Hi

I was wondering if you could use a ignition coil driver and replace where the primary coil output would go to a separate coil which i can use as the induction heater coil. I have heard of people doing this, but is there a specific circuit you have to use in order for this to work?

For example can i use the circuit below?

Help would be most appreciated

Thanks

It's not going to work. Look up some schematics and theory about induction heathers.

Look at this: Link2 My iggy coil driver you have found isn't suitable, but I imagine any old 555 flyback driver running at around 200kHz would work.

Thanks for the reply's. Just wondering about the modified flyback drivers. Ive built a couple in my past and doesn't i usually operate at about 24khz or thereabouts. What kind of modifications would i need to make it oscillate at that high frequency?

Thanks
