I was woundering if one can better the performance of such a IH a bit by concentrating the flux as these guys did. Im thinking of something like a crt yoke on the outside of the work coil, provided that the resonant frequency is designed to be about 15KHz to suit the yoke.

What is that material they used to control the flux?

Hi guys
I'm afraid normal high permeability ferrite would get induction heated itself if applied like that. I suspect the material they use is something like those low-mu carbonyl iron materials, I might be wrong though.

Hi Beam tetrode may i ask a couple of questions? Is your royer setups final power output into the workpiece controlled by the input voltage? If the voltage was lowered to say 15v or even 5v for example would this just cease the induction heating process or would it just become very slow and less powerful? or would the circuit cease to function once the voltage dropped below a certain level? I say this as i am interested in the ability of your circuit to be able to melt metal but also to be throttled back to only heat to a core temp of around 100 degree centigrade for an experiment.
