Abstract:
An electric drive system includes an induction machine and a power converter electrically coupled to the induction machine to drive the induction machine. The power converter comprising a plurality of silicon carbide (SiC) switching devices. The electric drive system further includes a controller that is electrically coupled to the power converter and that is programmed to transmit switching signals to the plurality of SiC switching devices at a given switching frequency such that a peak-to-peak current ripple is less than approximately five percent.
