August 27, 2026 Heat poses a real threat to the longevity and reliability of any electrical circuit. When subjected to excessive thermal stress, PCB materials and power components can drift outside the operating conditions they were designed for. Consequently, thermal management becomes a critical consideration when designing PCBs that incorporate high-power devices. For this reason,…
August 27, 2026 Introduction For decades, power electronics have relied predominantly on silicon, a semiconductor material that lends itself to essentially defect-free processing. Silicon’s theoretical performance ceiling, however, has now largely been reached, exposing several shortcomings: constrained voltage-blocking capacity, limited thermal dissipation, capped efficiency, and non-trivial conduction losses. Wide bandgap (WBG) semiconductors — chiefly silicon…
August 27, 2026 By: Maurizio Di Paolo Emilio, Contributing Editor at Panel Builder US Artificial intelligence is pushing data-center power architectures into territory they were never designed to handle. As AI accelerators become more powerful, rack power is moving from tens of kilowatts toward hundreds of kilowatts and, ultimately, the 1 MW range. At that…
August 13, 2026 Data centers are evolving faster than ever — driven by rising energy demands, the push for sustainability, and the integration of AI and edge computing. To better understand how these shifts are shaping data center infrastructure, operations, and connectivity, Data Centre Digest editor Garth Miller interviewed Pete Tecos, Director of Data Centers…
August 13, 2026 By: Maurizio Di Paolo Emilio, Contributing Editor at Data Centre Digest Artificial intelligence workloads are rapidly reshaping data center power architectures. Conventional server infrastructure was not originally designed to sustain today’s extreme compute density requirements. As a result, modern facilities increasingly resemble “AI factories,” where maximizing computational throughput per rack is a…
August 13, 2026 By Dr. Harsh Karandikar and Yasir Shinaishin, ABB The power density and scale of AI computing deployments are changing every aspect of how data centers are designed and operated. For decades, data centers had total IT loads measured in MWs and were built to support IT environments operating at less than 30…
August 13, 2026 By Sasha Ishmael, Principal Engineer, Technology and Industry Solutions, VEIR The data center industry is attempting to scale AI infrastructure with power delivery architectures designed for a fundamentally different era of compute density. AI workloads are accelerating demand for larger campuses, higher rack densities, faster deployment timelines, and increasingly complex electrical and…
August 13, 2026 By Jason Agee, Director of Data Center Solutions and Architecture, Delta Electronics In AI data centers running at 2+ megawatts per rack, the hardest aspect to get right is operations. That’s because extreme densities don’t just impose refinements on existing operating models; they break them. The failure modes at this density just…
August 13, 2026 By: Paul Quigley, Chief Strategic Relations Officer, AIRSYS Energy efficiency is not a new concept in the data center industry, but it is most often discussed in the context of hyperscale facilities. The rapid growth of AI has been closely associated with high-density hyperscalers, their rising power consumption, cooling demands, and global…
August 13, 2026 When Theory Meets Reality In 2025, Gartner predicted that by the end of the year, one-third of AI projects would not progress beyond the proof-of-concept phase. As we navigate 2026, that prediction has largely proved accurate. The gap between prototype success and production deployment is not primarily a technical capability—it is infrastructure…
August 10, 2026 Sponsored Article from ABB As power providers face increasing data center demand, digital substation technologies streamline grid interconnection while enhancing reliability, visibility, and lifecycle cost efficiency. By: Harsh Karandikar, Ph.D., VP of Product Management at ABB and Luiz Marques, Strategic Marketing Manager, Utility & Renewable at ABB After decades of relatively flat…
August 10, 2026 If you spend any time around data center projects in 2026, you hear the same phrase over and over: “We could build it if only we could get the power.” Demand for AI is strong. Land is often available. Network routes can be engineered. But in many markets, the grid is the…
August 10, 2026 Power as Foundation Power infrastructure is the foundation on which all data center operations rest. No matter how sophisticated the compute hardware, how advanced the cooling systems, or how intelligent the orchestration, without reliable power delivery, data centers cease functioning. In 2026, this fundamental truth faces unprecedented challenges as AI workloads drive…
August 10, 2026 By: Raghu Belur, Co-Founder and Chief Product Officer, Enphase Energy For most of the industry’s history, a data center’s limit was compute. Today, the limit is power. We’ve started describing capacity in megawatts and gigawatts instead of in racks or FLOPS, and that tells you where the constraint now sits. The electrical…
August 10, 2026 By: Maurizio Di Paolo Emilio, Contributing Editor at Data Centre Digest The fast growth of computational density of AI accelerators is fundamentally changing the design of power delivery networks (PDNs). Although rack power levels have increased from tens of kilowatts to several hundred kilowatts, processor core voltage levels have been kept below 1 V,…
