Infinitus includes five components for power conversion, distribution, protection and cooling across DC and hybrid architectures.
ABB announced Infinitus, a portfolio of direct current (DC) power solutions for data centers with increasing power requirements from AI computing. The portfolio is designed to support DC and hybrid AC/DC architectures with the aim of improving energy efficiency, reducing power infrastructure footprint and increasing the power available for computing equipment.
The International Energy Agency (IEA) expects global data center electricity demand to more than double by 2030. ABB estimates that DC distribution could be used in approximately 25% to 40% of new data center capacity installed in 2030.
AI chips are expected to require 1 MW or more per rack, compared with nearly 200 kW today. ABB says 800 VDC distribution can reduce equipment footprint by eliminating some conversion stages and reducing heat losses associated with conventional alternating current (AC) systems.
A BCG and ABB report found that DC distribution can provide energy efficiency improvements of more than 5% and increase the space available for computing racks. In a 500 MW data center, a 5% efficiency improvement could provide 25 MW of additional power for IT loads. ABB estimates this could represent more than US$300 million in potential additional annual revenue, depending on operating and revenue assumptions.
Infinitus is an integrated DC portfolio that covers power delivery from the source to the rack. Its components include ABB’s Infinitus solid-state transformer technology, which is intended to support a smaller electrical infrastructure footprint and lower conversion losses. The portfolio also incorporates ABB’s IEC-certified solid-state circuit breaker and static medium-voltage uninterruptible power supply (UPS).
Infinitus portfolio components
- Medium-voltage powertrains: Deliver power from the grid or on-site generation to the facility.
- DC sources and power quality: Convert AC power to DC and move conversion equipment outside the data hall.
- DC power distribution: Deliver DC power to equipment while supporting higher power density within a smaller area.
- DC power protection: Protect operators, AI servers and other equipment from DC overcurrent conditions.
- Cooling optimization: Use DC-connected variable-speed drives and motors to manage cooling energy consumption in facility and data hall systems.
ABB works with customers to configure solutions based on power requirements, facility layout and available energy sources. The portfolio can be integrated with traditional AC systems and used in different power architecture configurations.
ABB expects several main Infinitus components to be produced over the next 12 months. The company expects the first DC-native facilities using the complete portfolio to be installed and operational within two to three years.
The portfolio also supports ABB’s collaboration with NVIDIA, announced in October 2025, on 800 VDC power architectures for gigawatt-scale AI facilities. ABB says it has more than 25 years of experience with DC systems and holds more than 700 patents related to renewable energy, power generation, energy storage, motors and drives.
