Selfrunning cold electricity circuit from Dr.Stiffler

[k4zep]

Dr. Stiffler has just updated his website with
a higher power incand. bulb output experiment.

Have a look at his new scopeshots.

Reminds me a lot at the scopeshots that Roberto und Otto
got  in their TPU research...

Good evening Stefan, Dr. Stiffler and all,

Well messing around this evening some more and some interesting results but first, I don't see the schematic of the High Power Unit on the web page, it is pretty straightforward but seems to be missing.

Second, I show a schematic of where I am right now.  Notice CX (C2) this provides positive regenerative feedback and when the circuit is tuned dead on, significant more output in my unit.  I only offer it for reference.  You can see that with C-1 now, I can peak the L/C circuit to match the L2/L3/Cx circuit.  This is just a start to see if my idea worked.......CX is .047uf mylar in my case.  I have no idea if that is optimal.  Just something to think about while I wait for good coils to come in.

Oh, Stefan, I heartly recomment you get a good Sig generator of at least 20 Mhz and probably from what I see on the scope shots from Dr. S, 50 Mhz!.  Your circuit is great but you need a GOOD TUNABLE device it sure makes life easier!

Hi Ben,
interesting feedback.

Will try it tommorow.
I have to go earlier to bed now in the next days, so I just don?t live at nights only...

What about this function generator ?

You can buy it as a kit for a built kit ready to go.

http://www.elv.de/output/controller.aspx?cid=74&detail=10&detail2=6325

But it only goes to 20 Mhz.

Maybe Ron can tell us, what the highest frequency is, that is required ?

But I will also have a look at ebay.

Regards, Stefan.

Hi Stefan,

I know what you mean about sleep.  It is 1:09 A.M.  I have spent the last 7 hours humped over a scope and trying to better understand this circuit.  It would be nice if Dr. Stiffler could give us a one paragraph take on the basic theory of how it works.  It appears that it has to be a potential fed circuit and not a current fed circuit.  Everything seems to depend on it having the least switching current @ the highest potential into the open ended device whereupon output potential is converted into current via the AV plug. The LC circuit basically takes the low impedance of the sig. gen and converts it to HV RF to drive the BF coil hence the AV plug.

Generator looks good but if you can get a HP, Tecktronic,  B&K, or any good RF sig generator that has a good power supply and well shielded would be better in the long run.

If you put any great amount of resistance into the input circuit to measure current reference to sig. generator ground, it drops out of OU.  Anything higher than a 1 ohm or so in the input side so you can measure voltage on both side referenced to ground will give you unbelievable high pulse current across the resistor and the device is under unity if measurements are to be believed but I suspect that procedure is faulted.  If you keep the impedance/resistance low in the input circuit, drive with pure potential switching back and forth power flows via the longitudinal potential only waves.  I'm up to about .166 Watt output now, very bright 10 LEDs with virtually no input current (I think) trying to find/buy a RF probe to get a more accurate series of voltages across the circuit.....Hummmmm just had another idea..Going to wait till tomorrow................Man I'm pooped, tired...... going to sleep on it......I'm gone to bed.

Raising the input resistance is one of the best ways to measure input characteristics in dificult to measure circuits... you keep raising the input resistance untill the output drops to 50% -- this tells you the input impedance of the circuit.

If the circuit was running in a potential only drive mode then you could raise the input impedance a long way -- to say M ohms or at least 100's K ohms, before the output dropped to 50%. The fact that you cant raise the input impedance much indicates that the circuit really requires a significant current to drive it...  This makes sense as it appears to be a seris LC resonant circuit which will give high voltage rise but needs a very low impedance to drive it. You could think of it as a low to high impedance matching network -- this is a great way to generate high voltages from low voltage (current mostly) drive without a transformer. Voltage gains are only limited by the impedance ratio and the Q. Google "impedance matching network" for more information.

It would be nice if Dr. Stiffler could give us a one paragraph take on the basic theory of how it works.

I was wondering that myself. In fact, why doesn't Dr. Stiffler publish complete specs on how to construct the device, since he has said he wants to give it to the world.

It would save people from wasting time guessing about one thing and another trying to replicate the device.
