Ignition coil as Hvdc transformer

Click For Summary
SUMMARY

A large-scale ignition coil can effectively function as a high-voltage direct current (HVDC) transformer when utilized in a switching power supply or switching converter configuration. The discussion highlights the existence of numerous circuits designed for driving ignition coils, particularly for applications like plasma bulbs and Jacob's ladders. However, many of these circuits are poorly designed and may only produce flames, emphasizing the need for caution. Reliable and safe HVDC power supply construction requires a solid understanding of the underlying circuits and theory.

PREREQUISITES
  • Understanding of switching power supply principles

Can a large scale ignition coil drive type circuit can be used for stepping up the dc voltage
 
Engineering news on Phys.org
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.
