Silicon carbide (SiC) is a compound semiconductor material composed of carbon and silicon, and has the characteristics of wide band gap with gallium nitride (GaN), so it is called the third generation semiconductor material.
Because SiC has a wide band gap, it has high breakdown electric field strength and other material characteristics. Benefiting from the material characteristics of SiC, SiC power devices have the advantages of high voltage resistance, small size, low power consumption, high temperature resistance, etc.
Silicon Carbide Application in Electric Automotive
Electric drive inverter is the main application field of SiC in automobile. On new energy vehicles, the main application fields of SiC are electric drive inverter, on-board charger (OBC) and DC/DC converter.It is predicted that by 2026, inverter applications will account for more than 80% of the automotive SiC device market, and will be the most important application field.
SiC devices used in electric drive inverter can significantly reduce the volume, weight and cost of power electronic system, and improve power density; Applied to vehicle charger and DC/DC system, it can reduce switch loss, improve limit operating temperature and improve system efficiency. In addition, SiC can also be applied to the charging pile of new energy vehicles to reduce the volume of the charging pile and improve the charging speed.
Electric vehicles can improve efficiency and battery life by using SiC inverter. The advantage of using SiC devices in the electric drive inverter is on the one hand to reduce the loss and improve the efficiency, and on the other hand to reduce the cost of the whole system. Specifically, reduce the volume and weight of the inverter. Because the chip area of the SiC device itself will be reduced, and its working frequency is high, it can save the peripheral passive components, so the SiC module volume will be smaller than the IGBT module; SiC has good heat dissipation and reduces the volume of the cooling system.
More and more vehicle models are equipped with SiC power devices. With Tesla adopting full SiC power devices in the main inverter of Model 3 for the first time, more and more manufacturers begin to release models equipped with SiC devices, including BYD, NIO, Xpeng, Mercedes, etc. With SiC devices, these newly released vehicles can achieve smaller inverters and on-board chargers, higher inverter efficiency, and higher power density, thus improving the driving power, charging speed, and endurance of the vehicle.
