Where Can I Find a Simple Guide to Transformer Design?

[mfc5200]

Does anyone know of a good link to basic transformer design? I keep seeing the standard equations but they don't seem like much help. I can't seem to find any good guides for designing the most basic transformer

For example, I will see equations relating the ratio of turns to the ratio of voltages, but does that mean I can go from 1 turn to 2 turns instead of 100 turns to 200 turns? I don't think that is the case.

Again, a most basic guide would be good, one that assumes no losses, etc is fine.

Well, there's still going to be maths but the PDF (Part 3, chapter 14) gives you some good transformer design concepts.

Edit: After rereading your post, maybe this chapter is a bit complicated?

haha, yea I actually find those slides when google searching, but they seem a little too complicated for me (I'm a M.E.). I was hoping for some really basic design slides.

An analogy in fluid mechanics would be to assume no losses with the fluid being isentropic, you can start with that, and then later fine tune your solution to take into account viscous drag, etc etc.

So far the best I've found is this, with regard to basic design.

I think I might have figured out my problem is though. Perhaps I will post later as to what the problem is, and what I think the solution is and why.

Thanks for your help.

The wikipedia page on transformers is a reasonable intro:

http://en.wikipedia.org/wiki/Transformer

As for the number of turns, you need enough turns for the magnetizing inductance to present a reasonable impedance to the driving voltage source, and you don't want so many turns that the wire resistance or the leakage inductance or the winding capacitance become large and obnoxious.

Transformer design is an art as much as a science. Between keeping up with materials, processes, cost, and the fundamentals, you're better off finding a designer. I live in the Dallas area, and there's a thriving community of these guys. I suspect any land of invention will have some transformer houses.

You can refer "transformer design.." book.
By M.G.Say.its very nice book.
