The power device in the charging module is upgraded from SiIGBT to the third-generation power semiconductor SiC MOSFET
As the core component of the DC charging station, the charging module accounts for about 50% of the total cost of the charging station, and the power device is an important component of the charging module.
At present, one of the technical problems faced by 800V DC charging stations is that with the increase of voltage and charging level, the charging module needs to have higher high-voltage costa rica number data resistance and power density. 800V high-voltage charging increases the DC power range of the charging module from 400V-750V to 800V-1000V, while the widely used SiIGBT power device has an upper limit of withstand voltage of 750V,
which needs to be upgraded to a SiCMOSFET chip with an upper limit of withstand voltage of more than 1200V. In addition to the outstanding high-voltage resistance performance, compared with traditional silicon-based devices, SiC modules can increase the output power of the charging station by nearly 30% and reduce losses by about 50%.
