molecular pump in semiconductor of application

Silicon carbide (SiC) is very rare in the natural environment. It was first discovered in meteorites in the solar system 4.6 billion years ago, so it is also called “semiconductor material that has experienced 4.6 billion years of time travel.” Compared with traditional silicon devices, SiC devices have advantages in switching speed, breakdown field strength, band gap, electron saturation speed, melting point, and thermal conductivity.

Silicon carbide

Silicon carbide is a compound semiconductor material composed of carbon and silicon. And gallium nitride (GaN), aluminum nitride (ALN), gallium oxide (Ga2O3), etc., are collectively referred to as wide-bandgap semiconductor materials due to their band gaps greater than 2.2eV, and are also called third-generation semiconductor materials in China.

SiC semiconductor materials have excellent properties, especially as components for power conversion and control. Compared with traditional silicon devices, they can work stably under low on-resistance, high-speed switching, and high temperature and high pressure resistance, so they are popular in power supplies, automobiles, railways, industrial equipment, and household consumer electronics.

With the development of electric and hybrid vehicles, SiC is also rapidly emerging in this field, involving industries including energy (PV, EV charging, smart grid), automobiles (OBC, inverters), infrastructure (servers), etc. In addition, power storage and charging stations are also target markets. Silicon carbide power devices provide a wide range of on-board application solutions for electric vehicles and hybrid vehicles, and are mainly used in on-board chargers, step-down converters and main drive inverters.

Another application of SiC is photovoltaic power generation, mainly solar inverters, which are only half the size of IGBT-based solutions. The faster switching speed of SiC means that manufacturers can reduce the size of passive components in the system, large capacitors and transformers can be miniaturized, and the size of the heat sink can also be reduced. As system efficiency increases, energy capture can be maximized .
