Nvidia(US:NVDA) 中金点睛·2025-09-23 23:58Core Viewpoint - The construction of AI computing power centers (AIDC) is on the rise, and solid-state transformers (SST) are expected to become the preferred solution for future data center power supply architectures due to their high efficiency, compact size, flexibility, and prefabricated design [2][6]. Group 1: SST Technology and Market Potential - SST is anticipated to become the optimal technology route as AI power supply architecture upgrades to 800V HVDC, with major cloud providers increasing capital expenditure and accelerating AIDC construction [2][10]. - SST offers significant performance advantages over traditional UPS supply chains, including over 3 percentage points improvement in efficiency, 60% reduction in footprint, and 75% decrease in installation and debugging time [3][16]. - The initial investment cost of SST is currently high, but there is substantial potential for cost reduction as core components like power semiconductor devices and amorphous nano-crystalline materials mature [3][12]. Group 2: Industry Landscape and Competitive Positioning - Major global AIDC players like Eaton and Delta have early reserves in SST solutions, while domestic companies are entering the market from traditional power equipment, AI power supply, and solar storage sectors [3][27]. - Companies with deep understanding of power electronics, high-frequency transformers, and mid-voltage processing, along with rich experience in data center projects, are expected to stand out in the SST market [3][28]. Group 3: Policy and Green Energy Integration - The introduction of policies supporting green electricity direct connection presents new opportunities for SST promotion in data centers, emphasizing the importance of green computing [14][16]. - SST is well-suited for scenarios that require collaboration between computing power and electricity, aligning with the "AI+" development direction [14][16]. Group 4: Technical Advantages of SST - SST significantly enhances space utilization and power supply efficiency, making it a strong candidate for direct current power supply in data centers [16][22]. - The modular design of SST allows for prefabricated installation, reducing construction cycles to less than 90 days and simplifying maintenance [22][24]. - SST supports integration with renewable energy sources, enhancing green energy consumption and meeting the requirements for integrated source-grid-load-storage systems [22][24].
