Multiple manufacturers are actively launching new SST (Solid-State Transformer) products, indicating an acceleration in the industry's commercialization progress.
On June 3, Eaton released its MVSST Solid-State Transformer 2.0. It features 10kV medium-voltage direct input and 800VDC single-stage conversion, achieving a full-chain efficiency of 98.5% and a power density of up to 278kW/m². The delivery cycle is shortened by 50%, and it has been operating stably for over a year.
On June 6, Tgood released the world's first prefabricated power station for computing centers, the "Computing Power Island." Utilizing SST technology, it enables high-voltage direct input and 800V DC output, compressing substation construction time to just five months.
On May 28, Zhiguang Electric, in collaboration with China Huaneng Group's Clean Energy Technology Research Institute, jointly launched the Coota 1.0 solid-state transformer. It supports flexible expansion from 1-4.2MW, achieves single-stage conversion from 10kV AC to 800V DC, reduces footprint by 60% compared to traditional solutions, and is better suited for diverse scenarios like AIDC and supercharging systems.
On March 28, Xinfengguang disclosed its new-generation SST product. This fully self-developed product accepts 10kV input and delivers 800V DC output with a power rating of 2500kW. It boasts advantages such as high power density, low loss, and high functional integration. Voltage coverage extends to 13.8kV, making it perfectly adaptable to complex application scenarios in new power systems.
Additionally, Delta, Eaglerise, and Sifang have also released new products in 2026. The pace of SST solid-state transformer industrialization is accelerating, with positive prospects for the industry's initial deployment phase and subsequent volume scaling.
SST Adoption Accelerates with Positive Long and Short-Term Trends
With the explosive growth of global computing power, the electricity load of data centers is rising rapidly, intensifying the contradiction between power supply and demand. NVIDIA's whitepaper explicitly outlines the technological pathway, positioning SST as the ultimate solution for upgrading power distribution architectures in data centers for the AI era.
Simultaneously, as a new type of power system, SST is a key piece of equipment for achieving the integration of source, grid, load, and storage, indicating vast potential for demand growth.
Since 2026, leading domestic and international manufacturers have intensively released new SST products or announced related progress, demonstrating rapid advancements in technological maturity and commercialization.
In the short term, SST is expected to achieve large-scale adoption first in the data center sector. In the long term, the application space for SST solid-state transformers in charging桩 and grid-side applications is also extensive.
The significant trend towards SST solid-state transformer industrialization is viewed favorably, and domestic companies with relevant SST layouts are expected to benefit substantially.
Key Risks to Consider
Potential risks include SST solid-state transformer industrialization falling short of expectations and capital expenditures from overseas CSP (Cloud Service Provider) manufacturers not meeting forecasts.
