Yes i have thought of that but its difficult to do anything on that side without disturbing the resonance.
Any disruptions in the tank immediatly skyrockets the current drawn on the primary side.

I think of it this way.
The reactance of the primary has not changed, its still 2.98ohm at 50Hz.
So why did the current drop to 1/3?
Because the tank is feeding back 2.51A to the primary.
That is 7.5v in the primary so the powersupply just have to supply 5v into the 2.98ohm reactance.
Perhaps a current transformer in series with the supply and the primary could work.
Or halfwave rectified supply with a diode?Last edited by janost; 12-06-2012, 09:26 AM.

There is one more solution to what might be happening.
If the resonant frequency of LC combination is some hertz off from 50Hz there will be a phaseshift.
0 deg phaseshift is spot on and zero current drawn (minus losses).
90 deg would be as without capacitor, 100% currentdraw.
In my case this would equal about 30 deg shift and 1/3 current drawn.Last edited by janost; 05-03-2013, 11:55 PM.

i would love anyones thoughts on Tesla's patents 336,961 and 336,962
http://www.tuks.nl/pdf/Reference_Mat...sla_patent.pdf
http://www.keelynet.com/tesla/00336962.pdf
the parts explaining the self-excitation using auxiliary brush and coil in iron case,
the regulation using the automatic means,
the enhanced effects of the coil with reversed direction windings,
the outer ends of L2 being pos and neg rather than neg at center tap
the comparison between L1 Don used and the armature Tesla used
Understanding of these i believe to critical, as they are most likely the origin of our discussion... and what Don openly based his experiments onLast edited by mr.clean; 12-07-2012, 05:03 AM.In the beginner's mind, there are many possibilities.

Hi people, made a new bitoroid using the flyback ferrites..... Works better than the last, vid coming soon
ImageShack® - Online Photo and Video Hosting
Primary approx 40 turns 20 gauge
Secondary closest to primary is 6 layers of 22 with 26 gauge
Far secondary 4 layers of 22 turns same gauge
The metglass and iron failed, but this one is better than the last AND way easier!In the beginner's mind, there are many possibilities.

Do you still get same 2nd secondary power up effect when shorting one of secondary coils?

i ran out of wire or wouldve made both L2 the same, they are very close though,
its very cool!!... the far L2 does Nothing when primary is running, and the close L2 is basically what you would expect from a standard flyback i guess. BUT much improved over the first attempt overall!!
BUT the magic really happens when both secondaries are running or shorted as you said.
there are no gaps except for the 2 L2 ferrites have a layer of electrical tape to separate them so they act as 2 instead of 1 big core with worse eddy currents.
keeping them insulated from their contacting surface was good as i can see.
its still not meant for Big current though, this is a last resort after the Metglass didnt perform with the iron as i thought it might, and i just didnt feel like taking the first bitoroid apart but it can take more input before saturating, and provide more light than last time without peaking and leveling out, with my present electronics
its very cool how far secondary does nothing until its paralleled, or separately used,
the first secondary must be used, in order to make the effect of both secondaries effecting eachother, i think that's interesting. also i insulated each layer of windings on L2's, making it easier to maintain the same number of turns per layer, and from possible srcing between windings. i probably shouldnt have L2 ends wrapped together, but whatever easy to insulate those too
and on L1, the coil is one layer, then ran back on to of the first layer to begin again another layer, as i did in last time, and after so many failed trials, im gonna examine more Why it works better with the ferrites than with iron and metglass.
maybe ferrite and metglass? idk
either way, it seems there is no coupling from L1 to far L2, until first L2 is used, in which case the close L2 becomes the primary for the far L2, and they feed one another with their own building and collapsing fields
and i wonder what would happen with thicker L2 wires, with more intense magnetic fields
