    i want to make a transformer driver that will have adjustable frequincy output to test power and switching style transformers and posibly fly back transformers. i have some driver boards from old smps power supplyes i wanted to try for this but have no idea on how they work. and i beleve they need 110 ac to run i want to run them from 3-12 v dc some where in that range. i have tryed googling how they work with not mush luck. and testers are like a cople $100. i am just needing a schematic for it or know how to convert the old smps driver. i asume if i cant i can probly use at least the driver transistor. and i also got about 4 hot tranzistor from tvs and monitors if i need this.
    any ideas or a schematic will help lots thanks.
