    That's a serious undertaking, which is why I don't think people are responding right away.

    I would start here,

    You're going to need a good sized e-core or toroid for 1KW. You must be extremely concerned about your magnet wire quality and insulation, otherwise your circuit will arc and fail prematurely. You should consider litz wire for lower copper losses.

    I would go to the library and take out a book on the subject, I have seen many in my university's library that detail construction of switching transformers. I cannot remember how to calculate the appropriate turns, but I know the information is readily available.

    1Kw@50Khz transformer is not too big. You can compare that with a commercial PSU of the PC. Commercial PC/PSU can deliver 400watts with a 42x 35 mm ferrit EI core. It is about 1/6 turn per volt. How about the wave form? This would affect the computation.
