Hello. I have a question about driving an Ignition coil from a petrol powered car, can i use my ZVS driver to somehow run it ?
I can try to build a transformer out of a flyback core that i got, on 1 side 5+5 windings, and on the other side, how much windings give you 15 Volts ( Mine is rated for 15 ). It will be driven at WERY high frequencies tho.No, you can't use it.
The primary of a car ignition coil is meant for 12V only - sending the output of the ZVS into it will just cause flash-over in the winding and ruin it.
I tried to run it with the ZVS, i dont know how much Amps are going into the Coil, but all i know is that theres going in more than 100V. Im saying more than 100, cause i measured the voltage of the secondary coil on the Flyback core a long time ago, and i dont really remember what it exactly was, but i remember it was over 100V. Ive made the secondary coil on the flyback core from a thin wire, which i dont know the gauge of, but its 1/4 the size of a toothpick ( with its insulation on ). The switching frequency has to be REALLY high, cause when i allow it to arc over, the arc is wery high pitched. I dont have a REAL purpose for it, its only a high voltage Power Supply.Any form of oscillator attached to the primary of a car ignition coil should produce an output on the high(er) voltage side.
The voltage put 'out' will be proportional to the voltage put 'in' multiplied by the turns-ratio of the transformer (coil).
You are only limited by the breakdown voltage of the wires used to wind the coils and the saturation level of the coil core (magnetic flux density).
Car ignition coils are (I believe) iron cored so their efficiency will fall off as the switching frequency increases due to aforementioned core losses.
If you have a particular purpose in mind then please let us know and we can advise more accurately on how you might resolve any difficulties.
