ABB has introduced Infinitus, a direct current (DC) portfolio developed to meet the increasing energy requirements of AI data centres.
The new portfolio will accelerate the shift towards DC architectures in data centres, aiming to improve energy efficiency, reduce the physical footprint of power infrastructure, and increase available computing capacity.

The Infinitus suite is described as an integrated source-to-rack DC system, incorporating solid-state transformer technology developed by ABB.
This technology is expected to enable more compact site designs while increasing energy efficiency.
The company states that the portfolio includes five main components: medium voltage powertrains, DC sources and power quality equipment, DC power distribution, DC power protection, and cooling optimisation.
ABB claims these elements can deliver stable power, convert AC to DC, support higher power densities, provide overcurrent protection, and lower energy use in cooling systems.
Global electricity usage by data centres is expected to more than double by 2030, according to the International Energy Agency. ABB estimates that between 25% and 40% of new capacity installed in 2030 could adopt DC distribution.
The latest AI chips may draw up to 1 MW per rack, up from current figures of almost 200 kW, which the company says necessitates a move to DC architecture to meet performance and efficiency requirements.
ABB reports that DC distribution at 800 VDC helps eliminate additional conversion steps, reduces heat losses associated with AC systems, and supports a more compact physical footprint.
ABB Electrification business area president Giampiero Frisio said: “ABB has pioneered DC technology for more than 25 years across several segments. We are working closely with chipmakers, hyperscale customers, supply partners and industry bodies to set the standards and the pace for the roll-out of high-efficiency DC architectures.
“Infinitus is the first portfolio providing the building blocks for any data centre architecture – either DC native or hybrid AC/ DC – to power next-generation AI chips efficiently. This technology will bring similar energy efficiency gains to other energy-intensive industries such as large scale manufacturing, renewables and marine operations.”
The company expects that main components of the Infinitus portfolio will be in production within the next year, with data centres using the full system anticipated to become operational in two to three years.
ABB’s ongoing collaboration with Nvidia, announced in October 2025, focuses on developing 800 VDC power architectures for large-scale AI infrastructure.
