Power Semiconductors – the Keys for a Future Green Mobility
Patrick Leteinturier, Clemens Mueller
Abstract
The mobility industry is living the most disruptive period since the invention of the internal combustion engine. The society is looking for carbon-neutral as well as carbon-zero transportation. This keynote will address the fundamental changes in the Electric Electronic (EE) architecture and the vehicle architecture to address the CO2 challenges with electro-mobility. It will review the main building blocks: batteries, inverters, and converters among others. The digital transformation and the IoT are strongly modifying the way we design power electronics (MOSFET, IGBT, SiC and GaN). More than the cars and the complete automotive value chain, the announced changes will affect the energy infrastructure. The first step will be the electricity-charging infrastructure with charging at home, at destination, and on the way. The next step could go into new energy carriers such as hydrogen or other synthetic fuels. Finally, the electrification of cars in combination with bidirectional charging will help to balance the energy flows within smart grids.
