urgent : regarding ferrite transformer

[m.mokhtar]

Hi,
I have a big amount of ferrite transformers I have no data for them , I want to usethem for 4 KHZ sine wave and inpu voltage 10 V , output voltage 130v , and output power 13 W .
Can any one help me , I can design it if I know the data for the ferrite core ; but I don t , is there some way to estimate the nomber of turns on both the primary and the secondary.
many thanks,
M.Mokhtar

hi,
here i have to attached ur request

you can check how many turns you need for x frequency so that you do not saturate the ferrite.

Check the link below:

So when you now this, it is easy to calculate.

If you need more help, just post your question.
