Compared with silicon (Si) devices, silicon carbide (SiC) power devices can effectively achieve high efficiency, miniaturization and light weight of power electronic systems. The energy loss of silicon carbide power devices is only 50% of that of Si devices, the heat generation is only 50% of that of silicon devices, and it has a higher current density. At the same power level, the volume of silicon carbide power modules is significantly smaller than that of silicon power modules. Taking the intelligent power module IPM as an example, using silicon carbide power devices, the module volume can be reduced to 1/3 to 2/3 of silicon power modules.

There are 3 types of silicon carbide power diodes: Schottky diodes (SBD), PIN diodes and junction barrier control Schottky diodes (JBS). Due to the Schottky barrier, SBD has a lower junction barrier height, so SBD has the advantage of low forward voltage. The emergence of silicon carbide SBD increased the application range of SBD from 250V to 1200V. At the same time, its high temperature characteristics are good, from room temperature to 175°C limited by the shell, the reverse leakage current hardly increases. In the application field of rectifiers above 3kV, silicon carbide PiN and silicon carbide JBS diodes have attracted attention due to their higher breakdown voltage, faster switching speed, smaller volume and lighter weight than silicon rectifiers.

Silicon carbide power MOSFET devices have ideal gate resistance, high-speed switching performance, low on-resistance and high stability. It is the preferred device in the field of power devices below 300V. It is reported that a silicon carbide MOSFET with a blocking voltage of 10kV has been successfully developed. Researchers believe that silicon carbide MOSFET will occupy an advantageous position in the field of 3kV to 5kV.

Silicon carbide insulated gate bipolar transistors (SiC BJT, SiC IGBT) and silicon carbide thyristors (SiC Thyristor), silicon carbide P-type IGBT devices with a blocking voltage of 12kV have good forward current capability. The on-resistance of silicon carbide IGBT devices can be compared with unipolar silicon carbide power devices. Compared with Si bipolar transistors, SiC bipolar transistors have 20-50 times lower switching losses and lower conduction voltage drop. Silicon carbide BJT is mainly divided into epitaxial emitter and ion implanted emitter BJT, and the typical current gain is between 10-50.
