    we had this UPS that had its socket fused or something and i opened it . i found a battery that is charged, a big transformer that is in the ratio of 450:1 and a circuit board that takes the power from the battery... turns it into ac and into the transformer and to the computer....


    now.... can this transformer take that current and ... return it for the second time throught the process... (thus cycling nodes from the fist process and antinodes from the second process together).... producing a steady dc 240v output? or would it fry the whole thing?


    might sound stupid... but it would be awesome if you could use that in a jacob spiral ladder :O

    might be useful as a 12 to 120 or 220 inverter. Voltage higher than this would probably blow the insulation. do not quite understand your idea of returning it a second time, but do not think this would work. turns ratio seem almost too high to believe, how did you get it. a schematic, as always, would be useful.

    youre right .... its 45:1 ratio


    ill try to find a schemtic of the thing... but no luck yet
