Eric Monmasson Power Electronic Converters. PWM Strategies and Current Control Techniques

Eric Monmasson Power Electronic Converters. PWM Strategies and Current Control Techniques

A voltage converter changes the voltage of an electrical power source and is usually combined with other components to create a power supply. This title is devoted to the control of static converters, which deals with pulse-width modulation (PWM) techniques, and also discusses methods for current control. Various application cases are treated. The book is ideal for professionals in power engineering, power electronics, and electric drives industries, as well as practicing engineers, university professors, postdoctoral fellows, and graduate students.

Steven Blume W. High Voltage Protection for Telecommunications

Steven Blume W. High Voltage Protection for Telecommunications

Sets forth the steps needed to protect critical telecommunications circuits from power faults and lightning in high voltage environments The need to protect telecommunications circuits from power faults and lightning has never been greater: when power outages or system disturbances occur, reliable telecommunications are essential. With this book as their guide, readers will know what they need to do (and not do) to protect critical telecommunications circuits and equipment located in high voltage environments such as electrical power plants, substations, and power towers. Moreover, the book explains how to get the job done safely, detailing the proper implementation of safety procedures and the use of protective equipment to eliminate or minimize risk. Setting the foundation, the book begins with an overview of the problem, key issues, industry standards, and safety concerns. Next, it covers: Definitions and fundamentals of electric power systems, with regard to HVPT applications Causes, boundary conditions, and calculations of ground potential rise Critical telecommunications circuits that must be protected in high voltage environments Protection schemes and equipment to resolve ground potential rise problems Effective installation and testing of high voltage interface equipment Personal safety for telecommunications personnel working with equipment in high voltage environments Throughout the book, the author refers to accepted industry standards and best practices. Written by one of the most respected professional trainers in the telecommunications industry, High Voltage Protection for Telecommunications can be used for professional training courses or self-study. It will enable readers to protect critical data and voice communications circuits from high voltage events and protect themselves during equipment installation and maintenance.

А. А. Максуров Coordination in legal systems of the countries of Europe. Part I

For the first time applied a coordination approach to the consideration of legal phenomena, thanks to which one can explore legal phenomenon from a new angle of view. The above mentioned gives opportunity in this case to improve the effectiveness of legal action. Usually the coordination rules of law are not the subject of a separate study. Such a study performed by the author on the example of the legislation of the countries of Europe, using a wide range of legal material. The research allowed to develop recommendations for improving the effectiveness of law due to the streamlining of coordination norms. Made of demarcation rules on the coordination and norms of cooperation, collaboration and other forms of interaction. Updated legal terminology. The proposed use of the coordination rules to certain legislative acts of the countries of Europe.

Calvin Dytham Choosing and Using Statistics. A Biologist's Guide

Choosing and Using Statistics remains an invaluable guide for students using a computer package to analyse data from research projects and practical class work. The text takes a pragmatic approach to statistics with a strong focus on what is actually needed. There are chapters giving useful advice on the basics of statistics and guidance on the presentation of data. The book is built around a key to selecting the correct statistical test and then gives clear guidance on how to carry out the test and interpret the output from four commonly used computer packages: SPSS, Minitab, Excel, and (new to this edition) the free program, R. Only the basics of formal statistics are described and the emphasis is on jargon-free English but any unfamiliar words can be looked up in the extensive glossary. This new 3rd edition of Choosing and Using Statistics is a must for all students who use a computer package to apply statistics in practical and project work. Features new to this edition: Now features information on using the popular free program, R Uses a simple key and flow chart to help you choose the right statistical test Aimed at students using statistics for projects and in practical classes Includes an extensive glossary and key to symbols to explain any statistical jargon No previous knowledge of statistics is assumed
