    hello
    may some one help me for how to design a high frequency transformer(ferrite core)
    what is the parameter for design a HFT.
    how to define a core material, structure type(like EE, EI, O, CC,Etc.), core size, air gap between the core, and bobbin size
    how to find the no. of primary and secondary winding turn and wire gauge


    if any one of have the formula's about it
    please share ......


    thank you

    hello
    why we use polyester insulation tape between primary and secondary coil and above the ferrite core
    and how many turn use on it

    tape is used for insulation between layers - usually for safety reasons. It can also have big impacts on stability due to changes in parasitic capacitance.

    I recently found this app note helpful in designing my own flyback. I hand-wound my own EE transformer - and to my surprise it worked.

    sir
    how to calculate wire diameter for high frequency transformer and ferrite core inductor?

    and how to define ferrite core inductor ?
