China's first high-power IGBT chip has passed appraisal


  Modern high-speed trains have motors in each carriage. To ensure that the power from each carriage works together seamlessly, a high-power chip is required. Previously, China relied heavily on imports for this type of high-end chip. The successful development in Shanghai of a high-power IGBT (Insulated Gate Bipolar Transistor) chip, following expert evaluation, marks a significant step. This first domestically designed and manufactured "China core" chip not only replaces imports but is also projected to generate billions of yuan in annual output value across various sectors, including rail transit, power systems, green energy, and electric vehicles.
 
IGBT is the "core of the core"
 
  This chip, officially named the 3300V/50A IGBT chip, was designed and manufactured by Shanghai CRRC Yongdian Electronics Technology Co., Ltd., a subsidiary of CRRC Corporation Limited. The lead researcher is Academician Zou Shichang of the Chinese Academy of Sciences and Chief Technical Advisor of CRRC Corporation Limited. This breakthrough has enabled CRRC to establish a complete industrial chain in the high-power, high-end IGBT field, encompassing chip design, manufacturing, and module packaging, placing them in a leading industry position.
 
  The biggest advantage of IGBT is energy efficiency. As a new generation of power semiconductor devices, it boasts easy driving, simple control, high switching frequency, low conduction voltage, large on-state current, and low loss, making it a crucial component in automatic control and power conversion. For example, in high-speed trains, the traction drive system is a core component, and the IGBT is the core component of the traction drive system – the "core of the core."
 
  The applications of IGBT extend far beyond high-speed trains and locomotives in the rail transit industry. It is also widely used in power systems, industrial frequency conversion, wind power, solar energy, electric vehicles, and home appliances.
 
China is the largest consumer of IGBTs
 
  This high-end chip has always relied on imports, making China completely dependent on foreign companies for delivery times and purchase prices. China is now the world's largest consumer of IGBTs, with an annual demand exceeding 7.5 billion yuan and growing at a rate exceeding 30% annually. Data predicts that by 2020, the market size for IGBT modules in rail transit electric traction alone will be no less than 1 billion yuan, and no less than 400 million yuan in smart grids. Therefore, the successful development of high-power IGBT chips in Shanghai not only fills a gap in domestic related fields but will also gradually replace imports, creating enormous economic benefits.
 
  Meanwhile, CRRC Corporation Limited revealed that it has mastered the design and development technology of high-voltage IGBTs and can customize chip characteristics based on the actual needs of various application fields. In crucial areas related to national livelihood, such as rail traction and smart grids, this will drive the research and development of new technologies and products. In the economic fields of wind power generation and electric vehicles that utilize new energy and new power sources, this will promote the development of green economies. In fields such as petrochemicals, mining, machine tools, and metallurgy, this will promote the emergence of more efficient and energy-saving inverters and high-frequency switching power supplies.

The Future of Electrical Equipment Manufacturing: Technological Innovation in High-Frequency Switching Power Supplies

The Future of Electrical Equipment Manufacturing: Technological Innovation in High-Frequency Switching Power Supplies In today's rapidly developing era, the electrical equipment manufacturing industry is facing unprecedented challenges and opportunities. In particular, technological innovation in high-frequency switching power supplies is bringing new vitality to this industry. So, what is a high-frequency switching power supply? And how does it drive the future of the electrical equipment manufacturing industry? Basic Concept of High-Frequency Switching Power Supply Simply put, a high-frequency switching power supply is a device that controls energy conversion through high-frequency switching technology. Imagine a faucet; different water pressures and flow rates determine the amount of water supplied. A high-frequency switching power supply is like this faucet, precisely controlling the output of electrical energy. They are widely used in communications, industrial control, medical equipment, and other fields. Technological Innovation in High-Frequency Switching Power Supplies In recent years, the technology of high-frequency switching power supplies has been constantly innovating. First, the improvement in efficiency is obvious. Imagine you are cooking in the kitchen; if the thermal efficiency of the gas stove is improved, you can not only save gas but also shorten the cooking time. This is equally important for high-frequency switching power supplies. By adopting more efficient conversion technologies, manufacturers can not only reduce energy consumption but also reduce the heat generated by the equipment, improving overall performance. Furthermore, the size reduction is also significant.
