His new numbers, attained via confirmation of lamp output with a light meter, are a more reasonable 92% efficiency or so, which is still pretty good, but not OU.

I really would lke to see some scope shots of the involved waveforms from this.

Many thanks.

Regards, Stefan.

High Frequency Domestic  Induction Cooker - circuit

http://inpressco.com/wp-content/uploads/2012/02/Paper5126-132.pdf

Good paper, thanks for finding it. The envelope-modulated sinusoidal waveforms shown in the paper are similar to those shown by Tagor above. From the paper, I think I am understanding that the envelope modulation controls the depth of penetration of the heating effect into the pan, while the basic, higher frequency oscillation is what is transferring the power.

Here are some variants on a simple Zero-Voltage Switching self-resonating oscillator which can be used as a wireless power transmitter, a flyback driver, or an induction heater, depending on the frequency and the geometry of the output coil, and the power supply.
I use variants of this basic circuit for my wireless power systems and my flyback Jacob's Ladder.
By lowering the frequency by making the output coil bigger, say 30+30 turns, Litz wire, flat, and using a power supply and mosfets that will deliver more power to the coil, you can have your basic induction frying pan heater.
Lower the frequency with big capacitors and you can have the classic induction furnace, with a few loops of copper tubing for the output which wraps around your metal object to be heated. Again, mosfets and power supplies must be up to the task. Generally the mosfets stay pretty cool if the circuit is working properly.

It's the same basic circuit, though, in each case.

In the versions below, the cross-over diodes can be any robust, fast diode; the zeners can be 12 or even 15 v; the 1000uHy choke value can be varied quite a bit; the mosfets I use for ~800 kHz wireless power (single turn air-core output loop) are IRFZ44n and for lower-frequency flyback driver (5+5 primary on ferrite yoke)  IRFP260; for induction heating (larger spiral coil) IRFP460 on good heatsinks. The capacitors must be poly film type and over-rated for voltage; use high quality caps. Do not attempt to operate without the load, you will blow mosfets instantly.

With tight coupling, bifilar coils of Litz wire, and IGBTs or very low Rdss mosfets in the commercial induction heater circuit I would expect the power transfer efficiency to be quite good (but not greater than unity).

These circuits do not produce the envelope modulation of the commercial cookers, though.

A neat thing for Jean-Louis to try would be to put a second load coil and light bank on top of the first receiver coil.

Why not add another Bifilar Coil on top, so there are TWO of them.
 
It seems logical that some of the radiation is sneaking past the coil
in the picture, so why not capture it with a SECOND Coil?
 
Even if the second coil only got another 20%, it's better than nothing.

Or, maybe 1 receiver coil on both sides of the transmitter coil?  I dont know if one will take away from the other.

So Naudin did some measurements with a DSO and I must say at first sight things certainly do seem interesting. The scope reveals, as questioned by some, a non sinusoidal waveform meaning a scope/DSO is an unmissable asset if you want to argue about power output. Since he didn't share the test data and I wanted to know if the average power output he found of 1812W was indeed calculated correctly, I went and did a simple visual integral/mean calculation myself on the shown image he posted.
Basically I calculate the area under the power output graph in pixels and divided it by the length also in pixels, then this value is normalized using the height of the original graph. The mean value I obtained after this process was 1835W, this is very near to his value so we can safely assume he calculated it correctly.

Edit: I just noticed he indeed DID share the data. :D

@ all
I looked it up much earlier: D
it works
but we do not use the full potential of this design.
Displacement curent is wasted.
The new year will be exciting.

I updated the video test mentioned earlier:

with English subtitles (you may need to switch them on).

That video is quite interesting and perhaps even very important. It shows that the measured voltage has also a 50Hz component, due to the mains, when you "zoom out". If this is also present in Naudin's setup then it changes the data entirely and thus also the calculations.

@ Broli
 
Super nice job calculating that waveform area.  Thanks.

If someone came to you and said, "Look, I have a power supply that makes 1800 Watts ("RMS!")  at 24kHz, with a nearly sinusoidal output waveforms. Can you help me to convert this output to 50-60 Hz so I can use it to power my 1kW induction cooker?" How would you approach the problem? Could you do the conversion at better than 60 percent efficiency?

How about using the coil's output to feed a full-wave bridge of fast diodes, using the DC output of the bridge to charge up a big reservoir capacitor to the peak output voltage, then using an externally-clocked H-bridge of very low Rdss mosfets to make the 60 Hz AC output? Can you get better than sixty percent efficiency from an arrangement like this?

I would tell him to rectify and filter that signal first before we can talk about that ;).

Oh, you are fast.
