Induction Heater

[Razor]

I'm looking into creating an induction heater. No specific purpose, just for the challenge of building one. This will obviously be a long term project. I'm requesting any links or advice you may have. So far I've found one really good link (http://www.richieburnett.co.uk/indheat.html). Check out the rest of the site too, it has lots of great information for electronics projects.

If you don't know what an induction heater is:
Wikipedia Explanation (http://en.wikipedia.org/wiki/Induction_heating) (not overly technical)
A Demonstration (http://www.youtube.com/watch?v=y_-Iv9FddOU)

that site looks good ^

erm yea as to the 'high' frequency AC I don't know what to recommend, perhaps a simple step up transformer would do the trick or a variac for moar controlled power output. As for the coil, copper wire springs to mind, probably using this kinda of formula you should be able to calculate what is best:

Good luck.

Looking over OP's primary link the author knows his stuff. I can't really add anything to it, except that the iron cores out of flyback transformers in TV's and CRT monitors are great inductors for high frequency circuits. I can't say that I particularly like his inverter driver, but it does work, so I can't knock it.

Hey There,

If you want to make a long-term project of it, of course you may, but you don't have to.

Google search for Neon John Induction Heater. There you will find complete plans, schematics, even ExpressPCB files. also parts lists and sources.

This is for a 1200 watt heater, which you can build in no time for next to nothing. all the stuff on his site is free. very impressive circuit too, if I may.

It's worth a look, anyway. Good Luck!:)
