| Summary: | As the core component of electrification process, the power semiconductor device keeps improving, and constantly promotes the development of electrification devices and applications. The key technologies of power semiconductor devices mainly include four aspects: new material, new structure, new package and intelligence. The requirements for power semiconductor devices are different in different application scenarios. By analyzing the characteristics of typical application scenarios of rail transit, electric vehicle and electric power system, this paper analyzed and described the applications of fine trench insulated gate bipolar transistor, silicon carbide and intelligent integrated power devices with high power density. At present, power semiconductor devices are still in a rapid and steady development stage. Existing technologies are maturing and new technologies are emerging, there is a huge space for the development of key technologies in the four aspects. |
