advanced dc dc converters second edition pdf

Preface to the Second Edition

The first edition of this book was published in 2004. Since then, we have received a great deal
of feedback from readers around the world. In this second edition, we would like to retrench
and update the contents to include new techniques developed over the past 12 years, improve
the book based on readers’ suggestions, and correct some typographical errors.

Super-lift technique is an outstanding achievement in DC/DC conversion technology. As
new developments, the ultra-lift technique and hybrid split capacitor/split inductor applied in
super-lift Luo-converters are introduced in Chapters 7 and 8 in this edition. They are superior
to the super-lift technique in achieving higher-voltage transfer gain. Some industrial
applications demonstrate their versatile and powerful characteristics.

Mathematical modeling for power DC/DC converters is a historical problem
accompanying DC/DC conversion technology since the 1940s. Traditional mathematical
modeling is not available for complex structure converters because the differential equation
order of these converters is very high.

We have theoretically defined a new concept—the energy factor (EF)—and demonstrated the relations between EF and the mathematical modeling for power DC/DC converters and applied the modeling method in two converters in Chapter 9. This investigation is very helpful for the system design and the prediction of DC/DC converter characteristics.

Organization of This Book

This book is organized into 21 chapters. The knowledge on DC/DC conversion is introduced
in Chapter 1 and that on voltage-lift converters in Chapter 2. Chapters 3, 4, 5 and 6 present the
four-series super-lift converters. Chapters 7 and 8 are added to introduce the new
developments in DC/DC converters: the ultra-lift Luo-converter and the split capacitor/split
inductor techniques in positive-output super-lift Luo-converters. Chapter 9 discusses the novel
mathematical modeling concept and method for DC/DC converters.

Chapter 10 introduces second-generation converters and Chapter 11 the third-generation converters. Chapters 12 and 13 focus on two-series multiple-lift push-pull switched-capacitor converters. Chapters 14, 15, 16, 17, 18 and 19 cover fourth-, fifth-, and sixth-generation converters. Chapter 20 introduces various DC voltage sources, and Chapter 21 includes the gating-signal generator and
electromagnetic interference (EMI)/electromagnetic compatibility (EMC) with some applications.
