| Abstract |
Concerns have been raised that motor voltages might be very high if the fast switching characteristics of silicon carbide (SiC) are to be utilized. For this reason, the magnitude of the terminal voltage of an induction motor is investigated when fed from a fast switching SiC inverter through a long cable. It is found that the main insulation demand for the SiC case is only increased by 5 \% compared to the silicon insulated-gate bipolar transistor (IGBT) case. This indicates that additional _lters may not be necessary in applications with long cables where silicon IGBTs are replaced by fast switching SiC power semiconductors. |
