If you're an avid electronics enthusiast, you've more than likely had to build some power supplies. The days of building simple linear supplies are over. If you need various voltages that are carefully controlled and/or just want to build efficient supplies, you need to build a switchmode power supply. This handbook will take you through the major topologies, explaining them all in detail, along with the necessary math to choose the proper components, and the theory of how it's done - and how to choose the proper topology in the first place. The book is well-written and stuffed full of very useful information. Power Factor Correction is also covered, with examples, chips, and theory to build PFC circuits, along with transformer design and theory as well. This book is a great book to buy with "Switchmode Power Supply Handbook", by Keith Billings. Keith's book presents additional information and transformer design mock-ups, along with additional ways to calculate and pick components. Used together, you have the information you need to build a working switching supply with a minimum of hassle. Of course, this assumes that you're already famaliar with electronics and magnetism, and have a good working knowledge of algebra and basic trig. These books are not meant for beginners by any means. I am one happy customer to have found such a good reference for an art that seems to only be known by a few anymore, and other reference materials do not even begin to go into the depth that this book does.
The only shortcoming is that Pulse Width Modulation power supply chips are not covered much, but this book cannot be expected to keep up with the latest PWM chips used in switchmode supplies. This problem is easily resolved by going to National Semiconductor's website and getting current datasheets on PWM chips for standalone, voltage-controlled or current-mode designs, of which they have many. Motorola also has reference materials available on PWM offerings that they carry. |
