Editorial Reviews

Book Description
Using this book as a guide, Pressman promises, even a novice can immediately design a complete switching power supply circuit. No other book has such complete instruction in one volume. Using a tutorial, how-to approach, Pressman covers every aspect of this new technology, including circuit and transformer design, using higher switching frequencies, new topologies, and integrated PWM chips. For this latest edition, Pressman has added in-depth discussion of power factor correction, high-frequency ballasts for fluorescent lamps, and low-input voltage power supplies for laptop computers.

From the Back Cover
A practical guide to state-of-the-art power supply design
Nowhere else can you find, in one book, all the information you need to design a switching power supply. And no other book on the subject is as practical, yet mathematically sufficient, without being unnecessarily academic. Using a tutorial, how-to-do-it approach, Pressman first explains basic principles and why thigs are done as they are. With a knowledge of basic principles, the engineer can easily cope with new design requirements and evaluate alternative design decisions. The topics covered represent all those areas where a design decision has to be made in commencing a new design. These include: Topology Descriptions -- A quantitative description of the roughly 15 commonly used topologies. Maximum current and voltage stress on power transistors for specified input voltage-output powers are described. The discussion permits selection of an optimum topology for the specified input-output voltages, output powers, and the selection of the power transistors; High-Frequency Magnetics Fundamentals--Ferrite core hysteresis, coil skin effect, and proximity effect losses; Transformer Design--Derivation of equation for transformer core selection for available output power as a function of frequency, flux density, iron and bobbin area, and topology; novel charts derived from the equations, permitting core selection at a glance; core, coil, total transformer loss, and temperature rise calculations; transformer design examples in major topologies; DC Current Biased Inductor Design -- Design of inductors carrying DC bias currents using ferrite, MPP, Koolmu, and powered iron cores; Magnetic Amplifier, Snubber Designs, and Resonant Converters; Feedbak Look Stabilization; Critical Polaroid Waveforms in Major Topologies.

This second edition adds chapters on the current hottest topics in the field; power factor corrections, high-frequency ballsts for flourescent lamps, and low-input voltage power supplies for laptop computers.

I wonder if I am alone in being a bit concerned about the somewhat decreasing number of books on fundamental engineering topics. It's starting to be a bit of a worry- I have tried to dig into, for instance, the subject of IGBFET physics and actually came up with a rather good book. But generally, this is getting to be hard work and good luck.

Take this book, for instance. If this book suddenly went out of print, loads, and I am serious here, MANY of us would be in dead trouble, because there are just not so many books in this league. By the way, go and buy the book by Keith Billings as well. These two dovetail together beautifully. I think these two gentlemen were good friends and decided to corner the market with two definitive texts. Sneaky! Thanks though guys.

This book is a very fresh and approachable encyclopedia of the whole area, just about. The chapters are all very comprehensive and go right the way through the beginnings of the subject to very detailed focus on many diverse issues.

When I use the word "encyclopedia", don't be put off. The real temptation is to read it like a novel, and why not, it's totally addictive, well written, and you go away really feeling very enlightened.

Great points in favour are the huge chapters on bridge, half bridge, flyback, feedfoward, current mode, and current fed architectures. These are pretty exhaustive and tell you the whole bit - including reasons to choose them and reasons NOT to choose them.

The chapter about feedback loops and stability could have been written to put you off, but even this subject is very accessible here.

Mr Pressman passed away a while ago sadly, so no more new editions of this book, I'm afraid. It is inevitable that there are some subjects not covered. Among these, planar transformers is ...possibly... a bit vexing, as this is quite hard to dig up (try joining the IEEE, that tends to fix things). Another subject is MOSFET switching losses and the peculiarities of schottky rectifiers... But that's OK, since a lot of this is covered by the book by Vtezslav Benda and the applications notes by ST and International Rectifier on the web very well.

Harder to spot are books covering the new classes of very high frequency convertors, and the engineering issues (esp. EMI)covering them.

None of these are detriments to the book - which is excellent.

The book tends to concentrate on the theory of the general classes of circuit, while Keith Billings book concentrates on the various problems arising in all and every kind of topology.

Wheras this book will tell you about the voltage waveforms in half bridge convertors in great detail, Keith Billings book will tell you about low voltage protection, soft start, and rectification (thought that was trivial? Wrong....) issues. These are usually independent of which configuration is in play.

I should say that you should go and read more of this stuff. The Benda book is good, but so are half a dozen books which are out of or going out of print. Scramble while you can.

This appears to be a subject area in which maths becomes suddenly important, and gives the lie to the general belief that engineers don't need it - a bit like filter theory, deeper than you think.

Anyway, enjoy the swim and don't be afraid of drowning!
