it is not possible to distribute the pins. pins with the same voltage have different number of turns.Why so?

OK, I ran your design parameters in PI Expert, and got this design, which I believe is more like what you expected - please correct me if I'm wrong. You may be able to go into your current desgn file and fix the transformer construction by dictating floating windings in the stacking section of the design. I, for some reason, always got 2 floating 7.5V windings when I ran the design.

I'm a bit confused as to your intent with this design, as the output voltage is stated at 12V/2A at the beginning of your design file, but then later on, there are two other 7.5V outputs mentioned. Are there really 3 separate outputs needed, or just the two ?
