A Review of the Power Distribution System in the Telecommunications Sector

Abstract

The telecommunications sector consumes a significant amount of power from the electric utility grid for its functioning. In a typical telecommunications center, about half the energy consumed is delivered to the load, with the rest is lost in power conversion, distribution and cooling processes. Higher voltage DC is, thus being proposed as an energy efficient distribution option.This paper takes a look at the -48 V power distribution widely used for providing power to telecommunication equipment, and at the methodology used for grounding and bonding of both the power system and the powered telecommunication system. An analysis of the benefits of the +380V DC power distribution system compared to the current -48V DC power supply system in telecommunications sector is also presented. High-frequency AC (HFAC) power distribution systems have also been the subject of great interest. This paper also presents a review of the different HFAC power distribution architectures and is focused on the HFAC power architectures and topologies for the telecommunications system. This paper also presents the concept of green telecommunication networks and provides

A comprehensive review of distributed power system architecture for telecom and datacenter applications

“…In order to support the computing infrastructure, each data center requires a few MW of power, a very large data center requires 10 MW of power. It is anticipated to grow in the future to 50 MW [2], [3].…”
