Troubleshooting Switching Power Converters Book Review:

Power Supply design is all about detail. And a large part of that detail lies in the practical domain, largely because of the typically small number of microseconds of switching periods involved, and the even smaller tens of nanoseconds of switch transition times --- all these, in effect accentuating various "second-order" effects, that eventually end up playing prime havoc with "normal" expectations of how the circuit should behave. So not unsurprisingly, even after reading several books, most readers still find themselves no closer to the ultimate goal of designing an actual power supply. Sooner or later, all engineers start realizing the hard fact that designing a switching power supply isn't the trivial task it once seemed to be. But even after years of successfully mastering the underlying theory, the ultimate goal of creating a cost-effective, reliable and commercially viable power supply may still remain a distant dream, since success ultimately hinges on experience. That is, in fact, what clearly differentiates a senior and seasoned power supply engineer from the others --- the ability to navigate and surmount a veritable minefield of tricky issues that can only be learned the hard way, by actual hands-on experience on the job. This book presents practical knowledge the author acquired rather painfully, while working "in the trenches" for several years in major engineering companies scattered across several continents. This is intended to be the mythical senior engineer's "bag of tricks," finally made available in the form of an easy-to-read book on your shelf. This book will make life for the ambitious power supply engineer much simpler --- besides reducing significantly, the rigorous requirement of having to be a senior engineer's protégé for years on end, just to gain a small measure of real success in this field. * A practical presentation that answers the important question: why is my switching converter behaving so differently than what I was expecting on the basis of my paper design? And how do I bridge that huge gap? * For the first time, a systematic and thorough discussion of troubleshooting switching power supplies. * Coverage of AC/DC and DC/DC power supplies. * Bench Evaluation of semiconductor ICs used in power conversion --- describing standard and unusual techniques mastered by the author, while testing similar chips at National Semiconductor. * Detailed coverage of vital topics that haven't been covered by available sources --- grounding systems, the subtleties of component datasheets, and using instruments and probes effectively. * Systematic investigation (type of failure mechanism, topology, etc.) and solutions for 5 years of reported power supply issues on a prominent, public web forum. This approach will ensure that engineers will not repeat the same mistakes. * A unique, readable style: personal and direct; no mystification--- just the plain truth, easily and logically explained, with plenty of pictures, graphs and plots.

Switch Mode Power Converters Book Review:

Switch-Mode Power Converters introduces an innovative, highly analytical approach to symbolic, closed-form solutions for switched-mode power converter circuits. This is a highly relevant topic to power electronics students and professionals who are involved in the design and analysis of electrical power converters. The author uses extensive equations to explain how solid-state switches convert electrical voltages from one level to another, so that electronic devices (e.g., audio speakers, CD players, DVD players, etc.) can use different voltages more effectively to perform their various functions. Most existing comparable books published as recently as 2002 do not discuss closed-loop operations, nor do they provide either DC closed-loop regulation equations or AC loop gain (stability) formulae. The author Wu, a leading engineer at Lockheed Martin, fills this gap and provides among the first descriptions of how error amplifiers are designed in conjunction with closed-loop bandwidth selection. BENEFIT TO THE READER: Readers will gain a mathematically rigorous introduction to numerous, closed-form solutions that are readily applicable to the design and development of various switch-mode power converters. Provides symbolic, closed-form solutions for DC and AC studies Provides techniques for expressing close-loop operation Gives readers the ability to perform closed-loop regulation and sensitivity studies Gives readers the ability to design error amplifiers with precision Employs the concept of the continuity of states in matrix form Gives accelerated time-domain, steady-state studies using Laplace transform Gives accelerated time-domain studies using state transition Extensive use of matrix, linear algebra, implicit functions, and Jacobian determinants Enables the determination of power stage gain that otherwise could not be obtained

Nonlinear Control and Operation of Dc to Dc Switching Power Converters Book Review:

Conventional control of switching power conversion is based on a linear model of the system, which limits its scope and performance. This thesis addresses a family of control and operation issues that arise from the nonlinear nature of the switching power conversion. The focus is on dc to dc power converters with a small number of states. Nonlinear noise analysis of conventional feedback has been performed to evaluate this important aspect of converter performance. Alternative schemes are developed that reduce noise susceptibility, reduce effects of source and load disturbance, and improve system operation. A nonlinear control scheme called sensorless current mode (SCM) control has been developed that emulates current mode control without current sensing. SCM has very significant advantages in dynamic range and noise susceptibility. Optimal control approaches to switching power conversion has been explored. Optimization of a nonmonotonic tuning problem has also been explored. A generalized tuning scheme has been developed and implemented for practical converters with excellent results.

A Hundred Solved Problems in Power Electronics Book Review:

A Hundred Solved Problems in Power Electronics presents a large collection of questions and their answers for someone who is interested in understanding the operation principle of power electronics converters. By creating a real engineering environment around the question, the goal of this book is to contribute on the development of a qualified electrical engineering workforce. By using engineering language and technical terminology (jargon), this book deals primarily with the challenge of designing power converters for specific applications. This includes, but is not limited to, personal computer power supply, regulated voltage source, and interconnection of renewable energy sources. Since engineering is the application of science to practical use, the link with a real world activity fills the gap between theory and practical application and increases the curiosity of the students. Before each question there is a short text explaining the purpose of that specific problem and how it is associated with real world conditions. The majority of the questions in this book follow a logical sequence, which is an attempt to demonstrate the step-by-step process of a power electronics converter design. Indeed, the purpose of this book is to present a more exciting type of question and show how the theory in power electronics is related to real world problems. Rather than just plugging in numbers for a given equation, this book shows practical examples on how to use scientific and technical knowledge to make, operate, and maintain complex systems. Although engineering is one of the professions that actually allows someone to build and create something that could eventually change the life of people (e.g., personal computer or satellite), there is sometimes a lack of motivation from the students in the classroom. It is quite clear that the students are comfortable with math, especially at the senior level. Therefore, the lack of motivation is not due to background deficiency. Instead, the discouragement increases when students do not correlate the subject taught with their future professional activities. Also, the way traditional lectures are set up--with theory presentation followed by examples where students just need to plug in the given data into specific equations--does not keep students' interest and attention. In fact, the moment of solving a specific problem, in a traditional way to teach, comes down to this question: what's the equation that I need to use to plug these given numbers? This is stimulated by the way the problems are designed. We hope that this book offers an alternative on how the students view and address the problems in power electronics. This book is a desirable didactic material to be employed as a reference book instead of a text book (from which the instructor prepares his/her lecture). Notice that the terminology used in A Hundred Solved Problems in Power Electronics is not necessarily the same as the one seen in either the text book or from the instructor lectures. This is actually a benefit for the students in electrical engineering since they will learn different terms for the same component or electrical element. Certainly this difference in nomenclature will be seen by the students as an advantage when they are reading technical datasheets and realize that manufacturers often use different terms for the same information. By dividing this book into five parts, the authors compile the solved problems into the following categories: 1) Converters with power diodes 2) SCR converters 3) Dc-dc converters 4) Dc-ac converters 5) Isolated dc-ac converters Such a book structure follows the same sequence of topics as most power electronics books in the technical literature, which simplifies the use of A Hundred Solved Questions in Power Electronics as a recommended book in parallel with other references.
