A power supply is often taken for granted by radio amateurs, as for many it is simply the box, that at the flick of a switch, provides stable DC voltage. A modern power supply is much more though, combining theory that dates back to the nineteenth century incorporating the latest techniques in digital control, with a wealth of electronics practice in between. Power Supplies Explained sets out to do exactly this - explain in understandable terms what that little box is doing, right through to designing your own custom-built power supply.
Some believe there is a little magic in power supply design. Beginners may be especially wary of the challenging mixture of digital, analog, magnetics and control loops, with cooling, EMC and safety to contend with as well. While many books deal with the theory in depth, they often give little guidance on the practical aspects of achieving working designs. Power Supplies Explained is different. This book describes how circuits are chosen for the application and how circuits are designed including their inductors and transformers. Calculations are outlined in a simple way so that the reader can use them as a basis for their own designs.
Readers will find chapters that include descriptions of 'linear' supplies and a wide range of 'switched-mode' types from simple buck converters to the latest off-line high-efficiency types. Practical examples are based around typical radio amateur requirements and in many cases are versions of commercial products that the author has successfully designed. There are also chapters on magnetics theory, control loops, EMC, practical construction techniques, test equipment and much more. High voltage power supplies are included with comprehensive guidance on safety.
