Power Electronics for Data Centers Market (2026-2036)

The growth of this market is mainly driven by the rising rack power density of AI systems and the shift to 800 VDC and higher-voltage power architectures. Efficiency mandates and energy cost pressure also drive demand for higher-efficiency power supplies, UPS systems, and cooling drives. However, cost and supply constraints for SiC and GaN devices and long qualification cycles at hyperscale buyers restrain the growth of this market.

Furthermore, solid-state transformers for grid-to-rack conversion, vertical and high-density power delivery to accelerators, and the replacement of aging UPS and power fleets are expected to offer growth opportunities for market stakeholders. However, thermal density and reliability in compact power shelves and safety standards and arc protection for high-voltage DC remain major challenges. Additionally, the adoption of wide-bandgap (SiC and GaN) devices, OCP Open Rack power standards and disaggregated power racks, and digital and AI-based power control are prominent trends in this market.

The Power Electronics for Data Centers Market covers sales of equipment that converts, conditions, and switches electrical power between the utility feed and the processor. It also covers the drives that run cooling motors. IT-side equipment includes server and storage PSUs, rack power shelves, and HVDC power racks and sidecars, while board-level equipment includes intermediate bus converters, voltage regulators, and point-of-load modules. Facility equipment covers modular and centralized UPS power conversion systems, rectifiers and DC power systems, solid-state transformers, and static transfer switches. Cooling motor drives cover variable frequency drives and EC fan drives for chillers, pumps, air handlers, fan walls, and coolant distribution units.

Each item is counted once, at the equipment level that the buyer purchases, and market value is measured at the vendor selling price. Semiconductor devices such as silicon, SiC, and GaN transistors are not counted separately, because their value sits inside the equipment. Switchgear, conventional transformers, cables and busway, basic PDUs, generators, and batteries are excluded, while the conversion electronics around batteries are included. According to onsemi (September 2026), AI data centers manage power from tens of thousands of volts at the grid to under 1 V at the processor core.

Demand comes from two groups of buyers, which shapes where the market is recorded. Server makers and original design manufacturers (ODMs) buy PSUs, power shelves, and board-level converters for every server and rack they assemble, mainly in Taiwan, China, Mexico, and the U.S. Data center operators and their contractors buy UPS systems, rectifiers, static transfer switches, and cooling drives where each facility is built. This purchase basis explains why Taiwan and Mexico rank among the largest country markets even though their own data center construction is modest. Taiwan supplied 36% of U.S. server imports in the first half of 2026 and Mexico 34.5%, according to Mexico News Daily (August 2026).

Rising AI rack power has moved a large part of the value of this market into the rack. NVIDIA plans 800 VDC production from 2027 for racks of up to 1 MW and more. This design moves AC-to-DC conversion into sidecar power racks and adds a new DC-DC stage in each compute rack. Value therefore shifts between product types rather than leaving the market. Competition is moderately concentrated. Taiwanese power supply makers such as Delta Electronics, Lite-On, and AcBel now meet facility power suppliers such as Vertiv, Schneider Electric, and Eaton in 800 VDC sidecars and SSTs.

“Our current AI halls run on 54 V shelves, but we cannot keep adding shelves as racks move past 200 kW. We are qualifying ±400 VDC and 800 VDC sidecars now, and we will not commit until we have two qualified sources and a protection scheme our safety team accepts.”

This reflects why the high-voltage DC architecture is the fastest-growing rack power architecture, and why long qualification cycles and DC safety standards remain key restraints and challenges.

“Every rack we build carries power shelves, PSUs, and voltage regulators, so our power purchases follow our rack output. More of that assembly is moving to Mexico and Texas, and our suppliers need to ship from plants close to those lines.”

This highlights why Asia-Pacific is the largest region today, why China and Taiwan grow below the market, and why Mexico and the U.S. gain share as rack assembly moves closer to U.S. buyers.

“Grid capacity in our core metros is the hardest constraint we face, so we raise output from existing halls first. When UPS systems reach mid-life, we replace them with higher-efficiency modular frames that free floor space and help us meet PUE targets.”

This indicates why the replacement of aging UPS fleets is a key opportunity and why modular UPS grows faster than centralized UPS.

“We are building gigawatt-scale capacity from almost nothing, so every phase needs UPS, transfer switching, and cooling drives sized for dense GPU racks. Halls that open from 2027 are being designed with 800 VDC and solid-state transformers in mind.”

This reflects the role of sovereign AI campuses in making the Middle East & Africa the fastest-growing region and Saudi Arabia the fastest-growing country.
