looks good, can't say I can find anything wrong with schematic

you can probably get away with one less primary wire and use one or two more for secondary, where the current is higher

Hey Luka, do you know of a schematic with the same voltage output and current but with 110 input voltage? Or how this one could be modified to use 110?

If possible, try to analyze this circuit, to beginners and those who are wanting to learn your skills and experiences . If you guys olso have time,please do this.

All you would need to change is make link in the right place to make voltage doubler on input and that's it... just like PC supply have switch, same thing, same place, one position is for 110 other (no link) is for 230

Hi.We have 3c85 material ,etd54 and frequency is 28khz.
Can we estimate how much power max can i get from this design and what should be the primary turn number and lead diameter?Thank you

I forgot to say.Duty cycle is 45%

I think you should give a go with this program

SMPS transformer design tool (ver.4000)
