POWER ELECTRONICS TUTORIAL EXERCISES

This textbook is providing the students and professors with a variety of properly selected step-by step worked examples in order to assist them of understanding a power electronics course. Each chapter of this textbook consists of a number of worked examples which extend the reader’s experience in problem solving and to help develop a deeper understanding of the subject. Chapter 1 is a unique Chapter because presents in 30 Tables the most wanted information that a student and a professor needs in order to analyze different power electronics problems. This information includes key-waveforms, expressions, rms and dc values of different well known waveforms and their respective frequency spectrum (i.e. Fourier analysis). The worked examples outlined in this textbook are carefully selected to coincide with the didactic material of an introductory course in power electronics. The step-by-step examples are not examples that are used only for plugging numbers but are continuation of the power electronics theory with waveforms, relations and results for specific industrial application so that the reader to understand the specific theory and at the same time to create the appropriate feedback remarks. Moreover, in the appendix of this textbook 100 multiple choice questions are presented with their respective answers.The theoretical results obtained in the worked examples are verified by the respective simulation ones making the results more rigid and acceptable by the reader. There are 50 simulation results out of 180 worked examples that strengthen the understanding of the examples. The most of the worked examples are oriented towards applications to Uninterruptible Power Supply (UPS) systems, switched mode power supplies, renewable energy sources, Static VAr compensators, power semiconductor devices, passive and active filtering and motor drive systems.This textbook, which is consisted of 200 worked examples and 100 multiple choice questions, has all the necessary material for coursework, assignments and final exam preparation.The 200 worked examples presented in this textbook are divided into the following 12 chapters: Chapter 1: Introduction to power electronics technology with 27 tables of useful information and 10 worked examples.Chapter 2: Circuits with diodes and switches with 16 worked examplesChapter 3: Single-phase half-wave thyristor rectifiers with 15 worked examplesChapter 4: Diode rectifiers with 25 worked examplesChapter 5: Thyristor rectifiers with 31 worked examplesChapter 6: Inverters with 30 worked examplesChapter 7: Dc-dc converters with 16 worked examplesChapter 8: Ac voltage controllers and static VAr compensators with 10 worked examplesChapter 9: PWM rectifiers with 10 worked examplesChapter 10: Power semiconductor devices with 14 worked examplesChapter 11: Passive and Active filters with 12 worked examplesChapter 12: Introduction to motor drive systems with 17 worked examplesAPPENDIX: 100 multiple choice questions with their respective answersThe majority of the 200 worked examples in this textbook 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 textbook is to present a more exciting type of questions and show how the theory in power electronics is related to real world problems.
