Shanghai advanced trial production 6500V locomotive IGBT chip passed the identification of CRRC products

The “China CRRC Fully Independent Intellectual Property 6500V High Power IGBT Chip and Module Product Appraisal and Conference” organized by the China Electronics Industry Association Power Electronics Branch was held in Xi'an on October 22nd.

The “China CRRC Fully Independent Intellectual Property 6500V High Power IGBT Chip and Module Product Appraisal and Conference” organized by the China Electronics Industry Association Power Electronics Branch was held in Xi'an on October 22nd. The expert group commented that: by Shanghai North Car Yongdian Electronic Technology Co., Ltd. and Shanghai Advanced Semiconductor Manufacturing Co., Ltd. jointly developed the first IGBT chip for 6500V high-speed rail locomotives with complete intellectual property rights in China. The high-speed rail system was used to test the products, and the technology reached the world advanced level. A major breakthrough in the design and manufacturing process of high-voltage, high-current 6500V IGBT chips for domestic locomotives, especially the 6500V IGBT shutdown safety working area, short-circuit working area and other key technical bottlenecks.

The appraisal meeting was presided over by Xiao Xiangfeng, Secretary General of the Power Electronics Branch of China Electrical Apparatus Association, Lu Jianqiu, Chairman of the Power Electronics Branch of China Electrical Appliances Association, Gao Yong, President of Xi'an Engineering University, Professor Zhang Bo of the University of Electronic Science and Technology, Wen Xuhui, Research Fellow, Institute of Electrical Engineering, Chinese Academy of Sciences, National Power Electronics Standards Committee Secretary-General Wei Hongqi, deputy chief engineer of the Institute of Metallurgical Automation, and Li Liang, senior engineer of the Nanjing East Aircraft Division Technical Section, participated in the appraisal as experts.

As an important collaborating unit of Shanghai Advanced Semiconductor, Chairman Chen Jianming was invited to give a speech at the press conference, pointing out that the successful launch of 6500V locomotive IGBT products with full intellectual property rights will provide strong support for rail transit equipment represented by China's high-speed rail and electric trains. "China Core". According to the characteristics of the company, Shanghai Advanced focuses on the technology development and process upgrade of the special process of the integrated circuit industry. The 6500V IGBT chip designed and manufactured by Shanghai Advanced Semiconductor and Shanghai CNP Yongdian has passed the appraisal, marking the launch of large-scale commercial application. It also proves that it is effective and feasible to form strategic cooperation through the integration of domestic related companies to form the IGBT industrial chain for locomotives. .

Shanghai Advanced Semiconductor and China CRRC (formerly CNR) began joint research and development of IGBT chips for high-voltage and high-current locomotives in 2010. On October 22, 2014, Shanghai Advanced and the former China CNR officially signed the “Building Strategic Industry Alliance” in Shanghai. The cooperation agreement, through the cooperation of the strategic alliances of both parties, on the basis of making full use of their respective competitive advantages, jointly create a large-scale commercial industrial ecological chain with domestically-developed IGBTs with core competitiveness, forming IGBT chip design, chip process R&D and manufacturing, module packaging, The system applies a complete industrial chain.

Recently, Shanghai Advanced has achieved important results in the development and demonstration of IGBT technology in series of field terminations (including hydrogen injection forming field termination) at different voltage levels such as 6500V/3300V/1200V/650V. At present, Shanghai has accumulated more than 800,000 IGBT wafers and integrated into the national strategic industrial chain such as “high-speed rail, new energy vehicles, and smart grid”, and Shanghai Advanced Advanced Automotive IGBTs have also officially entered BYD. IGBT supply chain for energy vehicles.
