Digital Power Electronics and Applications Review

Average Reviews:

(More customer reviews)Nothing new. Just repeat from old text books under a new book heading. All theory, no practical working examples. A flop attempt in a difficult engineering area.
Th book will sell because of its name, but once you read it, you will get the same above feeling as mine.

The purpose of this book is to describe the theory of Digital Power Electronics and its applications. The authors apply digital control theory to power electronics in a manner thoroughly different from the traditional, analog control scheme. In order to apply digital control theory to power electronics, the authors define a number of new parameters, including the energy factor, pumping energy, stored energy, time constant, and damping time constant.These parameters differ from traditional parameters such as the power factor, power transfer efficiency, ripple factor, and total harmonic distortion.These new parameters result in the definition of new mathematical modeling:. A zero-order-hold (ZOH) is used to simulate all AC/DC rectifiers.. A first-order-hold (FOH) is used to simulate all DC/AC inverters.. A second-order-hold (SOH) is used to simulate all DC/DC converters.. A first-order-hold (FOH) is used to simulate all AC/AC (AC/DC/AC) converters. * Presents most up-to-date methods of analysis and control algorithms for developingpower electronic converters and power switching circuits* Provides an invaluable reference for engineers designing power converters, commercialpower supplies, control systems for motor drives, active filters, etc.* Presents methods of analysis not available in other books.

Complex Analysis (Universitext) Review

Average Reviews:

(More customer reviews)This book was originally written in German, and the German version is just incredible: a real gem. Good reason to translate it! Unfortunately, this is one of the worst translations from German I have seen. Some of it is just awkward grammar, which the reader may be able to ignore. But, there are also some words and phrases which are translated incorrectly.
For example "Paragraphen" in German does not mean paragraph in English, it means section. But in this book it is translated as paragraph. Try looking for something at the end of a paragraph or in the previous paragraph, when you should actually be looking at the end of the section or in the previous section. An example of this can be found in the explanation of the addition theorem for complex exponents (p. 27). The English text claims there is a remark concerning this at the end of the "paragraph." The paragraph ends and there is no remark. Turn to the end of the section (p. 31) and you will find the remark just above the exercises.
My advice is, if you can read German, get the German version! If you can't read German, you can still get the English version, but you will have to be very patient with the mistakes incurred in the translation (not to be found in the German original). If you own this book, you should systematically go through it and replace "paragraph" everywhere with "section." Most of the other translation mistakes can be figured out by context.
