Hyosung Heavy Industries reports development of a 22.9 kV solid-state transformer
Редакция ЦОД:Главное
Hyosung Heavy Industries has developed a 22.9 kV solid-state transformer (SST) that, according to S1, can connect directly to urban distribution networks. The equipment uses power semiconductors and digital controls, and may offer an alternative approach to power conversion and connection for energy-intensive loads.
- Hyosung Heavy Industries has reported development of a 22.9 kV SST for direct connection to urban distribution networks.
- The SST uses power semiconductors and digital controls; S1 also reports AC-to-DC conversion capability.
- Potential value for data centers lies in more flexible power conversion, control and grid connection rather than replacing new generation or network construction.
- No commercial deployments, customers, certification details, pricing or production information were provided for the Hyosung system.
- Grid-equipment lead times and transformer-price pressure could increase interest in alternatives that address interconnection bottlenecks.
Hyosung Heavy Industries has developed a 22.9 kV solid-state transformer, or SST, that S1 describes as capable of connecting directly to urban distribution networks. S1 characterises the product as the world’s first 22.9 kV SST with that capability, although the material provided does not include a primary technical source supporting the claim.
Unlike conventional transformer designs relying solely on traditional electromagnetic components, the SST uses power semiconductors and digital control. S1 also says the equipment can convert alternating current to direct current. For data-center power architectures, such functionality could potentially support more flexible power conversion and load-management configurations at the distribution-network interface.
The development is being presented against a backdrop of rising U.S. data-center electricity demand and supply-chain pressure in grid equipment. S1, citing Lawrence Berkeley National Laboratory, states that data centers consumed about 4.4% of U.S. electricity in 2023 and that the share could rise to 15% by 2030. Separately, S1 cites the International Energy Agency as projecting that data centers could account for roughly half of U.S. electricity-demand growth by the end of the decade.
Grid constraints are not limited to generation availability. S1 reports that procurement of core grid equipment can take more than two years, while prices for some transformers have increased by as much as ninefold over the past five years. In that environment, technologies that improve conversion, control or connection flexibility could become relevant to data-center interconnection strategies.
Commercial relevance remains unproven on the information available. No customers, pilot projects, production volumes, pricing, certification, or operating deployments for Hyosung’s SST were identified in the source material. If the technology is validated through commercial supply and scalable deployment, it could form part of the solution set for easing selected bottlenecks in connecting high-load data centers to distribution networks. It should not, however, be viewed as a substitute for additional generation or wider grid expansion.
For data-center operators, grid constraints increasingly extend beyond available generation to distribution capacity, interconnection flexibility and procurement lead times for critical equipment. If validated in commercial deployments, SSTs could broaden the options for connecting and managing large data-center loads, although they would not remove the need for new generation and grid build-out.
