High-speed rail will use "Chinese core"

China National North Car Group Co., Ltd. recently released in Xi'an: High-power IGBT chips (insulated gate bipolar transistors) were identified by experts and put into mass production. Since then, China has completely independent proprietary high-power IGBT "Chinese core."

According to reports, as a new generation of semiconductor devices, IGBT is a key core component of automatic control and power conversion, and is widely used in the rail transit equipment industry, power systems, industrial frequency conversion, wind power, solar energy, electric vehicles and household appliances industries.

Previously, domestic high-end IGBT chips basically relied on imports. The successful development of this high-power IGBT chip will not only provide a strong "Chinese core" for China's high-speed rail, EMU and other rail transit equipment and other related industries, but will also gradually improve the status of all domestic high-power IGBTs that rely on imports and reduce them. The cost of rail transit development in China. At present, China has become the world's largest consumer of IGBT chips, with annual demand exceeding 7.5 billion yuan, and growing at a rate of more than 30% per year. By 2020, China's rail transit electric traction industry will not have an annual IGBT chip market size. Below 1 billion yuan, the smart grid is no less than 400 million yuan. According to reports, together with CNR, there are currently only four companies in the world that have mastered this technology.
