Abstract

A higher voltage direct-current (HVDC) power feeding system for data centers has many advantages and is presently being studied in many countries. This system is composed of a rectifier, power distribution cabinet (PDC), batteries, and ICT equipment, and the configuration is similar to a -48-V DC power feeding system. The power feeding voltage is about 400 V. We developed a prototype of an HVDC power feeding system using commercial fuses in 2008. A prototype of a power distribution cabinet and fuses were developed in 2009. We conducted a basic experiment and confirmed that the characteristics of our prototype are stable. In this paper, we describe the advantages and development of an HVDC power feeding system and the examination progress of standardization.
