Am I missing something. Jacks last pic posted, seems to have bifi windings for 1 and 2, but I only see single wire on Itsu coil posted just before that.  ???

I noticed that too, there are way more loose wire ends then can be accounted for for only 3 coils  :o

Guess Jack is way ahead of me with his coils.

Here are some variations from the Utkin page.

About 3/4 down the page.

It seems you can try some of the things described with what you have, and if you want to try the others. ;)

No problem, this was experimental setup and coils were caduceus. So I could test plain coils, series caduceus, coils in series from both halves etc. All had the same effect, only the resonance point changed.

Itsu:

Thanks again for your ongoing testing.

Transformers can be modeled where you include parasitic capacitances and inductances.  The model can get very "deep" where you keep on adding parasitic components of smaller and smaller values that only come into play at higher and higher frequencies.  The model for the transformer ends up looking like a quite complex schematic diagram.  I stumbled across a great one once but the link is long lost.  These parasitics can explain the resonant peaks at high frequencies.

This looks like a pretty good link and I screen capped a graphic of a transformer from the link with the first-level parasitic components in the circuit model.

Core needs to be pushed hard with amps, frequency or number of turns. I made one test where I put step up transformer in front, ratio was something like 1:10 or 1:15. No idea really, it was caduceus primary (2*14 meters 0.31mm wire for secondary) and caduceus secondary about 2*20 turns, but did not count the turns for secondary when I made it. Anyway, result was that I did not get output halogens to light up anymore. In another test I used 25 turns for L3 (no step up) and again no light in the output, did not have resonance in L3 though so it leaked power. With 90 turns L3 it worked even without capacitor in L3. 90 turns was enough to block current at 11 kHz where the resonance of the L2's were in my nanoperm setup. Was not able to test effect of frequency, but it should be obvious that frequency affects too.


The whole idea here is to create two opposing magnetic currents/fluxes/'what ever you think there occurs in the core when coil is energized', which then amplify each other. The secondary resonance I discovered by accident. When resonance is in place, then trying to increase power in the source (crank up the volume knob) beyond blocking level of L3 has no effect. If L3 is monitored and power is taken then it should have no effect in the L3 because it sees two opposing 'thingies'. For example try shorting the output L2 with the bulb (bypass only the bulb with wire so result is LC-tank), or leave L2 with the bulb unconnected.


Ferrite E-I gave almost the same level of results, there I had to use 200 turns in every coil. With 50 turns I could barely light up output halogen and input side leaked power, did not know about resonance at this time though. I had three L2 secondaries and middle of the ferrite had the isolated LC tank. When I had 200 turn coils I knew about secondary resonance, haven't tried resonance using 50 turns and most likely I never will. I tested E-I also with two L2s having 200 turns (middle coil was unused) but I got no light in the output. I did not test if there occurred power transfer from left L2 to right L2. Most likely not because test with nanoperm with holes in it did not have power transfer in similar setup.


Now with core having 1000 permeability, 100 turn L3 does not block without capacitor. Or this really needs high permeability core to work with two L2 coils.

If parallel LC-circuit blocks certain frequency, does it mean that core is saturated when this resonance occurs ?


If not, then L3 needs to be done so that it blocks current flow at the secondary resonance frequency and only then capacitor can be used to for matching resonance in L3. This is how I obtained turns to use in L3, had resonance in L3 only once though.

No, but if saturation does happen then it will increase this resonance frequency.

The theory/idea behind this is in this patent.
Hmmmm,   a "solid state electric generator" he,  sounds interesting.  Seems that jack has already the main ingredients.
Square wave in, (in resonance), sine wave out?

Regards Itsu
Yes, but it can also be a saw/triangle/sine wave in, sine wave out, because the primary LC tank will create a sine wave out of anything at the input of this generator anyway.

The whole Gunderson generator can be put into a large pot-core in order to close the magnetic flux paths as illustrated below.

Thanks, nice drawings, but looking at the size of the pot-core, this will be miniature / precision work.

"amplify each other", well normally you need input for something to amplify, so i am still not sure how this should work.

Anyway, i finished the 3 coil setup on the nanoperm core, any suggestions on how/what to connect to fullfill the above situation?

I wonder what is the largest pot-core available commercially without custom manufacturing. 150mm diameter would be nice...

Does anyone besides Itsu wants to contribute and search the net for it?

Also, look on Alibaba for a Chinese connection ;D , where some companies will send samples. ;)

Thanks, but those links do not answer the question what is the largest pot core out there.
That would require looking through a lot of commercial offers - a time consuming process.

e.g.: Page 26 of this catalog shows a 45mm OD pot-core.  Where are yet larger pot-cores available ?

Here is a 70 x 42mm pot core at ebay:

from this site it seems the OD 114mm is / was the highest pot size (but other manufacturers may have produced bigger):
