Full bridge power supply Transformer design

[meysaminter]

Hi ,
I want to design a full bridge powe supply transformer . I don't have any resorces or application notes aboat designing . can anybody help me with this?

do you mean a switcher?

switching power supply.

Not a trivial project, I used to do it for a living. You will need to define the power design (input voltage, output voltage/power, converter frequency, core material to be used, physical parameters of transformer). Doing the physical layout of the windings may not be easy, it depends on the secondary current needed. Sometimes they use double or 4X parallel windings, sometimes foil. All depends on the design.

i have done it as well... as usual, a vague question... vague because the questioner is in WAY over his head...mind you flybacks are FAR worse!

While a hand wound switcher is likely to be inoperative much past audio frequencies, at least there is no precision gapping involved!
