The solid-state transformers market for US data centers was valued at USD 40.3 million in 2025 and is projected to reach USD 154.0 million by 2030, growing at a CAGR of 30.8% during the forecast period.

“Based on semiconductor device type, the silicon carbide (SiC)-based segment is expected to witness the highest CAGR during the forecast period.”

The silicon carbide (SiC)-based SST segment is expected to witness the highest CAGR in the solid-state transformers market for US data centers due to the increasing demand for high-efficiency power conversion systems. SiC-based devices support higher switching frequencies, lower energy losses, and improved thermal performance in high-density computing environments. These characteristics make SiC-based SSTs suitable for AI-driven hyperscale data centers requiring compact and energy-efficient electrical infrastructure. SiC technology also enables higher power density and supports fast voltage regulation across medium-voltage power distribution architectures. Increasing deployment of liquid-cooled AI clusters and high-capacity GPU servers is further accelerating the adoption of SiC-based solid-state transformers. In addition, growing investments in advanced power electronics and intelligent energy management systems are supporting segment growth across modern US data center facilities.

“Based on deployment type, the new installation segment is expected to account for the largest market share during the forecast period.”

The new installation segment is expected to account for the largest share of the solid-state transformers market for US data centers due to the rapid construction of hyperscale and AI-driven facilities. Large data center operators are investing in next-generation electrical infrastructure to support increasing computing power demand. New installations allow operators to integrate medium-voltage SST architectures, intelligent power management systems, and modular electrical infrastructure from the initial design stage. These deployments also support higher energy efficiency, lower power losses, and improved space utilization across high-density environments. The growing development of liquid-cooled AI data centers and renewable-powered facilities is further accelerating demand for new SST deployments. In addition, increasing investment in scalable, grid-connected power infrastructure is supporting the adoption of solid-state transformers across newly constructed US data center campuses.
