Core Viewpoint - The report from China Merchants Securities highlights the transition from traditional UPS systems to HVDC solutions in data centers due to increasing ICT equipment power density, which reveals the limitations of traditional UPS in efficiency, heat dissipation, and space utilization [1] Group 1: ICT Power Density Upgrade - The upgrade in ICT power density is driving the shift from traditional UPS to HVDC systems for primary power supply in data centers [1] - Data center power supply is structured in multiple levels, with primary power typically provided by UPS or HVDC systems, while secondary and tertiary power supplies cater to IT loads and chip-level requirements [1] - Traditional AC UPS systems are becoming inadequate in terms of load capacity, space efficiency, and economic viability, leading to HVDC becoming the mainstream technology for large and super-large data centers [1] Group 2: Development of 800V HVDC Solutions - Companies like NVIDIA are accelerating the development of 800V HVDC ecosystems by collaborating with power solution providers and upstream power device suppliers [2] - The overseas HVDC systems are more advanced than domestic solutions, incorporating components like BBU, supercapacitors, PDU, and Power Shelf, which enhance system performance and reliability [2] - Domestic HVDC solutions primarily rely on traditional architectures with lower voltage levels and lack the integration capabilities seen in overseas systems, particularly for AI load adaptation [2] Group 3: Opportunities for Chinese Companies - The large-scale adoption of HVDC may reshape the competitive landscape for traditional external power supply manufacturers, creating opportunities for Chinese companies to engage in OEM or collaborative product development [3] - Chinese firms possess advantages in power electronics technology, rapid response capabilities, and skilled engineering teams, positioning them well to enter overseas markets and achieve significant returns [3]

Summary of AIDC Power Technology Conference Call Industry Overview - The conference call focuses on the AIDC (Artificial Intelligence Data Center) power technology sector, particularly the transition from traditional UPS systems to 800V HVDC and SST technologies aimed at improving power supply efficiency and reducing maintenance and expansion difficulties [1][2]. Key Points and Arguments - **Technology Transition**: The industry is witnessing a significant shift towards high-voltage direct current (HVDC) systems, with major Chinese internet companies like BAT (Baidu, Alibaba, Tencent) adopting HVDC technology extensively, with Tencent's data centers reporting over 90% HVDC usage as of 2023 [1][5]. - **Market Dynamics**: The North American market has faced challenges in adopting HVDC due to initial setbacks, but the increasing power demands from GPUs and the competitive edge of renewable energy sources are driving a clearer trend towards HVDC adoption [1][5]. - **SST Advantages**: Solid-state transformers (SST) are highlighted for their ability to save space, reduce line losses, and improve overall efficiency compared to traditional transformer and HVDC combinations. SSTs are composed of electronic modules and high-frequency transformers, making them more competitive for companies with mid-to-low voltage electronic capabilities [1][7][8]. - **Concentration of Market**: The HVDC market is more concentrated than the dispersed UPS market, with a CR3 market share exceeding 90%, and companies like Zhongheng Electric holding about 50% market share. This concentration is expected to continue with the introduction of 800V HVDC and SST technologies [3][9]. Important but Overlooked Content - **Opportunities for Chinese Companies**: Chinese firms are positioned favorably in the overseas AIDC power market due to their cost advantages and the relatively low price sensitivity of power technology compared to chip segments. Companies with clear technological advantages and strong distribution channels, such as Zhongheng Electric, Jinpan Technology, and others, are recommended for investment [3][10]. - **Future Trends**: The call emphasizes the importance of channel advantages and R&D capabilities in selecting companies for investment, particularly in the SST sector, which is expected to see significant growth in the coming years [4][10]. - **Impact of Power Demand**: The increasing demand for power in data centers, particularly noted during peak usage periods in July and August, is pushing the need for more efficient power solutions, further enhancing the relevance of HVDC and SST technologies [5]. This summary encapsulates the critical insights from the conference call regarding the AIDC power technology landscape, highlighting the ongoing technological shifts, market dynamics, and investment opportunities within the sector.
