Delta Electronics (2308), a major power supply manufacturer, will host the 2026 Taiwan International Smart Energy Week today and release its prefabricated solid-state transformer (SST) DC power solution to target the power supply needs of AI factories and data centers. It will also simultaneously display solid-state oxide fuel cells (SOFC). It is expected to trial mass production by the end of this year and expand its presence in the AI ​​energy infrastructure market.

Zhao Huachun, general manager of Delta's energy infrastructure business group, said that the rapid expansion of AI computing power is redefining the needs of enterprises for energy infrastructure. Microgrids can coordinate the power grid, independent power generation, energy storage and loads to instantly match energy supply with electricity demand. For the new generation power supply architecture, Delta has launched prefabricated SST DC power solutions and SOFC to help sites improve energy resilience and achieve energy independence.

Delta pointed out that the prefabricated SST DC power solution launched this time is specially designed for AI factories and data centers. It integrates SST with an energy conversion efficiency of 98.5%, DC-to-DC converter and control system, reducing the power conversion link in the power supply structure, improving overall energy usage efficiency, and supporting the flexible expansion of AI infrastructure.

In response to the rapid changes in AI computing loads, Delta said that this solution can be equipped with high-rate backup batteries according to site requirements, providing millisecond-level power support to maintain load-side power supply efficiency and stability. In addition, through factory pre-integration and modular design, on-site wiring, construction and system calibration work can be reduced, on-site deployment time can be shortened by 50%, and customers can accelerate the introduction of AI infrastructure.

In terms of its independent power generation layout, Delta Electronics simultaneously exhibited SOFC, which generates electricity through electrochemical reactions and combines it with heat recovery technology to achieve an overall power generation and heat energy utilization efficiency of up to 85%. It is expected to be put into trial mass production by the end of this year. SOFC can be integrated with existing power grids, energy storage systems and other energy equipment to reduce the site's dependence on a single power source and enhance the power supply resilience of AI data centers, manufacturing plants and critical infrastructure that operate 24 hours a day.

Delta Electric further pointed out that it has recently joined hands with Greater Taipei Gas to build the first Taiwan-made 550kW SOFC project site to promote local independent power generation applications. The theme of this exhibition is "Resilient Energy, Driving the Future of AI". Microgrids integrate power grids, independent power generation, energy storage and smart dispatch to help companies cope with the power demands brought about by AI computing and smart manufacturing.
