一种基于模块化部分功率变换器的直流供电服务器不间断电源方案

This article proposes a novel partial power converter based uninterruptible power supply (PPC-UPS) scheme for dc power feeding servers in data centers, in which a server load and its local backup battery are connected in series and compactly integrated to a common dc bus through one PPC. The proposed PPC-UPS scheme is modularized and distributed in multiple dc loads of a data center, with high sca...
