With the support of national and local science and technology projects such as the "Construction of a Public Platform for High Voltage IGBT Module Product Testing and Assessment" and the "Innovative Capacity Building of the Beijing Engineering Laboratory for High Power Electronic Device Packaging Technology in Electric Drive Systems" of the Beijing Municipal Development and Reform Commission, the Institute of Electrical Engineering of the Chinese Academy of Sciences has established the earliest testing platform for high voltage and high power electronic devices in China. The platform currently has more than 30 world-class semiconductor testing equipment, which can conduct electrical parameters, long-term reliability, and failure analysis testing and research on power semiconductor products. Since its official operation in 2013, the high-voltage and high-power power electronic device testing platform of the Institute of Electrical Engineering of the Chinese Academy of Sciences has provided services and support for national scientific and technological innovation, and is open to social users such as universities, research institutes, and enterprises, achieving resource sharing as the foundation. In terms of supporting national scientific and technological innovation, the testing platform is responsible for the research on the basic theory and evaluation methods of SiC devices and systems for high-temperature vehicles undertaken by our institute and external units, the development of high reliability power electronic integrated systems for commercial vehicles, and the key technologies and applications of customized ultra-high power IGBT for flexible DC transmission equipment crimping Multiple national key research and development projects such as "Research on Basic Theory of Silicon Carbide High Power Electronic Devices and Applications" have provided semiconductor device testing and appraisal services, effectively supporting the research and development work in the field of national semiconductor devices and breakthroughs in key technical issues. In addition to providing support for the development of national science and technology, the testing platform also provides services for multiple key industries related to the national economy and people's livelihood. For example, in 2018, entrusted by CRRC, it completed the screening of nearly 50 in-service Harmony high-speed trains, totaling over 7000 6500V/600A high-voltage IGBT modules, making outstanding contributions to ensuring the stable operation of high-speed rail. From 2019 to 2020, at the request of State Grid Corporation of China, the testing platform provided evaluation and identification of domestically produced 4500V/3000A crimped IGBT devices for the "Zhangbei Renewable Energy Flexible DC Grid Test Demonstration Project" and "Chongqing Hubei Flexible DC Back-to-Back Networking Project", providing a solid guarantee for the successful application of domestically produced devices in the national backbone power grid and achieving domestic substitution. In order to standardize the management of the testing platform and enhance the credibility of the testing results, in October 2014, the testing platform officially passed the evaluation of the China National Accreditation Commission for Conformity Assessment and became a national third-party testing institution (CNAS registration number: L7181, CMA registration number: 152 0173 38406). Since then, the testing platform has provided third-party testing services for the entire industry chain of power semiconductors in China, including chip design, device packaging, and applications. As of June 2021, there are over 100 enterprises, universities, and research institutes serviced by the testing platform, with an average annual testing of over 1000 components The above article is a partial list.
