors in typical automotive xEV applications such as traction inverter, on-board charger and DC/DC with the focus on the main inverter. The intention is to give a general picture starting from the highest level (OEMs & the Car Market) and going down stepwise to the Semiconductor itself touching Driveline Architectures as well as Semiconductor Power Packages. OEM & Car Market, Driveline Architectures & Power Applications, Semiconductor Power Packages, Semiconductors (Silicon: IGBT + diodes, RC-IGBTs & Wide Band Gap devices: SiC MOSFETs, GaN transistors) After presenting the typical characteristics of the different semiconductor solutions, design measures for optimizing Silicon as well as SiC will discussed: Optimization measures for Si and SiC devices - leading to some guidance which devices could be used in which application, Selection Criteria -Having a device selected does not mean that it can be easily bought (chip crisis). Therefore, the presentation will also address the chip market and the wafer supply and a method how to maximize the number of chips coming from a SiC raw wafer will be presented, Market & Supply - The tutorial will give engineers and managers a good insight into several topics: Which semiconductor is suitable for a certain application and why?, what are the trade-offs and the selection criteria for a specific semiconductor type?, And How could the market evolve over the next few years?
