Lately some Russian hobby size induction heating videos have been coming up on my Youtube recommended list.  I don't understand the language, but I can get a pretty good idea of what is going on from almost all of them.
  Anyway, here's one where the guy simply couples the output from an induction HOB (British for "Hotplate Or Burner) to some copper coils and then parallels the output part of the coil structure to some capacitors.  So, as far as I can tell, without modifying the HOB in any way, he has a high frequency driver.  Maybe not great at power transfer, but I thought it was an interesting Hack:

Interesting :) After having taken a good whack at the cheap 2kW ikea stove ( http://kaizerpowerelectronics.dk/general-electronics/hacking-ikea-2kw-induction-hob/ ) I can also conclude that trying to change that beyond its 20-25kHz is sudden death for the circuit.

In one of that Russian guys other videos there is some details of the secondary circuit.

This simple induction tile fixture makes it easy to temper the steel tool. At the same time, the tile perceives this device as an ordinary dish. And works in its standard modes. For the manufacture you will need five meters of copper tube with a diameter of 8 mm, 18 capacitors of 0.33 UF at 630 volts and an incandescent bulb at 60 watts.
