Flyback Transformer Driver
July 17, 2011
I took a flyback transformer from a crt monitor and built the driver here - http://tacashi.tripod.com/elctrncs/555sstc/555sstc.htm
I am running the circuit at 19V with a power supply rated for 3A, but I cannot get the HV line to arc. I even hooked it up to a multimeter and found that I wasn't getting any voltage at all. I have tested the circuit, and it is fine. I have even tried winding my own primary coil around the core (used internal and my custom wound primary) , but I still can't get any power from the HV line.
Any reccomendations? I would like to stick with a simple 555 driver.
