Electric Motors

Description

For electric vehicles, power electronics are critical for several functions, but perhaps most relevant of all is the traction inverter, which converts the DC power from a high-voltage (HV) battery into AC power to supply the traction drives of an electric vehicle. Today, different drive concepts like front-wheel drive, rear-wheel drive, or even wheel hub motors are used. The focus of development is always on increasing performance and efficiency, which leads to new control approaches, drive concepts, power electronics devices (e.g., silicon carbide SiC), and motor types.  The drive unit is used by different vehicle functions and has to be integrated into the vehicle network. This also makes the integration process and the development of interfaces more complex.
