China successfully developed a fuel cell multi-energy energy storage system using domestic smart modules

According to the website of the Ministry of Science and Technology, the theme of "Research and Development and Application of Key Technologies for Power Electronics Using Energy Storage Systems Made by Domestic Smart Modules" in the "86th Plan" Advanced Energy Technology Project of the "12th Five-Year Plan" Period in the Intelligent Insulated Gate Bipolar Transistor (IGBT) Energy-saving system has made important progress in the key technologies of power electronics, breaking through a series of key technologies of IGBT intelligent module design, control driving and protection, process and test, breaking the key power electronics technology of multi-energy energy storage system, International leader. The project is undertaken by Zhejiang University, jointly with Xiamen Kehua Hengsheng Co., Ltd., Jiaxing Star Semiconductor Co., Ltd. and other units to complete. Recently, this project passed the project acceptance organized by the High-tech Department of Ministry of Science and Technology.

The project successfully developed 1.2kV, 1.7kV IGBT intelligent power module series, developed with independent intellectual property rights intelligent IGBT module design method of intelligent power modules to overcome the high-performance semiconductor power chip layout technology and other problems. Based on the developed domestic intelligent power module, the power electronics system design method of multi-energy energy storage system has been developed for long standby, safe, reliable and efficient disaster prevention power supply, including power electronic power conversion architecture scheme, multi-energy coordinated control, fault tolerance Technology and so on. In Zhangzhou Industrial Park, Fujian Province, the world's first demonstration system of emergency power supply for major projects including fuel cells, natural gas, electricity and other energy sources was established.

It is reported that the power electronics smart module with its high power conversion efficiency, high reliability, good control performance and other outstanding advantages, as the power electronics devices and systems core components, widely used in new energy power generation, data centers and cloud computing, industrial automation and Energy saving, aerospace and defense and other fields. High-power energy storage system is to deal with sudden disasters to provide uninterruptible power supply is the key technology, is China's major projects reliable power supply key infrastructure, which has high reliability requirements, energy-saving environmental protection requirements of high, is restricting China's data center, precision Manufacturing, nuclear power and other important bottlenecks in the development.
