Problem
Traditional medium‑voltage power infrastructure relies on bulky, low‑frequency transformers and discrete converters, which limits efficiency, hampers precise control, and reduces resilience as electricity demand grows from AI data centers, electrified industry, and distributed energy resources.
Solution
Polyax offers solid‑state transformer (SST) systems that replace conventional transformer‑converter stacks with a compact, high‑frequency architecture. By integrating high‑frequency transformers, modular power converters, advanced digital controls, and fast protection mechanisms into a deployable medium‑voltage platform, the solution delivers higher conversion efficiency, tighter voltage regulation, and rapid fault isolation. The modular design supports high‑density power delivery, seamless integration of energy storage, and flexible expansion of grid capacity. This enables utilities, data‑center operators, and industrial facilities to meet rising load demands while improving power quality and system resilience.
Target Audience
Primary customers are utility operators, hyperscale data‑center providers, and industrial enterprises undertaking large‑scale electrification projects such as EV charging infrastructure, hydrogen plants, and microgrid deployments.
