Abstract

In this paper, an alternative method to achieve more efficient DC power distribution and voltage regulation for future data centers is proposed. The proposed power delivery architecture is validated with real servers performing two different real-world operations: web traffic management and computation. This paper describes series-stacked power delivery architecture, provides an experimental proof of concept and compares the proposed architecture with the conventional DC power delivery architecture employing a best-in-class power supply unit for servers. Through experimental measurements, we demonstrate up to a 20x reduction in power conversion losses compared to state-of-the-art hardware.
