Abstract
SiC semiconductors promise to be a good alternative to Silicon (Si) semiconductors, as they offer large savings in volume, weight and losses of the inverter. Also, the switching frequency can be extended by a factor of 10 compared to current insulated gate bipolar transistors (IGBTs), which allows the use of motor filters with small component size. This paper first presents the dimensioning of a 10 kW air-cooled SiC inverter, which has been designed for the purpose of output filter characterization. The main part includes the design and characterization of an output dv/dt filter for highly-integrated Silicon Carbide (SiC) inverter systems used in traction drive or in more electric aircraft applications. Several tests at full output power of 10 kW and 600V DC-link voltage as well as efficiency measurements verify the system design.
