The Design Guide Trilogy of Magnetics Würth Elektronik launches now the 4th edition of the
design guide Trilogy of Magnetics in the German language. The English edition will be
published in April 2009. The design guide for EMI filter design and SMPS & RF design circuit is
completely revised newly structured and covers a multitude of new components and
applications. The design guide is divided into the following the chapters: Basics Principles
Components and Applications. A keyword index as well as a formulary closes the book. The
objective of the design guide Trilogy of Magentics is to practically familiarize customers
and users with the characteristics and applications of inductive components. The design guide
was published 8 years ago for the first time and is now a standard work for lots of development
departments und universities. The book has sold over 15 000 copies in the last 8 years. In the
4th edition the explanation of old techniques and components was extracted to have more room
for new components and applications. Notably a multitude of external authors from our customer
base and our well-known manufacturers passed on their experiences and solutions in the Basic
Principles and Applications section. The following articles are exemplary highlights: -
Calculation dimensioning and construction of customer-specific transformers (Do-it-yourself
transformer design) - A transformer's effect on return loss - Class-D amplifier - An
introduction to frequency compensation - Basic principles of Ethernet & Power-over-Ethernet
Furthermore the Trilogy includes over 200 practical examples to the following topics: o Filter
circuits o Audio circuits o Video circuits o Interfaces o HF circuits o Motor control units o
SMPS o Line filter o Power supply
