Synchronous and Resonant DC/DC Conversion Technology, Energy Factor, and Mathematical Modeling


Book Description

Numbers alone are enough to describe the importance of DC/DC converters in modern power engineering. There are more than 500 recognized topologies, with more added each year. In their groundbreaking book Advanced DC/DC Converters, expert researchers Luo and Ye organized these technologies into six generations and illustrated their principles and operation through examples of over 100 original topologies. In chapters carefully drawn from that work, Synchronous and Resonant DC/DC Conversion Technology, Energy Factor, and Mathematical Modeling provides a focused, concise overview of synchronous and multiple-element resonant power converters. This reference carefully examines the topologies of more than 50 synchronous and resonant converters by illustrating the design of several prototypes developed by the authors. Using more than 100 diagrams as illustration, the book supplies insight into the fundamental concepts, design, and applications of the fifth (synchronous) and sixth (multiple-element resonant) converters as well as DC power sources and control circuits. The authors also discuss EMI/EMC problems and include a new chapter that introduces the new concept of Energy Factor (EF) and its importance in mathematical modeling as well as analyzing the transient process and impulse response of DC/DC converters. Synchronous and Resonant DC/DC Conversion Technology, Energy Factor, and Mathematical Modeling supplies a quick and accessible guide for anyone in need of specialized information on synchronous and resonant DC/DC converter technologies.




Advanced DC/DC Converters


Book Description

DC/DC conversion techniques have undergone rapid development in recent decades. With the pioneering work of authors Fang Lin Luo and Hong Ye, DC/DC converters have now been sorted into their six generations, and by a rough count, over 800 different topologies currently exist, with more being developed each year. Advanced DC/DC Converters, Second Edition offers a concise, practical presentation of DC/DC converters, summarizes the spectrum of conversion technologies, and presents new ideas and more than 200 new topologies. Beginning with background material on DC/DC conversion, the book later discusses both voltage lift and super-lift converters. It then proceeds through each generation, including the groundbreaking sixth generation—converters developed by the authors that can be cascaded for high voltage transfer gain. This new edition updates every chapter and offers three new chapters. The introduction of the super-lift technique is an outstanding achievement in DC/DC conversion technology, and the ultra-lift technique and hybrid split-capacitor/inductor applied in Super-Lift Luo-Converters are introduced in Chapters 7 and 8. In Chapter 9, the authors have theoretically defined a new concept, Energy Factor (EF), researched the relations between EF and the mathematical modelling for power DC/DC converters, and demonstrated the modeling method for two converters. More than 320 figures, 60 tables, and 500 formulae allow the reader to more easily grasp the overall structure of advanced DC/DC converters, provide fast access to precise data, and help them to quickly determine the values of their own circuit components.

DC Power Supplies


Book Description

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.
