Abstract

The target of the BMBF-funded project “SiCnifikant“ is to develop and investigate the advantages of SiC-based semiconductor power modules within inverter configurations, suitable for electrical drive trains up to 250 kW at DC-link voltages up to 800 V. A broad range of investigations and simulations is performed. Starting from component level via module- and inverter-prototyping, up to the analysis of the system behaviour, especially with respect to the impact of steep switching slopes of up to 50 kV/μs, the project represents a holistic approach towards novel electrical drive trains.
