Würth Elektronik Trilogy of Magnetics textbook — fifth edition

Würth Elektronik has published the fifth edition of its Trilogy of Magnetics textbook. The focal point of the practically oriented technical book lies on application circuits and the selection of passive components and layout recommendations in special consideration of EMC aspects.

The book is divided into several sections. ‘Basic Principles’ describes the most important physical laws and principles of the inductance components, equivalent circuit diagrams and simulation models to give the reader an overview of the fundamental principles in this thematic complex of electronics. ‘Components’ presents inductive components with their particular properties and specific areas of application: EMC components, inductors, transformers, HF components, surge suppression, shielding materials and capacitors. ‘Applications’ goes on to give the reader a comprehensive overview of the principles of filter circuits as well as numerous industrial applications, accompanied by detailed descriptions of original installations.

The fifth revised edition gives in-depth insights into the topic of simulation. In this section, the theoretic aspects dealt with in the preceding ones are brought together to better illustrate their interrelationships. This includes a presentation of filtering principles, which has been expanded to include applications in higher frequency ranges, transformer equivalent circuits, Ethernet and Power-over-Ethernet ports, basics of the switched-mode power supply and wireless power transmission as well as basic RF principles.

The company has expanded a number of the chapters and added extra ones in order to give more space to the ever-growing importance of aspects like wireless energy transmission, RF, energy harvesting and SiC (silicon carbide) and GaN (gallium nitride) switching transistors. Detailed information is also included on the skin and proximity effect and on AC losses.
