Many amateurs think of power supplies simply as boxes that provide stable DC voltage at the flick of a switch. There is much more going on behind the scenes. In Power Supplies Explained, Paul Lee, G3ZKO, clearly explains what is happening inside the wide range of power supplies available today—and how to choose the best type for a given application.
This new edition of what has become an internationally acclaimed bestseller, has been thoroughly updated with clearer explanations and expanded content. New material includes a description of the currently favored method for high-efficiency power factor correction, the Totem Pole PFC circuit; expanded coverage of the latest wide band-gap semiconductors; and a section on digital control of power supplies.
Readers will find detailed chapters covering traditional linear power supplies as well as a wide range of switched-mode designs, from simple buck converters to the latest off-line, high-efficiency topologies. Worked examples are based on typical amateur radio requirements and, in many cases, reflect versions of commercial products the author has successfully designed. Additional chapters explore magnetics theory, control loops, EMC considerations, practical construction techniques, test equipment, and more. High-voltage power supplies are also covered, with comprehensive guidance on safety.
Power Supplies Explained, second edition, sets out to demystify power supplies and encourage readers to experiment with their own designs. It is highly recommended as both a practical reference and a fascinating guide to one of the most important—and intriguing—areas of modern electronics.
