FREQUENTLY ASKED QUESTIONS
The Infinitus DC portfolio is an integrated source-to-rack direct current power portfolio for AI data centers. It brings together the building blocks needed for DC-native and hybrid AC/DC architectures, including medium-voltage powertrain solutions, 800 VDC power conversion, power quality, distribution and protection solutions, and cooling optimization technologies.
The Infinitus DC can deliver efficiency gains of more than 5%, helping reduce end-to-end energy and heat losses, conductor and copper requirements, and power infrastructure footprint. This enables reliable, high-density power delivery while making more power and space available for computing.
The Infinitus DC portfolio is the industry's first integrated source-to-rack DC portfolio. At its core is ABB’s breakthrough Infinitus solid-state transformer (SST) technology, enabling sites to operate with a smaller footprint and greater energy efficiency. As the only major electrification supplier with both the world's first fully IEC-certified solid-state circuit breaker and an industry-first static medium-voltage UPS in production, ABB delivers a breadth of technology unmatched in the market.
800 VDC enables higher power transfer at lower current, helping to reduce conductor requirements, distribution losses and infrastructure footprint. NVIDIA introduced the architecture for future megawatt-class AI systems. In October 2025, ABB announced a collaboration with NVIDIA to support the development of 800 VDC power architectures for next-generation AI data centers. The wider industry is increasingly aligning around 800 VDC through initiatives such as the Open Compute Project (OCP). While higher voltage levels may emerge as power requirements evolve, 800 VDC provides a practical common foundation for the next generation of AI data centers.
The Infinitus solid-state transformer (SST) converts medium-voltage AC power directly to 800 VDC using high-frequency solid-state power conversion, helping reduce conversion stages, energy losses, and infrastructure footprint.
As AI data centers become more compute-intensive, efficient cooling is essential to performance and uptime. ABB's high-efficiency motors and drives optimize pumps and cooling equipment, helping improve energy productivity while maintaining optimal thermal conditions. ABB's drive technology is also ready for emerging DC architectures, helping operators maximize the computing capacity they can deliver from every megawatt of available power.
ABB provides electrification and automation solutions to help customers design, build and operate data centers that are more reliable, efficient and scalable. ABB has been a trusted partner in global electrification for over 140 years. Around the world, one in four data centers run on ABB technology. ABB brings over 25 years of applied DC technology deployment and over 700 DC patents. ABB works with hyperscalers and chipmakers, including NVIDIA, and collaborates with industry bodies, including the Open Compute Project (OCP), Open Data Center Alliance and Current/OS to shape standards.
ABB co-leads the Open Compute Project’s (OCP) Data Center Facility Power Distribution subproject and leads its Protection and Safety workstream. ABB also participates in the Open Data Center Alliance and Current/OS, contributing to the specifications, safety requirements and interoperability needed for wider DC adoption.
ABB is helping advance a future in which AC and DC architectures work together, with DC increasingly supporting high-density AI infrastructure where it creates the greatest value. Through Infinitus DC and industry collaboration, ABB is developing the technologies and standards needed for this transition.
ABB expects that DC will play a growing role in energy-intensive applications where it offers clear technical and economic advantages. While data centers present the most immediate need, other energy-intensive industries, including manufacturing, renewable energy, marine operations, EV charging, and energy storage, could benefit from more efficient power conversion and distribution.
