Figure 1: Evolution of data center power architecture: (a) today: AC distribution, integrated IT racks; (b,c) next-gen systems: AC distribution, disaggregated IT racks with 50 V servers (b) or 800 V servers (c); (d) future systems: data center-wide HVDC, 800 V servers
The rapid growth of AI and accelerated computing is fundamentally reshaping power‑delivery requirements inside modern data centers. As GPU clusters scale towards and beyond 1 MW/rack, traditional 48 V rack‑level distribution is reaching its practical limits due to high currents, thermal stress, and increasing cop

Welcome to the May issue!
April’s issue dealt with the immediate aftermath of APEC, and this month I’d like to get into some specifics.
Amongst a plethora of new developments, two specific themes stood out – the decline of EVs and the ascension of artificial intelligence.
Most companies and OEMs stil

Welcome to the May edition of Power Systems Design Europe. Even before the AI boom, the roll out of data centres were happening extremely quickly. Data centres enable some of the most essential services we use today, for example hosting web sites, and running IoT applications. That importance will only grow in

Figure 1: An example using the Saf-D-Grid Max connector demonstrates that, at constant ambient temperature, connector temperature increases as applied current increases
AI acceleration and high-performance computing (HPC) architectures are fueling an unprecedented rise in data center demand. Goldman Sachs expects global data center power demand to surge +160% by 2030, and AI server racks in 2027 will require 50x more power than cloud equivalents five years ago.
To meet this

In December 2025, the UK's National Energy System Operator (NESO) announced the results of its major overhaul of the UK’s grid connection process, removing speculative schemes and introducing a readiness-based system. While this affects all electricity projects, it raises the bar for data centres, which mus

Artificial intelligence (AI) workloads are driving rapid growth in data center power density and energy consumption. Hyperscale and edge facilities supporting AI training and inference are increasingly constrained by power availability and thermal limits. As deployment accelerates, sustainable power delivery ha
