Shanghai made high-speed rail high-power IGBT chip passed the identification

On September 17th, it was learned from China CNR Group that the high-power IGBT chip (insulated gate bipolar transistor) designed and manufactured by Shanghai Yongji Motor Co., Ltd. passed the expert appraisal. After the chip is localized, it will generate billions of yuan in output value every year in the fields of high-speed rail construction, power systems, green energy, and electric vehicles.

It is reported that the official name of this chip is 3300V/50A-IGBT chip. As a new generation of semiconductor devices, it has the advantages of easy driving, simple control, high switching frequency, low on-voltage, large on-state current, low loss, etc. It is a key component of automatic control and power conversion, in rail transit, industrial frequency conversion. It is widely used in the wind power, solar energy and home appliance industries.

Previously, domestic high-end IGBT chips basically relied on imports, and were completely subject to foreign companies in terms of delivery cycle and purchase price. The successful development of this high-power IGBT chip will not only provide a strong "China core" for China's high-speed rail, EMU and other related rail transportation equipment and other related industries, but will also gradually improve the current domestic high-power IGBTs relying on imports and reduce the situation. China rail transit development costs.

At present, China has become the world's largest consumer of IGBT chips, with annual demand exceeding 7.5 billion yuan, and annual growth rate of more than 30%. Relevant surveys show that by 2020, China's rail transit electric traction industry will have an annual market size of IGBT chips of not less than 1 billion yuan and a smart grid of no less than 400 million yuan. Therefore, the successful development of high-power IGBT chips in Shanghai not only fills the gaps in related fields in China, but also creates huge economic benefits.

It is expected that by the end of this year, Shanghai Yongji Motor Co., Ltd. will form a complete IGBT device package design and manufacturing platform with a capacity of 300,000 welded and crimped IGBT modules and 4 million smart IGBT modules.
