Demystifying Switching Power Supplies – Raymond A. Mack, Jr. – 1st Edition


This is a crash course in the fundamental theory, concepts, and of . It is designed to quickly prepare engineers to make key decisions about supplies for their projects.

Intended for readers who need to quickly understand the key points of switching , this book covers the 20% of the topic that engineers use, 80% of the time.

Unlike existing switching power supply 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 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. Engineers, whose main design responsibilities are in other areas, will better understand the strengths and weaknesses of switching power supplies and whether such supplies are appropriate for their projects. They will be able to give more meaningful design requirements and specifications to those who design switching power supplies.
