Abstract

Samenvatting:Provides a systematic, practical treatment of DC/DC converters, fromtheir classical roots to the state of the art" Contains information on the latest techniques including voltage-lift,super-lift, and the new cascade prototypes" Introduces more than 100 topologies developed by the authors" Illustrates EMI/EMC reduction and various DC voltage sources" Presents theory and applications using hundreds of figures,discussions, and examplesDC/DC conversion techniques have undergone rapid development in recentdecades. With the pioneering work of authors Fang Lin Luo and Hong Ye,DC/DC converters have now been sorted into their six generations, and bya rough count, over 500 different topologies currently exist, with morebeing developed each year.Advanced DC/DC Converters offers a concise, practical presentation ofDC/DC converters, summarizing the spectrum of conversion technologies andpresenting many new ideas and more than 100 new topologies. The treatmentbegins with background material on DC/DC conversion and discussions onvoltage lift and super-lift converters. It then proceeds through eachgeneration, including the groundbreaking sixth generation--convertersdeveloped by the authors that can be cascaded for high voltage transfergain.More than 320 figures, 60 tables, and 500 formulae allow you to moreeasily grasp the overall structure of advanced DC/DC converters, providefast access to precise data, and help you quickly determine the values ofyour own circuit components. Nowhere else in the literature are DC/DCconverters so logically sorted and systematically introduced. Nowhereelse can you find detailed information on prototype topologies thatrepresent a major contribution to modern power engineering.

Abstract

"Renewable energy systems require a large number of converters/inverters. Many new types of inverters have been created in recent decades, and these circuits will largely improve the power factor and increase the power efficiency for the future. This book covers advances DC/AC inverters that are both concise and useful for engineering students and practicing professionals. It uses 150 diagrams to introduce more than 100 topologies of the advanced inverters originally developed by the authors. The book includes more than 50 new circuits"--

Abstract

The purpose of this book is to describe the theory of Digital Power Electronics and its applications. The authors apply digital control theory to power electronics in a manner thoroughly different from the traditional, analog control scheme. In order to apply digital control theory to power electronics, the authors define a number of new parameters, including the energy factor, pumping energy, stored energy, time constant, and damping time constant. These parameters differ from traditional parameters such as the power factor, power transfer efficiency, ripple factor, and total harmonic distor

Abstract

The purpose of this book is to describe the theory of Digital Power Electronics and its applications. The authors apply digital control theory to power electronics in a manner thoroughly different from the traditional, analog control scheme. In order to apply digital control theory to power electronics, the authors define a number of new parameters, including the energy factor, pumping energy, stored energy, time constant, and damping time constant. These parameters differ from traditional parameters such as the power factor, power transfer efficiency, ripple factor, and total harmonic distortion. These new parameters result in the definition of new mathematical modeling: A zero-order-hold (ZOH) is used to simulate all AC/DC rectifiers. A first-order-hold (FOH) is used to simulate all DC/AC inverters. A second-order-hold (SOH) is used to simulate all DC/DC converters. A first-order-hold (FOH) is used to simulate all AC/AC (AC/DC/AC) converters. * Presents most up-to-date methods of analysis and control algorithms for developing power electronic converters and power switching circuits * Provides an invaluable reference for engineers designing power converters, commercial power supplies, control systems for motor drives, active filters, etc. * Presents methods of analysis not available in other books.

Abstract

This volume on iron-sulfur proteins includes chapters that discuss how microbes, plants, and animals synthesize these complex prosthetic groups, and why it is important to understand the chemistry and biogenesis of iron sulfur proteins. In addition to their vital importance in mitochondrial respiration, numerous iron sulfur proteins are important in maintenance of DNA integrity. Multiple rare human diseases with different clinical presentations are caused by mutations of genes in the iron sulfur cluster biogenesis pathway. Understanding iron sulfur proteins is important for understanding a rapidly expanding group of metabolic pathways important in all kingdoms of life, and for understanding processes ranging from nitrogen fixation to human disease.

Abstract

This volume on iron-sulfur proteins includes chapters that describe the initial discovery of iron-sulfur proteins in the 1960's to elucidation of the roles of iron sulfur clusters as prosthetic groups of enzymes, such as the citric acid cycle enzyme, aconitase, and numerous other proteins, ranging from nitrogenase to DNA repair proteins. The capacity of iron sulfur clusters to accept and delocalize single electrons is explained by basic chemical principles, which illustrate why iron sulfur proteins are uniquely suitable for electron transport and other activities. Techniques used for detection and stabilization of iron-sulfur clusters, including EPR and Mossbauer spectroscopies, are discussed because they are important for characterizing unrecognized and elusive iron sulfur proteins. Recent insights into how nitrogenase works have arisen from multiple advances, described here, including studies of high-resolution crystal structures. Numerous chapters discuss how microbes, plants, and animals synthesize these complex prosthetic groups, and why it is important to understand the chemistry and biogenesis of iron sulfur proteins. In addition to their vital importance in mitochondrial respiration, numerous iron sulfur proteins are important in maintenance of DNA integrity. Multiple rare human diseases with different clinical presentations are caused by mutations of genes in the iron sulfur cluster biogenesis pathway. Understanding iron sulfur proteins is important for understanding a rapidly expanding group of metabolic pathways important in all kingdoms of life, and for understanding processes ranging from nitrogen fixation to human disease.
