| dc power system design for telecommunications: DC Power System Design for Telecommunications Whitham D. Reeve, 2006-10-25 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. |

| dc power system design for telecommunications: Industrial Power Systems Shoaib Khan, Sheeba Khan, Ghariani Ahmed, 2018-10-03 The modernization of industrial power systems has been stifled by industry's acceptance of extremely outdated practices. Industry is hesitant to depart from power system design practices influenced by the economic concerns and technology of the post World War II period. In order to break free of outdated techniques and ensure product quality and continuity of operations, engineers must apply novel techniques to plan, design, and implement electrical power systems. Based on the author's 40 years of experience in Industry, Industrial Power Systems illustrates the importance of reliable power systems and provides engineers the tools to plan, design, and implement one. Using materials from IEEE courses developed for practicing engineers, the book covers relevant engineering features and modern design procedures, including power system studies, grounding, instrument transformers, and medium-voltage motors. The author provides a number of practical tables, including IEEE and European standards, and design principles for industrial applications. Long overdue, Industrial Power Systems provides power engineers with a blueprint for designing electrical systems that will provide continuously available electric power at the quality and quantity needed to maintain operations and standards of production. |

| dc power system design for telecommunications: DC Power Supplies Nihal Kularatna, 2018-10-03 As we increasingly use electronic devices to direct our daily lives, so grows our dependence on reliable energy sources to power them. Because modern electronic systems demand steady, efficient, reliable DC voltage sources—often at a sub-1V level—commercial AC lines, batteries, and other common resources no longer suffice. New technologies also require intricate techniques to protect against natural and manmade disasters. Still, despite its importance, practical information on this critical subject remains hard to find. Using simple, accessible language to balance coverage of theoretical and practical aspects, DC Power Supplies, Power Management and Surge Protection details the essentials of power electronics circuits applicable to low-power systems, including modern portable devices. A summary of underlying principles and essential design points, it compares academic research and industry publications and reviews DC power supply fundamentals, including linear and low-dropout regulators. Content also addresses common switching regulator topologies, exploring resonant conversion approaches. Coverage includes other important topics such as: Control aspects and control theory Digital control and control ICs used in switching regulators Power management and energy efficiency Overall power conversion stage and basic protection strategies for higher reliability Battery management and comparison of battery chemistries and charge/discharge management Surge and transient protection of circuits designed with modern semiconductors based on submicron dimension transistors This specialized design resource explores applicable fundamental elements of power sources, with numerous cited references and discussion of commercial components and manufacturers. Regardless of their previous experience level, this information will greatly aid designers, researchers, and academics who, study, design, and produce the viable new power sources needed to propel our modern electronic world.
