Good switching power book

I have "Switching Power Supply Design" by Abraham I. Pressman (ISBN

If you want it, send your address to FreeBook.jocjo at xoxy dot net.

I have your book. Thanks for all your online contributions.

Cheers.

Nothing for switcher basics, but the Old Unitrode Magnetics seminars from TI are worth a read.

I believe a link to a pdf copy of Snelling's "Ferrites for Inductors and Transformers" was posted in this group recently. It's heavy going though.

"Transformers and Inductors for Power Electronics - Theory, Design and Applications" by Hurley & Wolfle is pretty good.

Personally, I think the publications provided by the various ferrite manufacturers are adequate.

Hah, I read about 1/2 of this for an online SMPS course I took (from Erikson..) a year or two ago.

Looking for something to read the other night, I pulled it off the shelf and started in on the Magnetics section. (Chap 13 onwards.) there is not that much lot about core losses.

hmm I was trying to get amazon to throw up the core loss page... Here's a pic.

Also quite old but worth reading is Keith Billings. Sanjaya Maniktala has a more recent book too but I just do not get on with it. Unitrode app notes and seminar material was good and is on the web.

For magnetics have a look at Colonel (his name not rank) McLyman, some available on the web or search old SED posts.

There's an old standard switcher cookbook by Marty Brown.

You can probably find the PDF floating about somewhere.

Can't remember if its a Motorola or TI publication, but both have released books on the subject.

someone else mentioned Unitrode - also a good place to look.

I found the Maniktala A to Z to be a good book to understand the relationship between different parameters and easy to comprehend

Colonel McLyman good for deep understanding of transformers

Snelling is comprehensive, but a pedagogic disaster. The Siemens/Infineon m agnetic application notes were a great deal more accessible, and pretty muc h responsible for getting me to where I needed to be in that area (which wa sn't actually the cutting edge).

Ralph Morrison's "Grounding and Shielding Techniques" is amazingly clear an well organised, but doesn't go deep enough into magnetics be be all that h elpful.

Maniktala has some good things to say, but a fair few of them seem to be about Maniktala. ;)

Hi, Tim -

I hope you got my email giving you the UPS tracking number. If not, please contact me again. I make lots of mistakes these days.

BTW, I hope ground delivery is okay.

Cheers, John

Actually, the Siemens (now EPCOS for ferrites- I got that wrong) application notes are what you really want. The data book is good, as a data book, but the applications notes were remarkably good.

The application notes are on pages 142-169 of the EPCOS "data" book.

The "application notes" such as they are, don't include the transformer equ ation

V1 = L1. dI1/dt + M. DI2/dt

V2 = M. dI1/dt + L2. dI2/dt

where L1 and L2 are the inductances of the first and second coils on the tr ansformer and M is the mutual inductance which has to be less than the squa re root of L1.L2 (and frequently more than 99% of that value).

The original Siemens application notes did - back around 1979 when I first read them. The application notes in your version of the data book have been pruned back to Snelling-like snippets - great if you know precisely what y ou are doing, but unhelpful if you don't.

A very interesting book with lots of sample and working SPICE design examples is the one by Basso, from I think STMicroelectronics. Very useful hands-on learning experience.
