Practical Design of Power Supplies
This book is written for a variety of people involved in one way or another with power supplies and power systems. The Primary audience consists of practicing power supply designers, people who have been in the field between 2 and 20 years for them, practical design of power supplies is just that, a compendium of important knowledge needed on a daily basis. Too often, practicing engineers spend their daysrushing about putting out fires (sometimes literally), and don’t have the time to dig through abscure manuals and references to obtain the information that would make life easier. For them, this book sets out exactly what they need to know to make a good power supply, with very detailed examples making it almost easy to do.rnPractical design of power supplies should also benefit skilled technicians in the field, those who have observed that doing this fixes that, but without knowing just why. The book’s examples all come from the field of low to medium power supplies (say 1 W to 10 kW), since that is where my experience lies. This book is targeted at designers of power supplies in the low to medium power range roughly defined as 0W to 10 kW. (Chapter 2 on topology talks about the various types). There is an excellent reason for having many different kinds, rather than having all power supplies be mere variations of parameter values on a single type. This reason is twofold, the wide variety of loads converters are expected to provide power to. Unless you have spent many years designing converters, you probably don’t realize how truly divers these two groupas are this is one of the things that makes power supply engineering far more challenging than, say, digital design. To start off this book, then, examples of sources and loads, both common and less so, are presented in some detail, to give you a feel for the sorts of thing you may encounter. The samples here are of course not exhaustive, but rather represent some of the (occasionally not so nice) experiences of the author in the power range under consideration, you can start your own collection. Don’t take these discussion to be comprehensive, as some of the sources and loads have a large literature attached to them, rather, this material is intended to give the flavor of the sorts of environment in which power supplies often need to operate.
