ABB and BCG Report Backs Hybrid AC/DC Power for AI Data Centers

September 09, 2026
A report from ABB and Boston Consulting Group says AI computing, electrification and renewable energy are increasing demand for direct current power systems.

ABB and Boston Consulting Group published a report on hybrid alternating current and direct current power systems, ABB said in a press release. The report says AI computing, electrification and renewable energy are increasing the role of direct current technology, while alternating current will remain central to transmission and regional distribution networks.

Solar systems, batteries, electric vehicles, AI data centers and many industrial automation systems operate on direct current. The report says reducing power conversion steps can improve efficiency, increase usable grid capacity and simplify integration.

The report identifies 800 VDC distribution as an emerging architecture for AI infrastructure, where it can increase computing capacity within constrained grid connections. It lists fragmented standards and a shortage of skills specific to direct current systems as the main barriers to wider use.

Whitepaper

Tensordyne Napier: What If One Rack Could Do the Work of Nine?

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
