High efficiency power feeding systems are effective solutions for reducing the ICT power consumption with reducing power consumption of the ICT equipment and cooling systems. A higher voltage direct current (HVDC) power feeding system prototype was produced. This system is composed of a rectifier equipment, power distribution unit, batteries, and the ICT equipment. The configuration is similar to a -48 V DC power supply system. The output of the rectifier equipment is 100 kW, and the output voltage is 401.4 V. This paper present the configuration of the HVDC power feeding system and discuss its basic characteristics in the prototype system.
