AI算力扩张驱动固态变压器需求增长

Group 1: Market Demand and Growth - The demand for Solid State Transformers (SST) is increasing due to the rapid expansion of AI computing power, with the global AI market expected to grow from 1,187.9 billion yuan in 2023 to 11,455.4 billion yuan by 2030, achieving a compound annual growth rate (CAGR) of over 35% [1] - The global SST market is projected to grow at a CAGR of 25% to 35% over the next 5 to 10 years, according to predictions from Anshan China Big Data Center [1] Group 2: Technological Advantages - SSTs are set to upgrade traditional transformers, which are typically oil-immersed or dry-type and operate at 50Hz, due to the increased power demand and requirements for stability and safety brought by AI computing [2] - Traditional transformers are large, heavy, and have an efficiency of around 95%, while SSTs utilize power electronic devices and high-frequency technology, significantly reducing size and weight, and improving efficiency [2] - SSTs can achieve power conversion efficiencies exceeding 98%, support high power and dynamic loads, and simplify the power supply chain [3] Group 3: Company Developments - Domestic companies are accelerating their entry into the SST market, with China West Electric Co., Ltd. having developed SST capabilities and already supplying a 2.4MW SST to a data center [4] - Hainan Jinpan Intelligent Technology Co., Ltd. has completed the design and production of a prototype SST suitable for HVDC800V power supply architecture [4] - TBEA Co., Ltd. has provided products and solutions for multiple key data center projects and plans to continue strengthening market development and R&D investment in this area [4] Group 4: Broader Applications - The demand for SSTs is expected to be driven not only by data centers but also by sectors such as renewable energy integration, electric vehicle fast charging stations, and smart grids [5]
