Summary of Key Points from the Conference Call Industry Overview - The conference call primarily discusses the advancements in the AIDC power supply industry, particularly focusing on solid-state transformers (SST) and the implications of NVIDIA's new technologies [1][2]. Core Insights and Arguments - NVIDIA's Blackwell GPU is projected to achieve total sales of $500 billion, indicating strong market demand which positively impacts the AIDC power supply sector, especially the silicon transformer segment [1][2]. - The introduction of an 800-volt direct current (DC) power supply architecture aims to enhance power efficiency, reduce material usage, and optimize space utilization in data centers [1][4]. - The transition to the 800-volt DC power supply will occur in three phases: retrofitting old data centers, implementing new facilities without UPS systems, and ultimately adopting medium-voltage rectifiers or transformer configurations [4][9]. - Solid-state transformers (SST) offer significant advantages over traditional transformers, including reduced size, higher integration, and improved space utilization through advanced rectification and inversion technologies [5][8]. Important Developments - NVIDIA's recent GTC technology summit revealed that over 6 million Blackwell GPUs were sold in the past four quarters, showcasing robust demand for NVIDIA products [2]. - Jinpan Technology has clarified its research and sales plans for SSTs, boosting market confidence in the application and development of SSTs [2][11]. - The AIDC power supply architecture has undergone notable changes over the past year, with a clear trend towards technological iteration and efficiency improvements [3]. Additional Insights - When selecting A-share targets, companies with channel advantages should be prioritized over those with purely technical strengths. Companies like Jinpan Technology and Sungrow Power are highlighted for their overseas channels and integrated capabilities [10]. - Jinpan Technology has completed the iteration of its SST 2.0 version and plans to release the 3.0 version by 2026, marking its entry into the North American market [11]. - Sungrow Power benefits from a strong overseas market presence and has accumulated significant experience in traditional large storage businesses, positioning it well for growth in the SST market [12][13]. - Sifang Co. and Zhongheng Electric are noted for their potential in the SST field, with Sifang already possessing complete product capabilities and expanding overseas channels [14]. - In the high-frequency transformer segment, Jin Jianhua Company is recommended for its strong channel development and reliability [15].
