This book of problems with worked solutions is designed to provide practice in problem solving for students on undergraduate and HND programmes in Electronics. It may be used as a stand-alone book or as a companion volume to Electronics by Crecraft, Gorham and Sparkes (Chapman & Hall, 1992)
Many changes have been made in this edition, first to the nomenclature so that the book is in agreement with the International System of Units (S. I. ) and secondly to the circuit diagrams so that they conform to B. S. S. 3939. The book has been enlarged and now has 546 problems. Much more emphasis has been given to semiconductor devices and transistor circuits, additional topics and references for further reading have been introduced, some of the original problems and solutions have been taken out and several minor modifications and corrections have been made. It could be argued that thermionic-valve circuits should not have been mentioned since valves are no longer considered important by most electronic designers except possibly for very high power or voltage applications. Some of the original problems on valves and valve circuits have been retained, however, for completeness because the material is still present in many syllabuses and despite the advent and prolification of solid-state devices in recent years the good old-fashioned valve looks like being in existence for a long time. There are still some topics readers may expect to find included which have had to be omitted; others have had less space devoted to them than one would have liked. A new feature of this edition is that some problems with answers, given at the end of each chapter, are left as student exercises so the solutions are not included. The author wishes to thank his colleagues Professor P. N.
Aims of the Book:The foremost and primary aim of the book is to meet the requirements of students pursuing following courses of study:1.Diploma in Electronics and Communication Engineering(ECE)-3-year course offered by various Indian and foreign polytechnics and technical institutes like city and guilds of London Institute(CGLI).2.B.E.(Elect.& Comm.)-4-year course offered by various Engineering Colleges.efforts have beenmade to cover the papers:Electronics-I & II and Pulse and Digital Circuits.3.B.Sc.(Elect.)-3-Year vocationalised course recently introduced by Approach.
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.
This companion volume to Electrical Engineering License Review presents the main book's end-of-chapter problems with detailed step-by-step solutions. A sample exam, also with step-by-step solutions, is included. 100% problems and solutions.
Accompanying CD-ROM contains Delmar Learning's Electronics into the Future product with multimedia presentations, Excel templates, MultiSIM circuit files, and a copy of Textbook edition of MultiSIM.
