| Abstract |
In this paper, a 15 kW drive inverter design with increased switching frequency demand for the high-speed drive of an automotive electrical turbo-compressor unit is described. After comprehensive simulation-based evaluations eight inverter prototypes using different wide-band-gap power semiconductor devices are built and operated. With the aggregated measurement results the simulation models are refined and the inverter design is optimised in terms of efficiency, power density and its thermal characteristics. Finally, a fully functional drive inverter prototype is built. |
