Confirming the Delayed Lenz Effect

[kEhYo77]

Do you think it is realistic?... if so, I was able to tune it to return current   You just have to wait 3 or 4 minutes till it reaches the 44 Watts range.

Let me know what you think

Well it seems to be working in this video so I think it is worth trying.
Speed under load!

Like I said, you have to play with the parameters I achieved even higher output at some point but we have to check it's performance in a real life setup.
Right now the inductance of the transformer is a bit unrealistic but this circuit is just a base to work on.

Hi everyone,

I couldn't resist to test kEhYo77 circuit simulation in real time.

It's now 2am and I fly out of the Country this afternoon, so I may not have internet access for a few days unless I get some free wi-fi in one of the airports I'll be going through.

For the test I used another Toroid that I have that has Dual 120vac coils which are 300mH each and 2.3 Ohm DC Resistance

Also, I only noticed (after the electronic store was closed) the Transistor was an PNP and not your standard NPN. However, I manage to find an old one in my salvage stuff. It's model A671. Probably not the best but it works. I tested its hfe and it about 67 to 70

Below is a link to the Simulation with all the correct values of components that I used. I also used 60Hz grid at 12.25vac adjusted by my variac.

The scope shot below is with a 1 Ohm shunt resistor on the green trace. The the probes are setup in the standard way that I have been doing to measure current and voltage (yellow) on the input side.

I used my digital meter on the output side to measure the voltage across the 10 Ohm load Resistor. It is at 4 Volts AC = 1.6 Watts. I also included a second scope shot by moving the yellow voltage probe across the 10 Ohm load so you can see its wave form.

I did include the scopes Math function in the first scope shot as you can see but I'm not qualified to do the power calculations. Please help as I don't know what to do with Vmean with Negative reading

It definitely looks interesting

@Luc I'm glad you tried it. It is very interesting indeed.
The tuning should be more like this, I think:

Re-tuned Gotuluc's setup

A added resistors responsible for DC resistance of the transformer windings. I removed the zener diode too.
Now it seems that we have a win-win situation, where power is being returned to the grid (-17W) and at the same time power is being dissipated at the load (10W).

This circuit is much closer of the Transverter + Diode Plug extration (sine wave clipping) I have read once again over +200 pages of RV document that I keep inside my PC...  basically the RV circuit use CAP transformer and resonance, tuned in very High Q mode... Then they extract power from CAP with some transistor (like here) when the capacitor is at full voltage and current at 0, so extraction from resonance doesn't affect it... The input power remain reactive (like here, according your red curve) while delivering real joule to the load... A formula (based upon empirical experience) give you the maximum amount of extractable energy in caps because if you over extract then you start to kill resonance oscillation... The formula is 0.618* the circulating VARS in the trafo without the diode plug...
And last Vmean is negative but very small it could be with some imprecision here, the most important is the input is PF=0 here see the red curve energy back and forth to the source !!!

Hi Kehyo

Thank's for the circuitery

Just a question about the transformer. In your setup you have 300 H and not 300 mH. Where do you find a so high inductance transformer ?

I have tried the circuit in the sim with 37 mH and 1.5 Ohm resistance and i can not go under 500 Hz at 10 volts input sig to get a higher output to input result in the sim.

Can you confirm the transformer at 300 H ?

Thank's

Laurent
