Ignition coil as Hvdc transformer

    Can a large scale ignition coil drive type circuit can be used for stepping up the dc voltage

    There are lots of sites with circuits to drive ignition coils for plasma bulbs or jacobs ladders. I wouldn't try any of them, especially those that use a dimmer connected to the mains or a camera flash. I was surprised how crappy most of the circuits are. Really --- most of what is being said and the crappy circuits I saw would only produce flames.

    This is the only site I found with solid information and theory of operation. As you can see, beyond a simple mechanical switch method, it is not simple to safely and reliably build a HVDC power supply. If you don't understand the circuits and the theory, don't try it.
