Hyosung Chairman Targets U.S. AI Power with 22.9kV SST

Hyosung Chairman Cho Hyun‑Jun is zeroing in on the expanding U.S. AI power market with the launch of the world’s first 22.9 kV Solid State Transformer (SST). This breakthrough device replaces bulky, inefficient conventional transformers with a compact, high‑efficiency solution and scalable architecture tailored for AI data centers that demand stable, low‑latency power.

The new SST leverages next‑generation silicon‑carbide components to deliver superior power quality, faster response times, and reduced energy loss. By integrating thermal management and control, Hyosung ensures the transformer can handle the unpredictable loads generated by AI workloads while maintaining grid reliability while also reducing carbon footprint.

With local production facilities for both transformers and circuit breakers operational in the United States, Hyosung positions itself to meet domestic demand quickly and support the Biden administration’s push for resilient, clean energy infrastructure. Cho’s strategic focus underscores the company’s ambition to become a key player in the AI‑driven power ecosystem.
