How To Build A Simple But Powerful Flyback Driver

Step 3: Schematics

The 5 turns of wire as the primary is not critical, you can add or remove windings for different performance.The voltage input to the driver may affect the number of turns required as well.

The "47-200 µH" inductor can be customized to the desired output of the flyback transformer. In general, if you want a higher voltage, the inductor should have an higher value, if you want more current, the inductor should have an lower value. Also, an inductor is a 'must' for the ZVS driver, without it, your ZVS driver may work poorly or not work at all.

Changing the value of the capacitor can also affect the performance depending on the flyback transformer, again, make sure you use good quality capacitor.

What were the specs on the inductor

[knoxarama]

how would this work for a tesla coil power source?

here is my little one i made: http://www.youtube.com/watch?v=LUEPpR8uKIY
its run off a pretty much dead 12v battery...

It should work pretty well.

somethings wrong, when i turned it on it made the high pitch sound like you said but none of the terminals gave me any results, i tested it with two different transformers and i believe the do work

its because it is a pulsing voltage and you meter wont read it unless you switch it to AC, even then it might not read it because it is too fast.

maybe the terminals are not close enough
or it cold be to close to ground
