Low-inductance, high-efficiency induction machine

摘要

An electric drive system includes an induction machine (60) and a power converter (58) electrically coupled to the induction machine (60) to drive the induction machine (60). The power converter (58) comprising a plurality of silicon carbide (SiC) switching devices (72-82). The electric drive system further includes a controller (114) that is electrically coupled to the power converter (58) and that is programmed to transmit switching signals to the plurality of SiC switching devices (72-82) at a given switching frequency such that a peak-to-peak current ripple is less than approximately five percent.
