Transformer Bobbin Fit Calculation

Aneesh TS
Expert 1735 points

Hi TI Experts,

I am working on the Phase shifted Full bridge converter. I am trying to Optimize my Transformer Design. But always facing an issue that the designed number of turns and gauge are not exactly fitting the bobbin. i wanted to try different combinations like primary litz wire and secondary copper foil, Primary  normal AWG wire and secondary litz wire , Both primary and secondary as Normal AWG wire etc...

So can anybody suggest a good application note or Excel design files from TI for Bobbin fit checking.

Regards

Aneesh

    Hello Aneesh,

    There are multiple books you may be able to find books on how to design a transformer in switching mode power supplies. There are also many articles. You find these tricks over there. There is no shortcut to handle the tricks with a few points. So please just go ahead to study a book as well as other published articles. 

    Unfortunately, we do not have any application notes in suggesting transformer designs.

    Regards,
