I find this setup most interesting,infact my induction cook top is on it's way.
I have some thoughts about the setup,that im supprised JLN hasnt thought of himself.
It seems to me that things are reverse to what would work best-in the way of the coil arrangement.
Some testing would be needed,but i believe that a BPC produces a stronger magnetic field than a flat pancake coil for the same watt input of power.
Dose anyone here know how the induction cooker's are tuned(if they are)?
Do they tune the circuit so as it runs at the resonant frequency of the coil inside?
If so,will there be tuning pot's as such as we can retune the circuit if we install another coil?
The reason i think the setup is backward's is shown here in TK's video.
The induction cooker has a flat pancake coil(single wind),and nauden uses a BPC as the collector-should it not be the other way around?http://www.youtube.com/watch?v=mvb39SwTXBE
So my next few days will be testing a flat pancake coil,and a BPC of the same amount of wire-useing the same amount of watts to drive them.
It would seem that TK is pumping the same amount of energy into each coil.
This can mean only one of 3 thing's
1-the BPC is indeed a better transmitter for the same amount of power.
2-The single wound pancake coil is a much better reciever than a BPC.
3-Or it maybe a combination of both.
So lets see if a BPC has a much higher magnetic field strength than a flat pancake coil-for the same amount of watts.
