Hi, everybody. I will appreciate any help on how I would learn how to make transformer all by myself. Please I need this, because I can't do without it. Thank you.
That's a bit harsh, we all know that winding a transformer is easy, but getting the core and the correct number of turns on the primary right for the power level and frequency does require some degree of skill and experiance.
If you have ei trafo do this:
measure the package quadrature and that is S.
number of turns for one volt is 45/S
so if you have 10cm^2 - 45/10 * 220 for primar coil its 990 turns.
for secundary coil you multiply with voltage you want.
Power of trafo is P=S^2
Nominal power is P*0.7
Current is I=P/U
Wire diameter d = sqr(I/2)
