Kapanadze Cousin - DALLY FREE ENERGY

Nick this is an easier circuit to lay out, mine is built like this with no problems.
I used irfp460's

[Dave45]

I built one on proto board but smoked it so the next one I breadboarded

You guys should take the time and build consumption meters, really helps.

  Although I've placed this link below before, more information is being added to it as time passes.
  http://www.rmcybernetics.com/projects/DIY_Devices/diy-induction-heater.htm

  rmcybernetics.com is also selling ready made high powered induction heater circuits, along with adjustable controls. Might be the way to go... these should be able to handle what we are trying to do with them.
Although Geo does not think that commercially made induction circuit will do. I don't agree, as these can provide 180 amp output with frequency and duty cycle controls.

  Guys, thanks for the suggestion. I will try to connect my car battery charger, (12v. 10 amps) to my Mazilli/yoke circuit, and will report back. It may be that my batteries just won't cut it any longer.
  But, what I'd really like to see, is someone running a similar induction circuit connected to the Tv yoke, as I have, and to let me know just how hot their fets get when drawing over 500 to 700 watt loads.
BTW: Magpwr, my heat-sinks do have holes, and fins on both sides, and I've placed two fans on them as well. They are not blocks of aluminum, only.

   As mentioned, I plan on changing my set up when the zeners arrive, or I'll have to try to obtain them elsewhere (not easy). I also plan to include the bigger heatsinks, fans, etz...
   As I'm only running tests on this circuit for a few seconds at a time now, so the fans are not needed, although I have used them several times previously, but to no avail, fets still getting way too hot.
   I suspect that Hoppy is right, and the old batteries are the problem here. Maybe the fets are not switching properly, etz...even though the battery voltage only drops by 1/2 volt or so, when running the circuit.
  This has been an ongoing problem for me from the day that I built this circuit, as well as my Joule Ringer circuit, which also has the same transistor heating problem, when running 60 watt plus incandescent bulbs.
