48 V data center power, at bench scale

A small-scale model of the 48 V power architecture used to feed AI hardware in data centers.

Problem

AI hardware draws a lot of power in a small space, and delivering that power efficiently is becoming a limit of its own. Data centers are moving from 12 V to 48 V distribution: for the same power, four times the voltage means a quarter of the current, and conduction losses (I²R) drop by a factor of sixteen.

Approach

A small bench model of the chain: a 48 V bus, a converter that steps it down for the load, and careful measurements of efficiency and losses at each stage.

Plan

  • Literature notes on 48 V architectures
  • Converter selection and schematic
  • Building and measuring at bench scale

This project starts after the first stages of the AI accelerator.
