Partnered Output Coils - Free Energy

[TinselKoala]

I've just tried my testbed with LED load. What a truly _nonlinear_ set of responses that gives! Far too many weirdnesses to list quickly, in both bucking and aiding modes. I'll have to shoot a video, probably tomorrow.  But remember that I'm using this op-amp based bipolar driver. Sometimes I think I'm seeing that the op-amp starts oscillating and that is causing some of the weirdness. It sure makes the LEDs glow, both polarities, when that happens.

@MileHigh:

Thank you very much for your explanations and for your advice. It really helps me to do better measurements. It is kind of you to take so much time for this.

The first thing I will do is the "reality check". I will check with the primary and each of the "partnered coils" (while the other "partnered coil" is left open). That should be interesting.

Then I have to go to higher power (1 or 2 Watt input) in order to better see what is going on. As you say, at the 40 mW level (at the input) I am in a difficult area because the transformer properties are dominant.

The 4.3 MHz situation is way beyond my level of expertise, I will leave it for the moment. The core is rated for up to 25 KHz, the 4.3 MHz are clearly not right for this core.

I measured the impedance of the windings with nothing else connected besides the LCR meter, even the "partnered coils" were not connected in series yet. The core was tightly in place (both halves secured with the steel clips):

primary: 23 mH to 25 mH depending on frequency (100 Hz, 1 kHz, 10 kHz)

secondary ("partnered coil") underneath the primary: ~ 240 mH (slight variations depending on frequency)

secondary ("partnered coil") on the side: ~220 mH (slight variations depending on frequency)

There might be a slight difference in the windings of the two "partnered coils", but the difference in impedance could be due to the fact that one has the primary wound over it?

One thinks, that measuring "input" and "output" is quickly and easily done. But as we see, it gets quite involved and needs a lot of knowledge and experience. No wonder, we never see good measurements. For most people it is beyond their capabilities (as one sees in my case, I barely manage) and a good scope is the bare minimum. A function generator might help but brings in more difficulties.


@MileHigh and TinselKoala:

The "GND connection issue" is very involved. At least I know now, that I have to be careful. I was not clearly aware of the problem with the "GND of the mains", the instrument housing and the "GND of the instrument probes or output".

The situation with my Function Generator and my Scope (I just checked again):

All probe and signal GNDs are connected together and with the "mains GND"! The housing is plastic (this is propably the reason why everything is referenced to "mains GND"). In other words, there is only one GND, and it is "mains GND" (which of course is in every mains socket in my house).

So, that means, "signal GND", "TIGGER GND" and "SYNC GND" of the Function generator are connected with "probe GNDs" and "TRIGGER GND" (even test 1 kHz GND) of the Scope via the "mains GND" (since both have to be plugged into a wall socked in order to have electricity). Well, battery operated instruments would be better. The function Generator could be insulated with a separation transformer (but this creates a "frequency issue", a transformer has a limited frequency range, surely not from 10 µHz to 20 MHz). One never stops to learn important things.

There is good news from my laboratory power supply: The Minus Pole of both DC outlets is not connected to "mains GND" and the two "Minus Poles" are also not connected to each other. But there is a "mains GND" socket at the front panel if one needs a connection to "mains GND". The housing is metal and is connected to "mains GND". The front panel with all the sockets, knobs and a little display  is plastic.


Thanks again for the discussion, I definitely learned a lot (and I hope that OU-inventors and OU-replicators take more care with their measurements in the future, they could also learn a lot in this thread).

Thanks Conrad for your comments.  I can't respond right now, but I am going to leverage your positive and appreciative comments to do some unpleasant "dirty work."

Synchro1 - this is a call out to you:

Contrast Conrad's comments with your junk comments about me from this thread:

<<<
You're completely full of shit about practically everything!
You're betraying yourself as condescending and obnoxious to everyone on the forum and it's entire membership trivializing us as insignificant. You're that perversely sadistic to practically everyone. You act as though no one can compare to you. All your comments are over padded with conceited drivel. That's why everyone hates your guts.
You're a nut case from hell!
>>>

I am really fed up by your constant harassment and abuse.  This has been taking place off and on for more than a year.

Everyone, please look at this short YouTube clip from Synchro1:  https://www.youtube.com/watch?v=YwMwhdJE_Vg

Listen to his voice, look at his hand, look at his body movements.  Between those three clues I make him to be a man between 45 and 55 years old.

So the question is:  Why is a 50-year-old grown man acting like a psycho on this forum?

It's time for you to stop.  I am issuing a public challenge to you:

I challenge you to post here and state that you will stop harassing and abusing me.

Just make the posting saying that you are going to stop, and that will be the end of it and we can all move on.

If you ignore this posting and continue to harass and abuse me then I will do the following:

1.  When you get abusive I will say nothing except for posting the two "Syncho1 shaming and humiliation links" in response.
2.  I am asking people of good will to email Stefan asking him to kick Synchro1 off of this forum if he continues.  If enough people do this then perhaps that will stop his unacceptable behaviour.

To everyone, I am sorry to even have to make this posting but I am fed up.  I am simply totally fed up and Synchro1's behaviour is totally unacceptable, and it's doubly totally unacceptable because he is a 50-year-old grown man.

It's time for this nonsense to stop.

TK, I can try your suggestion when I get the chance, but the waveforms looked to be as expected
when changing to different vertical deflection settings.

John.k1, the effect is very tiny at this point. Will need to see if I can increase the effect in any way first.
So far just a little oddity, and the effect itself is not the most stable. The waveforms looked somewhat different when
I checked again early this morning, but I haven't had time to try more measurements. Don't have a lot of time
for more tests this weekend, but will continue to test when I have time.

Milehigh, the connections were all good. I have already double and triple checked all connections with an ohm meter.
The CSR's are not the best, but they are carbon film at least. Only 5% tolerance. I will see if I can order some lower tolerance ones.

All the best...
