Develop an ultra-compact motor for electric vehicles, combined with an inverter on silicon carbide. Electric cars and hybrids are progressing very quickly, which brings to life more and more large batteries that store energy for electric motors. It came to the fact that in the Chevrolet Volt batteries partially occupied the salon, sitting between the passengers not only the first but also the second row of seats; for this they even had to sacrifice one footprint. By the way, isn’t the low popularity of the model connected with this, which led to its recent withdrawal from production? To avoid such restrictions in the future, manufacturers of hybrid cars and electric vehicles are struggling to reduce the size of the electric motor and auxiliary systems. Here is the option for the Application of silicon carbide in the field of electric vehicles .
In the new development of Mitsubishi, instead of a separately made electric motor and an inverter, the placement of both units in one cylindrical housing was used. The use of SiC-based chips in the element base of the inverter has become a key solution that has drastically reduced the size and weight of the new integrated system.
The fact is that in existing inverters on silicon, overheating of the element base leads to failure of the device itself. When using a much more heat-resistant silicon carbide, its normal functioning is possible at temperatures up to 600? C, which significantly exceeds the performance of analogs. Such a high-temperature inverter requires
