Download Power Electronics Converters and Regulators Third Edition by Branko L. Dokić easily in PDF format for free 


Foreword 
The book “Power Electronics” by Branko L. Dokić and Branko Blanuša contains ten chapters, and deals with the most significant items of power electronics. It is well organized with lot of examples, figures, and tables. The first chapter is “Introduction.” In this chapter basic elements, as well as some circuits and components used in power electronics are briefly presented. Chapter 2 covers basic semiconductor components, “Diodes and Transistors,” and particularly covers their use as switches in power electronics circuits. Chapter 3 is focused on “Regenerative Switches.” The description is wide and detailed and this chapter may be of interest not only for students, but also for professionals who use these components in practice.




Chapter 4 is “PWM DC/DC Converters.” The converters are classified. All basic topologies of these converters are analyzed in detail in both continuous current mode (CCM) and discontinuous current mode (DCM). “Control Modules” are presented in Chap. 5. This chapter contains a number of control circuits used in power electronics. This chapter may be of interest not only for professionals in the field of power electronics, but also in related fields such as automotive control, pulse electronics, etc.




Chapter 6 covers “DC/AC Converters–Inverters”. This chapter is comprehensive and covers the most important converter topologies and the most common used control techniques, such as selective harmonic elimination, unipolar and bipolar PWM technique, and space vector modulation. The next chapter is AC/DC converters, i.e., rectifiers. This chapter contains all basic topologies from uncontrolled half bridge and full bridge rectifiers to controlled thyristor and transistor ones. Also, some commonly used control techniques are presented.




PWM rectifiers and their applications are also discussed. Two previous chapters are followed by the eighth chapter, which covers “AC/ AC Converters.” The chapter describes single-phase and three-phase AC/AC voltage converters and both direct and indirect frequency AC/AC converters. Also, an overview of matrix converters and their applications is presented in this chapter. Chapter 9 contains a comprehensive description of “Resonant Converters.” Basic topologies are covered; series resonant converters, parallel resonant converters, series–parallel converters, class E resonant converters, zero voltage and zero current switching converters, and some control circuits used in resonant converters. Finally, Chap. 10 covers multilevel converters. Basic topologies of DC/DC and DC/AC multilevel converters are presented.

Also, some widely used control techniques, such as multilevel PWM, space vector modulation, space vector control, and select


ive harmonic elimination, are briefly discussed in this chapter. Every chapter contains a set of solved problems that facilitate understanding of the related field.
Also, every chapter is concluded with a list of problems from the presented topics. Overall, the impression is that the book presents a comprehensive coverage of power electronics. It covers a wide range of topics relevant to power electronics. So, it might be used both as a textbook for students and as a reference book for practicing engineers. In my opinion, there is a significant academic and theoretical contribution made by this book. Therefore, I am glad to recommend the book “Power Electronics” by Branko L. Dokić and Branko Blanuša to be published.
