本文提出了一种为未来数据中心实现更高效的直流功率分配和电压调节的替代方法。通过实际服务器执行两种不同的实际操作：Web流量管理和计算，验证了所提出的功率交付体系结构。本文描述了串联堆叠供电结构，提供了概念的实验验证，并将所提出的结构与采用同类最佳服务器电源单元的传统直流供电结构进行了比较。通过实验测量，我们证明了与最先进的硬件相比，功率转换损耗最多降低了20倍。
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.
