This book addresses topics specific to the application of power electronics to telecom systems. It follows the power flow from national grid down to the last low-voltage high current requirement of a processor. Auxiliary equipment requirements, such as uninterruptible power supplies, storage energy systems, or charging systems, are explained, along with peculiar classification or suggestions for usage. The presentation of each telecom power system is completed with a large number of practical examples to reinforce new material.

Straightforward, systematic approach for designing reliable dc power systems for telecommunications Here is a must-have resource for anyone responsible for designing, installing, and maintaining telecommunications systems. The text explains how to design direct current (dc) power systems that operate at nominal voltages of 24 and 48 volts dc, use lead-acid batteries, and are installed in public network telecommunications systems and other exclusive-use environments. Rather than train readers to design systems by rote, the author gives readers the skills and knowledge to perform systematic analyses to make the best choices based on several economic, operational, electrical, and physical considerations. Written in a straightforward style that avoids unnecessary jargon and complex mathematics, the text covers all the essentials of dc power systems for telecommunications: * Detailed descriptions of the seven major system components: Rectifier/charger System, Battery System, Charge Bus, Discharge Bus, Primary Distribution System, Secondary Distribution System, and Voltage Conversion System * Detailed descriptions include design equations, reference tables, block diagrams, and schematics * Design procedures to help readers select the most appropriate power system elements, such as buses, wiring, overcurrent protection, rectifiers, and batteries * Application of the American National Standards Institute's telecommunications industry standards and other relevant standards, practices, and codes * Strategies for dealing with voltage drop in distribution and battery circuits as well as guidance for sizing circuit wiring to meet voltage drop and current rating requirements * In-depth discussions that focus on the types of lead-acid batteries used in telecommunications and their applications Throughout the text, examples demonstrate how theory is applied to real-world telecommunications systems. Some 330 illustrations and more than 100 tables are also provided to help readers visualize and better understand complex systems. Design and application examples and accompanying solutions help readers understand the design process and use their new skills. In summary, engineers and technicians in the telecommunications industry will find all the resources they need to design reliable dc power systems.

This book looks at the challenge of providing reliable and cost-effective power solutions to expanding communications networks in remote and rural areas where grid electricity is limited or not available. It examines the use of renewable energy systems to provide off-grid remote electrification from a variety of resources, including regenerative fuel cells, ultracapacitors, wind energy, and photovoltaic power systems, and proposes a powerful hybrid system that can replace the need and high operation costs of batteries and diesel powered electric generators. Analyzes types of communications stations and their rate of consumption of electrical power; Presents brief descriptions of various types of renewable energy; Investigates renewable energy systems as a source for powering communication stations.

This book introduces the technical foundations and tools for estimating the power consumption of internet networks and services, including a detailed description of how these models are constructed and applied. Modeling the Power Consumption and Energy Efficiency of Telecommunications Networks can be used to gain insight into the construction of mathematical models that provide realistic estimates of the power consumption of internet networks and services. This knowledge enables forecasting the energy footprint of future networks and services to integrate sustainability and environmental considerations into network planning and design. FEATURES Provides the motivation for developing mathematical models for telecommunications network and service power consumption and energy efficiency modeling Presents factors impacting overall network and service power consumption Discusses the types of network equipment and their power consumption profiles Reviews the basics of power modeling, including network segmentation, traffic forecasting, top-down and bottom-up models, wired and wireless networks, data centers and servers Explores the application of energy efficiency metrics for equipment, networks, and services This book is aimed at students and technologists as well as technology managers and policy makers. This book will be of value to any organization that wishes to estimate the energy footprint of the use of information and communications technologies. This book can also be integrated into a course on the sustainability of information and communications technologies.
