Smart Grids and EV Charging Push Solid-State Transformer Demand

Electric vehicle charging is creating new requirements across urban power networks. Fact.MR reports that EV chargers are pushing solid-state transformers into high-demand applications, while grid stability programs increasingly depend on smart electronics that can respond to changing loads in real time.

Renewable energy is adding another layer of demand. Solar farms and other renewable installations create more variable power flows, increasing the need for transformers capable of flexible power management. Fact.MR states that the rapid expansion of renewable energy integration, smart grids, and electrified transport is accelerating adoption of solid-state transformers for efficient, bidirectional power conversion.

Shambhu Nath Jha, Principal Consultant at Fact.MR, said:

“An increasing number of Solid-State Transformers are becoming a vital component of next generation energy networks by supporting the expansion of smart electric power grids and enabling the integration of renewable sources of energy.”

Jha added that demand for advanced and efficient two-way AC-to-DC power conversion systems will support broader SST adoption across applications worldwide.

Distribution Transformers Lead the Product Segment

Distribution Solid-State Transformers are projected to hold a 47.6% market share in 2026, making them the leading product type. Fact.MR attributes this position to adoption in smart grids, medium-voltage distribution networks, and utility modernization programs.

Power Solid-State Transformers account for 35.2% of the product segment. Their use is supported by renewable energy integration and grid-scale power conversion.

Fact.MR defines the Solid-State Transformer market as advanced power electronic-based transformer systems that enable efficient voltage conversion, bidirectional power flow, and intelligent energy management across modern power grids and renewable energy systems.

Power Converters Hold 36.2% Share

Power Converters are expected to account for 36.2% of the market in 2026, making them the leading component category. Fact.MR links their position to their role in efficient AC/DC and DC/DC conversion within SST architectures.

Semiconductor Switches represent 30.8% of the market. Their adoption is supported by wider deployment of silicon carbide and gallium nitride-based high-efficiency power electronics.

The High Voltage/Medium Voltage (HV/MV) segment is projected to hold 50.6% share in 2026. Fact.MR connects this leadership to utility-scale transmission, smart grid modernization, and renewable energy integration.

The 100 kVA–1 MVA power-rating category holds 41.8% share, supported by deployment across distribution grids, EV charging infrastructure, and industrial applications.

Power distribution and smart grid applications account for 38.7% of the market. Ongoing grid modernization and demand for digitally controlled power networks support this position.

India Records the Fastest Growth

India is forecast to register the fastest growth among the countries covered, with the Solid-State Transformer Market projected to expand at a 16.6% CAGR through 2036. The United Kingdom follows at 16.5%, while China is expected to grow at 16.3%.

Fact.MR attributes India's growth to renewable energy expansion and modernization of transmission and distribution networks. The United States is projected to grow at 15.1%, Germany at 15.4%, Japan at 14.8%, and South Korea at 15.8% during the forecast period.

Across regions, North America and Europe benefit from established power infrastructure and advanced grid technologies. Asia-Pacific is seeing increased demand as smart grids, renewable energy integration, and transport electrification expand.

Companies Compete Around Power Electronics and Grid Infrastructure

The global Solid-State Transformer Market includes Hitachi Energy, Siemens, Eaton, DG Matrix, and GE Vernova among its leading companies. Fact.MR estimates that these companies collectively control approximately 40%–45% of total revenues from SSTs and next-generation power-electronics-driven infrastructure worldwide.

Other companies identified by Fact.MR include Delta, Grid Bridge, and Heron Power. Competition is centered on power electronics, smart grid technologies, electrification infrastructure, and advanced transformer systems.

Recent developments show the technology moving into new applications. In April 2026, Enphase Energy announced development of its IQ Solid-State Transformer for AI data centers. In February 2026, Exowatt selected DG Matrix's Interport Solid-State Transformer as a preferred power conversion platform for modular power systems serving hyperscale data centers.

In March 2026, Navitas Semiconductor and EPFL demonstrated a 250 kW solid-state transformer solution for AI data centers using silicon carbide devices. In October 2025, WattEV introduced a solid-state transformer designed for megawatt heavy-duty electric truck charging.

The market still faces adoption barriers. Fact.MR identifies high initial costs, limited experience with power-electronics-based grid infrastructure, and compatibility challenges with legacy transformer systems as key constraints.

Fact.MR's research combines primary interviews with manufacturers, semiconductor suppliers, smart grid solution providers, utilities, and distribution partners with desk research and market-sizing analysis. The forecast covers 2026 to 2036 across major global regions and more than 30 countries.
