Rene/Meissner EMF Higher Voltage Charger Variant

[SkyWatcher123]

Hi gyulasun, thanks for the good information.
How many coil turns would you suggest i remove, as of now, each strand is about 3 ohms and we have 11 strands to work with.

I have some 2 in 1 diodes, the 3 pin ones i salavaged, probably schottky, will check later and see what they are.

I have on hand the NTE331 NPN i can try again and also found two STPS3045CW power schottky rectifiers, though they only handle 45 volts.
Also found a DSSK30-01A.

Well, the magnetic permeability of the ferrite core is not known (by me at least), this is one thing.
The other thing is the coil inductance without the core is not known either, an L meter would be useful
to check if you have access to one. 

A possible approach without an L meter would be this: remove 1/4 of the total turns you now have for
the 11 strands and try to get similar input current draw by plugging in the ferrite core.
Then try to remove one layer or two only if the core is still not nearly fully inside the bobbin to get the same
current draw at the same input supply voltage of course like you had with the air core.
The goal would be to have similar coil inductance for the 11 strands with the inserted core like the air cored coil
with its longer wire length has had so far, also for the 11 strands.  The current draw is mainly determined by
the primary coil AC impedance and this latter is governed  by coil inductance at a specific oscillator frequency.

Hi gyulasun, thanks for the helpful information, i will probably try those things, though before i alter the coil, i would like to try a different circuit with it.
I'm going to see if i can get the Johnny aum circuit working with this split negative setup.
It may give greater efficiency and does not need a dedicated wire for feedback.
Similar to this circuit drawing.

Hi Skywatcher,

I agree it is not good to unwind a coil which already works fine as per your findings.  A better approach is
to make another similar coil with less number of turns from the same sized wire and using the same sized bobbin
if you have these resources.

I watched two videos from Johnny Aum and attached one of his circuits you surely have seen or even tested. 
I think what he wrote in the top part of his drawing :  "This device works without exterior source of electricity,
or anything."  is a bold statement and most likely unproven.
It is okay that the flyback pulses from the coil may charge the batteries via the LEDs but I doubt the batteries
would maintain their initial charge continuously for long weeks or months (and while charging even a third battery).

Hi gyulasun, thanks for sharing that drawing.
I might be able to make another 12 strand coil, i still have the 5 strand coil i made previously, could just add to that one.

I mentioned johnny aum, only because he uses a similar main oscillator to the one i posted.
I would only be using the oscillator, to try and integrate into the rene split negative setup, no leds or anything.

The load test finished on the previous circuit, around 70% given back from the battery, not too bad, considering that circuit at 25 volt input, is only 40% efficient.
So I'm wiring up the new oscillator, using the NTE331 npn and the NTE332 pnp, maybe it can be more efficient, if i can get it to work properly with the split neagtive charging setup.
