    Hi all,
    I'm wondering if you can wire two seperate transformers with the same turn ratio together like the attachment. The primary sides are wired in series while the secondaries are wired in parallel. I'm sure this will work mathematically. What would happen if the impedance of the transformers were not exactly the same?

    don't worry abaout inpedance worry about phase

    Well ok, just in general what would happen if the voltages produced on the secondary coils weren't exact?

    Hello,

    It would work if you keep track of the start and ending of a coil.

    In the picture the Dots give each time the start of the coil.

    Would I still get 1V out if I didn't parrallel the secondaries and just left the other one open and tied my load to one? I know my power rating would be cut in half, but that's not an issue.

    Absolutely. This method was used frequently for multi-line-voltage equipmnet back in the dark ages (when I was a "yute") :)

    Absolutely, you can't get what you desired when not parralleling the secs coz two prims weren't magnetically well coupled

    Your question relates to identical transformers. i.e. the number of turns on both primaries and both secondaries are equal. It follows that their secondary voltages will be equal.
