thanks brother for your help it is very useful information for me but i already have bought 3 old transformers and waisted almost 30 meters of wire. here we already have 220 voltage so i think i don't to make two sources.But as i was trying to resolve it I gave both primary coils 220, 220 volts from different sources and centre tap the secondary coils and it actually worked, but soon after 10 seconds secondary coils were smoked, i used insulated 8 gauge stranded copper wire. Then i did same with three transformers together and power was enormous but they could only survive 15 max.
I made two transformers 1 with 28 turns other with 20 turms then center tap both of them, have check series several times, still i can only get 17.89 volts, can any one help?
I made these transformer with 1 having 25 turns and other having 20 turns but i can only get 17.68 volts max, i had check series and all connections but still unable to get 38 or above volts, can any one help?
