Delta Debuts DC Power System for AI Data Centers

Oct 14, 2026
Delta Electronics introduced a prefabricated DC power system that combines solid state transformers, DC/DC converters and control equipment for AI data centers.

Delta Electronics unveiled a prefabricated solid state transformer based DC power system in a press release at Energy Taiwan 2026. The system combines solid state transformers, DC/DC converters and control equipment for AI data centers and high density computing facilities.

Delta says its solid state transformers reach efficiency of up to 98.5%. The company says the system can improve efficiency from the grid to chips by 4% to 5% and reduce on site deployment time by up to 50% through its modular design.

The system can include a high C rate battery that provides millisecond level support during rapid changes in AI computing loads. Delta also presented microgrid components including energy storage, intelligent power dispatch and solid oxide fuel cells, with trial production of its fuel cell solution planned by the end of 2026.

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.
