... we have 220V mains @ 50Hz. i have 135 windings on primary so doing the relationship of 220V / 135 =1.629 Volts per turn....(relationship chosen because i can only get 5 secondary winding on.) so 5 turns on secondary should get me 8V..after rectification about 11volts.....but i only get out 1.2v output with TEN turns not 5....WHY IS THAT?

forth... power in equals power out - losses, i will ignore losses unless that is what's eating my volts. using the equations for impedance. my 30mH primary winding gives me 9.4 ohms.... my 6.42uF series capacitor is 495.81 Ohms adding to together i get 504.21 Ohms so power is 220V x amps, amps will be then 220v/504 = 0.430A equals to 96watts.... 96Watts at 12V = about 8amps output.

what am i missing, why is the relationship of winding not giving me the correct volts, is it power loss?... if i must get out 13.5v on 10 turns secondary with 135 turns primary, and i get 1.2V then its a power loss of 91%... how is that possible? or what am i missing here? why can i not get my 8V output with correct winding relationships?

IMO that turns/volt ratio is WAY too low, for EI mains transformers the typical ratio is 3.5-5 turns/volt, Toroidal start at about 1.5-3 turns/volt.
See the video I posted.
I have wound quite a few in my time back in the UK, and always found them to be the ratio posted above.!

 

AGAIN, MAX is correct in that usually there would be more turns so thatthere is always more than one turn per volt. I do not have a simple explanation for that truth, but it seems to always be true. I will do a search of some technical books and try to locate the reason.
Usually I buy transformers to meet the specifications of a project, for the reason that transformers are not as simple as other elements.
