Preface

The first edition of the book was one of the elements of my habilitation (a qualification above a Ph.D., which is a necessary step for obtaining the title of a professor in Poland and other European countries), and as a result it was subsequently very carefully reviewed by four reviewers. The habilitation was a success. Using the insightful comments from my reviewers, I have improved the current version and eliminated some typographic errors that were initially overlooked. This book is based on the first edition of the book and besides some changes to the previous material, there are some new elements I include in the new edition. In particular, I add more MATLAB listings, which would further complement and enrich the text by providing worked examples of the solutions proposed in the book. More figures are added and all the existing ones are revised and in color. My new solution for a shunt active power filter is also included in the new edition. All those changes are introduced in the Chapters from the first edition. This book also includes a new Chapter considering selected problems of simulation of power electronic systems together with digital control circuits. These simulations are conducted using MATLAB and PSIM. In the case of the PSIM programs, the considered methods use C code for describing the digital control algorithm. I have written this book in his endeavor to abide by the following maxim nulla dies sine linea $ nie ma dnia bez kreski $ not a day without a line drawn (Apelles, Greek painter, flourished 4th century bc). However, this is not always easily achieved.
