Alright, starting from the beginning - a book, magazine, article, web site, ANYTHING to show the principles and objectives of high performance power supplies design would be greatly appreciated. So if anyone is the owner of an excellent reference or knows of a great place to start, please let me know!Thanks again!

Since you didn't specify a range of voltages and currents, or specific
applications, the best design I can recommend comes from the 1995 issues of The Audio Amateur, by Walter Jung. It is a series voltage
regulator design built around a low-noise AD797 opamp and operates
up to a maximum of about plus and minus 24 volts.A circuit board and a copy of the articles, which go into considerable
analysis of various three-terminal regulators and other discrete designs, are available from Old Colony Sound Lab for $25.(http://www.audioXpress.com)
I've built several of these and they seem to work very well; they're
quieter than any three-terminal regulator I've tested, and their
output impedance is exceptionally low over a very wide bandwidth
when carefully constructed according to the articles. I'm using one in my Hafler SE100 all-JFET preamp.I'd also recommend checking out Linear Technology's web site for
their application notes on their three-terminal regulators, which will
provide most of the details you need to built a good regulator. I
much prefer to build those with a 100uf or so cap on the ADJ pin to
ground, for lower noise and ripple.Anyone have suggestions for shunt-regulator designs? I've never worked with these.
This is good advice re. manufacturers' application notes. Ranging from simple hints to complete applications (DACs from BB etc.), they are an excellent source of information directly from the source. Basic rule when (re)designing a circuit, read the application notes for every semi you're planning to install, and when you've finished, read 'em again!
Damon,Shunt regulators generally only regulate at about 1% whereas a basic series regulates to .5% or better, so the series is usualy the prefered method.z

Ok, I'm looking to improve the power supply in a samsung 709 dvd player. I had posted a few weeks ago about wanting to learn about basically all electronic components and their functionality in a CD player. Now I have decided to simply start on the power supply. Spend a great deal of time on that, once satisfied with my knowledge, to build one and replace the current one in the Samsung. Then from there I will move on to the digital or analog section, and do the same. I'm very interested in a great piece of equipment after the mods, but more interested in the knowledge I'll gain from the research and construction.Thanks!

The best intro to the building blocks of electronics is still:The Art Of Electronics
by Horowitz and Hill
Cambridge Press
This is now 10 years since the 2nd edition. Will there ever be a 3rd?
I suspect the task is now too great, as electronics is an ever expanding subject. Still this book led to many new authors writing in the chatty "real-life" style rather than the "maths is good for you"
style of the martians who wrote engineering books prior to it. Still the best IMHO
Does this book give a large focus to power supply design? I already own and am working on reading through "Microelectronic Circuits" by Sedra and Smith. I don't need general background like that of op amps(something I've spent a fair amount of time on), but would like to focus on power supply design for now. Gradually working my way through.Thanks,
Andy
It has chapters on power supplies and precision design, as well as all the usual foundations [and some exotic topics]. The digital info may be dated now. Sedra and Smith is liked by lecturers and covers similair ground at about the same level. The focus in Art of E was more about real design info [like you get on application notes] rather than just a first principles coursebook. I am not familiar with modern textbooks and I guess they may all have borrowed this style nowadays. I think either book would take you to the level of designing a PSU to a required spec. The remaining "magic art" info [surely not much for power supplies??] would be from industry designers in application notes or articles for example by B. Pease, D. Self, B. Duncan, B. Gilbert etc...
Some of these have a very dubious view of audio debate by non-engineering experts.
