    Greetings,

    I'm having a little trouble developing a power supply to deliver 14 vac
    @ 10 amps. I modified a MOT to deliver 14 volts but, the primary (5
    amps) and secondary (41 amp) amperages are so high, I had to put a large
    Iron cored inductor in series with the sec. to reduce the 41 amps down
    to 10. The power supply dwarfs the original design perimeter. I need to
    design a tranny to deliver what I need in a smaller package. What I need
    to determine is the primary to secondary turns and core size to deliver
    14 vac @ 10 amps.

    I have formulas for determining/modifying the volt amps in an existing
    design and, I understand these. What I don't know is how to target a
    specific set of values and how the core is used to achieve them. If you
    know of a source of information, please direct me.

    I realize I could find and purchase a supply to fit this need but, what
    would I learn?

    Randy
