Confirmation of OU devices and claims

[gyulasun]

Well, there was no 100 uF cap and 1 kHz frequency written in benfr's post.
Well, thats strange as I can go straight to it with the pointer I gave you on my machine!

AG, I simply do not get what you mean in your 2nd sentence? What pointer did you give ?

That only works on caps and resistance if you try it with caps and inductance you won't get the same result and I can't find any equation for such a setup.

I just checked the 90 degree phase shift Itsu measured, it is the attachment rick LC.png here:
https://overunity.com/17491/confirmation-of-ou-devices-and-claims/msg533810/#msg533810   

Now I see that in his practical setup (not the simulation) the 100 pF with the 163 uH coil cannot give 1.162 MHz resonant frequency but a 115 pF cap can give resonance. So his probe was in parallel with the 100 pF so it detuned a little the circuit from resonance and that is which may have caused the 88 degree phase shift between generator and capacitor voltage he checked. 

If you use this calculator what member benfr gave: https://www.translatorscafe.com/unit-converter/ja/calculator/series-rlc-impedance/   and enter 100 pF and 163 uH with 1162 kHz frequency, then you get nearly 74.4 degree phase angle, close to 88 degree what Itsu measured by scope (use R= 50 Ohm series resistance).
BUT his main goal with that measurement was first to show the Q times voltage amplification across the reactive components versus the generator voltage at resonance, this was correct even if exact fine tuning was not shown.  His second goal was to ask whether voltage amplification at resonance in a series LC circuit gives "overunity" ? 

Here is a good link for revising the calculation of series RLC circuits:

Yes, this thread is supposed to deal with confirmation of OU devices but so far this TX-RX setup failed in practice in this respect.

Anyway,   giving more courtesy towards all the members here is the polite way for communicating.

Itsu Hi Just a simple question, around page 20 you show a scope shot of a two trace align wave about 90 deg out of phase without digesting the whole thread how did you get that waveform > is it from a circuit or emulation and if a circuit have you a drawing I can view, please. many thanks, AG

Also before that, you show a square wave would that be created the same way?

again if you could please advise.

AG,

Gyula pointed (linked) in his above post to the specific post on page 20 you refer to.


All info on those 2 screenshots (1st one from the sim, 2th one from my real circuit/scope) are in that post.

Just picture the circuit drawn (see below), then for MY REAL CIRCUIT, picture the purple trace probe (CH3)
across V1 (FG and whole LRC), ground lead left (-), probe tip right (+).
I seem to have INVERTED the purple signal, so in real it should be flipped over (180°).

Then picture the blue trace probe (CH2) across C1 (series Cap), ground lead also left, probe tip right.


The reason for the voltages across the RLC (purple) and the C (blue) being 90° off is explained in a link i
presented a few post later to benfr (post # 295) where i wrote:

Please read up on series resonance circuits:
https://www.electronics-tutorials.ws/accircuits/series-resonance.html

Under "Impedance in a Series Resonance Circuit"

There it reads:

We recall from the previous tutorial about series RLC circuits that the voltage across a series combination
is the phasor sum of VR, VL and VC. Then if at resonance the two reactances are equal and cancelling, the
two voltages representing VL and VC must also be opposite and equal in value thereby cancelling each other
out because with pure components the phasor voltages are drawn at +90o and -90o respectively.

So (in resonance) compared to the "view" from across the whole RLC (purple), the signal across L and C are
resp. +90° and -90° (remember my purple trace is inverted) out of phase. 

Hope this clears it up.



Concerning this question:

Also before that, you show a square wave would that be created the same way?

I guess you mean my post #271 on page 19.

There i refer to Benfr his setup, see sim circuit (cap, coil, cap, coil, cap, coil in series) with parallel
across it a load (R1) and the FG (V1).

The square wave signal in both the SIM (green) and in my screenshot (blue and white) are from across the FG (V1).
The green (sim) and blue signals are when NOT in resonance (nice squares), the white one is what happens when
IN resonance (the resonance signal loads the FG in such a way that it forms these troughs.

Hi Itsu,
Thanks for the additional work you have assigned for this topic.
