Yes, I've read your possible explanation. But my question was, if you can confirm your theory when you disconnect the mosfets from the TPU. Will there in this case also be a soustaining oscillation, without the electronic components (mosfets) connected to the TPU.

Hope I could explain it better to you.

Kind regards.

Thinking about this I see a possible explanation:
may be that the mosfets, even if without any input, do capture from the surroundings some electrical fields or more simply, as the their Drains leads are connected to the coils them just feed back some signal  (via internal stray capacitance and/or Miller effect) directly to their own Gates...so establishing a feedback path...that in turn does operate the Mosfets themselves...well is just a theory. Actually the current drain, with the same voltage setting on PS, in this operational mode is much less (than when feeding the 3 freqs in).

Hello all,

@Freezer

Im a master of NOT understanding what Im doing!!

I learned a lot about coils but I know that I have to learn, learn..  much more.

Yea, always more information to learn, I just think you guys have made very good progress with what you've had to work with, and perhaps this forum could change the way people think about new power sources.

Hi ronotte and otto,

It sounds like the oscillations are still present after the function generator is disconnected because the MOSFETs are still connected and the Gate is driven by stray fields.Ã,  Ã,  It's a very plausable explanation and can be checked very easily by disconecting the MOSFETS as wellÃ,  (after first disconnecting the generator)

Guys,Ã,  Ã, here's a circuit that will resonate pretty much anything you can throw at it.Ã,  Ã, 

It uses the concept of NEGATIVE RESISTANCE.Ã,  Ã,  (a bit more complicated then simple Gunn or Tunnel diode circuits but easily configurable and more versatile)

You can just hook up your TPU to it and if it has a resonat mode it will pump it and start resonating.

The beauty of these Negative Oscillators is that they eliminate the need for explicit FEEDBACK to accomplish oscillation and all you have is two wires coming out, that represent the terminals of a NEGATIVE resistor.Ã,   Then just hook up your resonant tank circuit to these wires and it will start to oscillate.Ã,   The theory says that due to the ever present small resistance in coils and capacitors, the power will be dissipated and any oscillations will stop.Ã,  However, hooking up a negative resistance in SERIES with the tank circuit, will cancel out the small positive resistance and allow the circuit to actually build up in oscillations.Ã,  The power of course comes from the circuit power supply.

Disclaimer:Ã,  Ã, Just in case you think I'm realy smart, this is not my invention, there are a few different circuits out there for accomplishing this same thing, and of course Gunn diodes etc..

Enjoy, and let me know how your TPU works with it.
