On December 12, according to the official news of Dongfeng Automobile, as a "CPU" in the power electronics industry, IGBT (insulated gate bipolar transistor) is internationally recognized as the most representative product in the electronic revolution. Multiple IGBT chips are integrated and packaged together to form an IGBT module, which has greater power and stronger heat dissipation ability, which plays an extremely important role and influence in the field of new energy vehicles.

In order to break through the blockade and realize the independent control of IGBT core resources, in 2019, Dongfeng Company joined hands with CRRC to establish Zhixin Semiconductor Co., Ltd. and began to independently develop and produce vehicle-grade IGBT modules. After two years, in July 2021, the annual IGBT production line with an annual output of 300,000 was officially put into operation in Wuhan Dongfeng New Energy Vehicle Industrial Park, which is also the first fully automated sealing pipeline of IGBT modules in China.

Charge 80% in 10 minutes, and Dongfeng silicon carbide module will be mass-produced next year.

As an upgraded product of the IGBT module and a third-generation semiconductor, the silicon carbide power module has the characteristics of lower loss, higher efficiency, higher temperature resistance and high voltage. According to reports, the silicon carbide power module project was established in Zhixin in January 2021. At present, the project has been successfully completed and will be equipped with Dongfeng independent new energy passenger vehicles in 2023 to achieve mass production. This module can promote the iteration of the electrical architecture of new energy vehicles from 400V to 800V, which can achieve a 10-minute charge of 80%, and further improve the vehicle range and reduce the cost of the whole vehicle.

IT Home learned that the second phase of the power module project with a total investment of 280 million yuan of Dongfeng Automobile is also accelerating. It is reported that on the one hand, the project optimizes the existing production line and improves the output of IGBT modules, and on the other hand, it opens up two new production lines to produce IGBT modules and silicon carbide power modules according to order requirements. By 2025, about 1.2 million power modules can be provided for the production of Dongfeng new energy vehicles every year.
