Hi all, Hi seychelles, thanks for the link, i have seen some his videos previously, looks good.

I am testing another circuit version, this one does not use any splitting of negatives or positives.

It does seem the most efficient so far, probably would be even more efficient with ultrafast diodes used as a full wave bridge, i don't have 4 matching ones at the moment, i will get them though.

Also, the secondary coil with the full wave bridge, gives the battery a normal pulse, then the radiant collapse, so gives us similar function as the rene circuit.

It also prevents any battery damage from too pure of radiant spike charging.

A battery load test will tell for sure though, as to the true charging efficiency.

Hi all, testing this circuit at the moment, seems even more efficient.
I figured it will get a direct pulse charge and then the spike recovery and also any ringing will be captured effectively as well.

Hi all, I had a thought today to try a little different circuit design, again, based on the Rene split negative charger idea.
The thinking is, the current flowing through the primary oscillator coil, creates a magnetic field by consequence of this current flow.
So why not take advantage of that and induce current into a secondary coil with a full wave diode bridge back into the same charge battery.
So 1 pulse flows through the primary coil and then into the 12 volt charge battery.
Simultaneously, another pulse flows through the secondary, into the bridge and into the same charge battery.
We get another pulse from the collapsing of the coil fields, through the bridge and into the charge battery again.
I've been testing the circuit for a little while and it is performing very well.

Hi Tyson,

My thinking on your thinking is the following  8)
If you use 20V supply voltage, then the paralelled primary coils receive 20V-12V=8V and this 8V is transformed to the
also paralelled secondary coils, a normal 1:1 transformer, right?  This means that after the full wave bridge the remaining
DC voltage level (just from the current flowing when the transistor is ON) cannot really charge the 12V battery because
the induced voltage level is surely below 12V 'by default'. 
To remedy this, you may try to connect two - two paralelled secondary coils in series, this way you would have
a 1:2 step up transformer from the 12V charge point of view because the roughly 2 x 8V minus the diode bridge drop
of 1.3 - 1.4V will still be higher than the 12V battery level so charge current could flow into it.  (Of course,
half of the ON primary current will be available for this charging due to the 1:2 step up ratio.)  Using Shottky or
Germanium diodes helps reduce voltage drop or as you already used paralelled diodes to reduce the voltage drop.
OF course, this is to be tested how worthy it may be.

Hi gyulasun, thanks for the helpful reply.

I have the boost converter set to 30 volts, so the secondary coil is pushing charge through the bridge and into the charge battery, minus losses.
Though at 30 volt input, the input power is higher at start, until charge battery reaches a high enough voltage, this to speed up the final peak charging phase.
I will also try the series coils for 2:1 step up ratio, that could be more efficient.

The full wave bridge is GBPC1506W, rated for 600 volts, avg. current 15A, surge 300A, 1.1V forward drop.
peace love light :)

Hi Tyson,

Well, had you included the 30V supply in the schematic I would have considered it  ???   you did include the 20V
in two schematics preceeding the last schema above, this is why I thought you used 20V again. 
At 30V supply  the secondary coils voltage transformered during the ON time of the primary coils is surely
higher than the 12V battery to be charged so the 1:1 winding ratio sounds ok.

But it is always good to tests some variations like making two - two parallel groups from the 4 secondary coils
and connecting these groups in series as I wrote yesterday.   

Regarding the diode bridge, quasi all such high current high voltage bridges are intended for mains frequencies,
their switching speed may not be sufficient for your circuit that may work in the some kHz or ten kHz range. 
https://www.fairchildsemi.com/datasheets/GB/GBPC1506.pdf  data sheet deals with 60Hz frequency (Fig 1 and 2).
Maybe it would be worth to assemble a diode bridge from 4 fast diodes like the UF4007 etc.

Also, another variation here would be to use a full wave voltage doubler instead of the diode bridge. It has only two
diodes instead of 4 so half of the voltage drop can be saved versus the 4 diode bridge.  The price to be payed for this
advantage is the need for using two electrolytic capacitors, see this link:
  http://www.augustica.com/full-wave-voltage-doubler-tripler-and-quadrupler-ezp-36  and I attached how it would
look simplified for your circuit.  C1 and C2 could be any value of 100 or 200 or 470 uF and higher,
working voltage should be at least 100V or higher.  If you use this doubler, all the 4 secondary coils could remain
connected in parallel of course.  In the voltage doubler, each diode could also be made of 2 or 3 fast diodes (UF4007)
connected in parallel to make the forward voltage drop even lower for each.

Hi gyulasun, wow thanks, great ideas.
I'm testing the the 4 strands idea, 2 sets of 2 strands in parallel, then those in series, that is working far better.
Am able to lower the voltage to 24 volts input and the diminishing voltage usable for the oscillator, does not effect the charging nearly as much.
Yes, the high speed diodes is planned, only have two matching ones at the moment, so your full wave voltage doubler is something i can test.
I will keep the series/parallel secondaries in place, then lower the input voltage as far as i can, then use the voltage doubler and see how that works in comparison.
Thanks for all your valuable contributions gyulasun.
peace love light

Edit: i've been using air coil mode for these tests

Hi all, Hi gyulasun, so far, with the 4 secondary strands in parallel and using the full wave voltage doubler, the output seems very good.

And the input is only 4 watts, 25 volts at .16 amps, though that will fluctuate as the charge battery changes in voltage.

Very impressed so far, will do a few proper load tests for watt hours to see.

I used for the voltage doubler, MUR460 diodes and 200v 470uF polarized capacitors.

Hi Tyson,

Nice progress, there seems to be a few refinements could be done.

One such possibility is to reduce the number of turns for the 12 strands and use the ferrite cores to have
similar inductance the air core coils have now. Less wire length involves lower DC resistance and helps get
the desired increase in L/R time constant which reduces overall coil losses, see the link on the L/R time constant
in my reply #6, previous page.

Another possibility is using still a better choice for the 2 rectifier diodes. (I do not mention the transistor type
because it was addressed earlier).  On better diode choice I mean the followings.
Data sheet says the MUR460 has about 0.74V forward voltage at 100mA and 25°C (Figure 6 on Page 6,

https://www.onsemi.com/pub/Collateral/MUR420-D.PDF ) Should you have had a MUR420 type instead (200V, 4A)
the forward voltage drop would be about 0.64V at 100mA and 25°C (Figure 1 on Page 4) and for the two diodes
in the voltage doubler this means 200 mV less overall voltage drop at 100mA forward current.
A similar behaviour is found for the UF4003 diode (200V, 1A) versus the UF4007 (1000V, 1A), from data sheet
https://www.fairchildsemi.com/datasheets/UF/UF4001.pdf  Page 4 in Figure 2, forward voltage drop of UF4003 is
0.6V at 100mA while for UF4007 the drop is around 0.9V at 100mA.
You may think the 200V rated diodes prove to be underrated for the voltage spikes at the switch-off moments,
this can be true when the oscillator is run without any loading i.e. no 12V charge battery is connected.

Now have a look at this Schottky diode type SBR30300
https://www2.mouser.com/datasheet/2/115/SBR30300-464761.pdf this is a 300V, 2 x 15A diode and
it has 0.42V forward voltage drop at 100mA current and at 25°C (Figure 2, Page 3).
Because the two diodes are very closely matched, they can be connected in parallel to decrease
their forward voltage drop by a few percent (8-10%).
Unfortunately, such diode types are rarely found in common appliances one could scavenge them from.
In PC power supplies similar double Schottky diodes are surely used at the secondary side but their reverse
voltage ratings are around max 40-60V.

Keep up your your devoted work.

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.
