en.Wedoany.com Reported - Xi'an XD Power Electronics Co., Ltd. (referred to as "XD Power Electronics"), a subsidiary of China XD Electric Co., Ltd. (601179.SH), has recently secured a batch order for solid-state transformers (SSTs) dedicated to an overseas data center, signing contracts for 4 units of 13.8kV AC/800V DC specification products. These devices will be used to build an efficient, safe, low-carbon, and intelligent new power supply system for the overseas data center. This order marks the official entry of domestically produced solid-state transformer technology into the international mainstream market.
Xi'an XD Power Electronics Co., Ltd. was established in 2022 with a registered capital of 50 million RMB, headquartered in Xi'an, Shaanxi Province. The company is a core subsidiary of China XD Electric Group Co., Ltd., which is under China Electric Equipment Group, and serves as the group's power electronics business platform in the source-grid-load-storage sector. Its core business covers multi-scenario power electronics converters (PCS), AC/DC hybrid distribution network solutions, advanced energy storage grid integration solutions, power quality monitoring and management solutions, as well as R&D on third-generation semiconductor power device packaging and testing technologies. XD Power Electronics focuses on cascaded PCS products, with voltage levels covering 35kV and 10kV, rated power ranging from 2.5MW to 50MW, and a supply track record exceeding one hundred megawatts. In 2025, its parent company, China XD Electric Group, saw overseas revenue grow by 54% year-on-year, with R&D expenses reaching 1.199 billion RMB, an increase of 48.39% year-on-year.
A solid-state transformer is a new type of power equipment that uses semiconductor power devices to achieve voltage transformation and power quality management through high-frequency isolation. Global next-generation intelligent computing centers are accelerating the transition to 800V high-voltage DC power supply systems. As a core component, the solid-state transformer can complete the conversion from medium-voltage AC to low-voltage DC in a single step. Compared to traditional line-frequency transformer solutions, it improves overall operational efficiency by 3 to 5 percentage points and reduces equipment volume by over 60%. According to industry research institutions, the global power solid-state transformer market size reached 9.9 billion RMB in 2025 and is expected to grow to 23.49 billion RMB by 2032. Prior to this overseas order, XD Power Electronics' self-developed 10kV/2.42MVA solid-state transformer had been applied in China's Gui'an National "East Data West Computing" data center project, and the 10kV/2MVA/750V solid-state transformer had been grid-connected and put into operation in the XD Smart Park's solar-storage-charging smart energy system in Xi'an High-tech Zone. China XD Electric previously stated in December 2025 that its solid-state transformer products had not yet received overseas market orders; this signing achieves a "zero breakthrough" in the overseas market.
XD Power Electronics stated that it will continue to deeply cultivate the R&D and manufacturing of solid-state transformer products, further promote power electronics technology to empower computing infrastructure, and provide guarantees for digital infrastructure construction with reliable products and high-quality performance.
