Book Description
As industry power demands become increasingly sensitive, power quality distortion becomes a critical issue. The recent increase in nonlinear loads drawing non-sinusoidal currents has seen the introduction of various tools to manage the clean delivery of power. Power demands of medical facilities, data storage and information systems, emergency equipment, etc. require uninterrupted, high quality power. Uninterruptible power supplies (UPS) and active filters provide this delivery. The first to treat these power management tools together in a comprehensive discussion, Uninterruptible Power Supplies and Active Filters compares the similarities of UPS, active filters, and unified power quality conditioners. The book features a description of low-cost and reduced-parts configurations presented for the first time in any publication, along with a presentation of advanced digital controllers. These configurations are vital as industries seek to reduce the cost of power management in their operations. As this field of power management technology continues to grow, industry and academia will come to rely upon the comprehensive treatment found within this book. Industrial engineers in power quality, circuits and devices, and aerospace engineers as well as graduate students will find this a complete and insightful resource for studying and applying the tools of this rapidly developing field.

Book Description
Power Supply Devices and Systems of Relay Protection brings relay protection and electrical power engineers a single, concentrated source of information on auxiliary power supply systems and devices. The book also tackles specific problems and solutions of relay protection power supply systems and devices, which are often not dealt with in the literature. The author, an experienced engineer with more than 100 patents, draws on his own experience to offer practical, tested advice to readers. A Guide to Relay Protection Power Supply for Engineers and Technicians The first chapter reviews the electronics and primary elements of the system, including transistors, thyristors, optocouplers, logic elements, and relays, and their principles of operation. This background gives staff who service relay protection power supply systems the necessary electronics knowledge to help them work more effectively with the equipment. The next chapters of the book then cover built-in digital protection relay power supplies, battery chargers, accumulator batteries, uninterruptible power supply, and characteristic features of auxiliary DC systems at substations and power plants. The final chapters discuss questions and problems that engineers and technicians may face. These include insulation problems, issues in auxiliary DC power supply such as voltage dips, and electromagnetic disturbances such as blackouts, spikes, and surges. The author also explains how to address them. Suitable for beginners and experienced engineers alike, the book is written for those who work with relay protection systems and with AC and DC auxiliary power systems in power plants and substations. It combines theory and practical recommendations to provide a valuable reference on power supply devices and systems.
