As a national strategic emerging industry, IGBT is widely used in rail transit, intelligent Electroweb, electric vehicles and new energy equipment and other fields, especially considered to be the core technology of new energy vehicles. However, at present, the domestic market in the high-end IGBT production capacity is insufficient, long-term dependence on imports.
At present, only three domestic manufacturers have the R & D and manufacturing capacity of automotive power semiconductor modules, and nearly 80% of the market share of domestic power semiconductor modules for electric vehicles is monopolized by European, American and Japanese enterprises such as Infineon, Valeo, Mitsubishi Electric, and so on. Sun Fengchun, academician of the Chinese Academy of Engineering, pointed out a few days ago that without autonomous controllable car chips, China's intelligent network-connected new energy vehicles will repeat the mistakes of joint ventures.
According to a report from Wuhan Workers' Day bao, in order to avoid the risk of importing power semiconductor modules from abroad, not only the price is high, but also the supply is unstable, and the supply may be "cut off" at any time, Dongfeng and CRRC jointly formed Zhixin Semiconductor in 2019. The new company built a power semiconductor module packaging and testing production line in Dongfeng New Energy Automobile Industry Park, and independently developed, manufactured and sold power semiconductor modules. In order to achieve import substitution.
The report also said that the overall performance of Zhixin Semiconductor's power semiconductor module is similar to that of similar foreign products, but the price is half cheaper than imported products. At present, the production line has completed installation and commissioning, small batch trial production is under way, module test and verification are carried out at the same time, and mass production is expected in April.
