Power supplies are of vital importance in any electronic device, and switching power supplies are the predominant technology in this field -- deriving their name from the way in which they switch between various power handling circuits to produce a steady, reliable power supply. Switching power supplies are rapidly replacing older linear power supplies because of their greater efficiency, improved voltage regulation, and smaller size/lower weight.
Raymond A. Mack, Jr.'s Demystifying Switching Power Supplies is a "crash" course in the fundamental theory, concepts, and terminology of switching power supplies. It is designed to quickly prepare engineers to make key decisions about power supplies for their projects. Unlike existing switching power supply books that deal strictly with design issues, this book also recognizes the growing importance of "off-the-shelf" commercial switching power supplies, giving readers the background necessary to select the right commercial supply.
This book covers the core essentials of power supply theory and design while keeping mathematics to the absolute minimum necessary. Special attention is given to the selection of appropriate components, such as inductors and transformers, to ensure safe and reliable operation. This book will give engineers a better understanding of the strengths and weaknesses of switching power supplies, and whether such supplies are appropriate for their projects.
