Confirming the Delayed Lenz Effect

[madddann]

Hi gotoluc!

Could you please make another scope shot with the load 20W or 50W (i'm sure you have some automotive lightbulbs laying around) and with the capacitor retuned, so we can see what the power curve looks like?

IF WE WANT TO KNOW WHAT'S REALLY GOING ON LET'S LOOK AT THE (SOURCE) INPUT REACTION TO LOADING...

DC INPUT CURRENT ON IDLE (NO-LOAD) = 0.4 A
INPUT POWER ON NO-LOAD = 4.88 WATTS

DC INPUT CURRENT ON LOAD = 1.13 A
INPUT POWER ON ON-LOAD = 13.8 WATTS

INPUT POWER INCREASE % NO-LOAD TO ON-LOAD = 182%

THIS MEANS THAT THE INVERTER HAS TO WORK HARDER TO DELIVER POWER TO THE LOAD REGARDLESS OF WHAT THE SCOPE SAYS...

MY SUGGESTION IF I WERE YOU WOULD BE TO DELIVER POWER ON THE AC SIDE WITHOUT ANY CURRENT INCREASE (REACTION) ON THE DC SIDE

PS

IT WOULD ALSO BE GOOD TO KNOW WHAT THE CURRENT AND VOLTAGE IS TO THE INVERTER WITH NO COIL ATTACHED AND THEN WITH COIL ATTACHED?

Hi Thane,

I've been winterizing my sailboat and cleaning and re-packing my storage as I'm flying out of the Country this Tuesday.

I also returned the sine wave Inverter.

It uses 400ma @12.5vdc with nothing connected to the outputs.

Sorry but the time I had for testing is over for at least a month if not more

I'll be keeping an eye on the topic from abroad. However, Internet access is very limited where I'm going to be.

Talk to you in some time

Luc

I have a video I did some years back (Jan 3, 2009) of a coil in resonance setup this way. It was a spool of speaker wire.

Link to my video: http://www.youtube.com/watch?v=auFYEFBrwls

Anyways, there is a mutual Inductance and Capacitive coupling between his signal generator hot and ground. This YouTube experimenter just can't see the Current because he's using a moving coil Amp meter which is fine for low frequencies but it's not going to show any activity at 300KHz

He would need to use his scope and a shunt resistor to see the AC current at these frequencies.

Maybe you should try this driving circuit from Romero at your secondary, it looks promissing...

Generator Coil Speedup Circuit Simulation

In some of the 'acceleration under load' videos Romero showed this attached circuit to be responsible for the speedup effect.
I did a simulation of that replacing Hall sensor with a zener diode.
The result is blinking led with power disipation shown on the right graph and on the left we've got power taken from the rotor...

This can be done in 1:1 transformer too, I think so...

This sim is just an example. You would have to play with parameters (right mouse button on a componetnt to edit) to make it right...

Interesting circuit idea and Sim 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.
