The First TPU

[hartiberlin]

Hi EM,
I would be astouned,
if you would get 11.5 Volts,
but the lower voltage is maybe just a change in the working point current
and as the capacitors are a voltage divider there might be just lower voltage on them
in the new working point,
or am I wrong ?

I did more tests today.

I connected the scope across the inductor, and sadly there was no DC voltage.   So, I believe the DC voltage might be occurring due to circuit loading or phase changes or something like that.   (Stefan, the drop is about 1 volt and a half, not 11 volts, that would be great  if possible. I think you are right, it's the voltage divider effect now that I think about it.)

The orientation of the magnetic field seems to also work at 90 degrees to what I showed on the circuit diagram above.

Now,  looks at the attached pictures. 

You can see the heterodyne phenomena taking place.

So once again, the heterodyne takes place when I bring the magnet close to the ferrite toroid (it's small 1 cm diameter)

In the figure above, the magnet is laying down on the carpet farther then where this takes place  (I froze the waveform on the screen so I can take a picture)

So we seem to have a beat frequency of about  1/15us = 67 kHz

And the main frequency of about 1/3us = 333 kHz

So does this mean we have two signals that interfere with each other,  let's say   333 kHz  and  266 kHz  ?

I wonder why these signals appear.   Right before this occurs I just have the 330 kHz signal, and poof it breaks out in this new mode of oscillation as I move the magnet just a tad bit closer.  This could be modes of resonance where the inductor maybe starts to resonate with the other capacitors on the board.  Who knows, it's quite interesting anyway.  I should say that it's common knowledge that saturated cores produce distortion and harmonics, but I'm not seeing harmonics here, something else is occurring which might very well be resonant mode locking.

I'm anxious to see if Jack Durbin's original video might be showing this first TPU device.

This device and what Steven Mark says about it, is related to an antenna capturing the magnetic wavesÃ,  by being tunedÃ,  (the magnetic field of the earth "which inherent frequency" like he says in the video)

Now, Jack said he was hired to work on wireless power transmission.Ã,   I find this interesting.
