ABB has launched Infinitus, an integrated direct current (DC) power portfolio designed to support the electricity requirements of AI data centers. This announced technology aims to address the transition toward racks requiring significantly more power.
Why it matters
As AI chips scale toward 1 MW per rack, current power delivery methods face efficiency constraints that this architecture seeks to mitigate. The system aims to accommodate projected demand as global data center electricity consumption is expected to more than double by 2030.
The Infinitus portfolio uses 800 VDC distribution to achieve energy efficiency gains of more than 5%. For a 500 MW data center, this efficiency improvement potentially yields 25 MW of additional capacity for IT loads.
The players
ABB
A global electrification and automation technology company that holds over 700 patents related to power technology.
The details
The Infinitus portfolio employs solid-state transformer technology—electronic devices that manage voltage levels using semiconductors rather than traditional copper coils—to create an integrated source-to-rack DC architecture. By utilizing 800 VDC distribution, the system reduces the number of conversion steps and subsequent heat losses that typically occur in AC-to-DC power chains. This is designed to support the jump from current 200 kW rack requirements to next-generation AI chips that require 1 MW per rack.
Timeline
September 21, 2026: ABB launched the Infinitus DC power portfolio.
2028-2029: The first DC-native Infinitus facilities are expected to become operational.
2030: Global data center electricity consumption is projected to more than double.
The Tech Race
This release follows the industry-wide push to solve the power density constraints facing AI infrastructure. It positions ABB against existing AC-based power delivery standards by leveraging the company's 25 years of DC technology experience.
Data center operators and hyperscalers will see this technology reach the deployment phase within two to three years. The portfolio primarily benefits facilities managing high-density AI clusters that require significant efficiency gains to lower operational costs.
The takeaway
The race to optimize power density for AI is shifting focus toward integrated DC architectures to curb heat loss. Watch for pilot facility announcements in 2028 to verify the claimed 5% efficiency gains in large-scale deployments.
