COP 17 Heater | Rosemary Ainslie

[poynt99]

Poynt - if you're still there - could you please post those details again - any that are appropriate. I hate following links because it kicks me out of this connection and then it's time consuming to cross reference. So - if it's not too much trouble.

How does this sound: Describe exactly what measurements you would like to see from the simulation, and I will reproduce them.

We also have poynt's COP meter that he donated to every one and can add that to the testing of Rosie's if needed, i prefer REAL work and testing in the incubator circuit. Again my money is on Rosie guys.

Ash,

It might be applicable to Aaron's and Rosemary's circuit, but a rectifier/filter circuit would need to be added. Their circuit presently has no DC output. I assume you are referring to the "Is COP>1?" diagram at the end of the "Cheap Oscillators" / MRA document?

[poynt99]

In reference to my last post, here is a question to Aaron and Rosemary:

We agree that neither of you have any problems with the notion of using a flyback diode to help capture/recover/regenerate (insert your term here) some of the coil energy back to the source battery correct? Also you are ok with using the flyback output to charge a totally separate battery correct? And it is one of your claims that battery recharging does occur with or without the flyback diode present?

Will you possibly allow the following proposed method to determine COP>1:

Use a transformer and full wave bridge off the load coil to convert the AC voltage across it to a filtered DC voltage. We would use a transformer so that the DC output voltage may again be referenced to the source battery ground. Then this output will be applied to the source battery in the hopes that it will gain charge?

This of course means placing the transformer primary in parallel with the load coil.

The use of a transformer may make things a bit lossy (depending on your slant here), but if COP>17, this slight loss should be more than compensated for to keep the circuit alive and running indefinately.

Just a thought.

Hi everyone,

I forgot, the other thing I'm going to try is the rotation of the "Load" 10 ohm wire wound resistor ...... maybe the wire winding direction may have some gain/loss difference in the circuit operation ?

Yup here is poynts one

Let me know how you need it set up poynt, great another diagram you need to draw . Our one will utilize Rosie's circuit with solar power

Yes

Use a transformer and full wave bridge off the load coil to convert the AC voltage across it to a filtered DC voltage.
Not sure what a 'filtered' DC means. Presumably just that the AC changed to DC? I know from personal experience on AC tests that there's a marginal loss through those diodes on the bridge rectifier. Doesn't matter much on high voltages but not sure of the effect on lower values.

We would use a transformer so that the DC output voltage may again be referenced to the source battery ground. Then this output will be applied to the source battery in the hopes that it will gain charge?
Not sure why you need a transformer if the inductor itself generates the required.

This of course means placing the transformer primary in parallel with the load coil.
Ok. We've tested this variation but the current flow was quite extreme.

The use of a transformer may make things a bit lossy (depending on your slant here), but if COP>17, this slight loss should be more than compensated for to keep the circuit alive and running indefinately.

Poynt - are you proposing this circuit to be simulated or actually built? Quite frankly I'm having difficulty understanding the rectifier arrangement and where you'll return the energy - another battery? - the source? Whatever. Can you give us a schematic? And why do I get the impression you've done this? Indeed I'd be interested in the results. I'm a sucker for punishment.

But I would very much appreciate the data from Aaron's last test and from the published experiment posted here for easy reference. Please oblige.

Ash - you've got to be one of the kindest people in the world. I just hope your optimism here is rewarded. If you ever want an example of aperiodic oscillation you should check my own optimism gauge. Definitely in resonance.

[witsend]

Harvey - the load resistor was always placed within 6 inches of the MOSFET and more or less parallel.

I get it that you're trying to determine what actual energy is lost to the battery during the 'off' period? Presumably this question can be resolved by checking current flow through the MOSFET. In one of Luc's test he put an LED - or it might have been a torch light - at the source to determine this. But he worked at lower frequencies. In any event - I think it's worth doing this test with the shunts at the three legs.

Just so comforted to see you're still grappling. I had an idea you'd signed off.

Sorry Poynt - I missed this. Many thanks. Ok. Can you firstly do a repeat of the published circuit. Presumably it may require those amendments to the switch? Or do you even need a switch on a sim? Then at 3% ON - waveforms over the shunt, wavforms over the load resistor, waveforms over the battery. And some quick reference to their average values and the wattage levels of energy dissipated/delivered.

Then the same on Aarons new circuit.

Many thanks

Hi witsend,
speaking from different Resistors, what did the scopeshots look like what you got by your Tests,
they been simialer to the one we have here?
Thanks.

Joit - they were all over the place with a frequency that we could only gauge on an average. Actual frequency ranged between about 10Khz higher and lower. The spike values also varied but never exceded the voltage of the spike generated at the switch. In effect it looked like bad copies of the switched cycle. At the actual switch one could see a periodic waveform. Then these 'ghost' waveforms between each switched cycle. Hope that helps.

As mentioned repeatedly - I am just so sorry that I never photographed this.

[Joit]

Hi witsend,
Thanks and yes it does, especially this 'Ghost' waveforms sounds interesting.
But my Point is, they been at the Quantum article similar to this one we got?
Because every Load gives a specific Waveform, even more at pulsed Circuits.


@Harvey it sounds good at all, i guess, i go look for some loose Wire to play around with it.
FEMM4.2 is a Magnetic/Eleectrostatic Sim, when you are interested,
but i doubt, it can simulate this inductive Influence you did mention at the Gate from a Transistor.

Not sure which waveforms you're referencing. If it's Aaron's 'sine wave' number - definitely not. If its the waveform on your video - yes, close. If it's Aaron's earlier waveforms they're similar.

I like the fact you're winding your own resistor Joit. You must try and use thick wire - I always found it helped. I don't think it needs a core. I'd be most interested to see this.

[Groundloop]

Done soldering

Hi Group,

Finally, my RA circuit is soldered and ready to be tested.



The heat sink to the right is my 0,25 Ohm 1% accuracy shunt resistor.
(This resistor is not wire wound.)

At the back you can see my 80 Watt 10 Ohm wire wound load resistor.

BTW, GOTOLUC has approx. 19 of these PCBs to give away for free.
Just PM GOTOLUC is you want a PCB. (The PCBs are without parts.)

Regards,
Groundloop.

[witsend]

Groundloop - it looks really, really pretty. Be most interested in seeing your numbers when you start testing.

And thanks again for going to the trouble. it's much appreciated.
