advancing the Solid state Tesla hairpin circuit


« Reply #225,  »
just tested the counter wound bifilar coil as L1, and it works. lower voltage needed, and naturally a higher current.

Magnetic field is south on both sides (or north if polarity is reversed).

If Ken Wheeler is right, the south pole is centripetal, a influwing vortex, north is a centrifugal outflowing vortex.
Both sides of the counterwound bifilar coil have a inflowing south vortex pole.
The north poles  are squashed in between the windings, and from what I have seen from the ferro cell, when two magnets are in opposition a new dielectric field is created in between them. so now we have a south pole vortex on each side of the pole and a dielectric field in between the windings.

Also could mean, with south on the inside, a inflowing dielectric field is generated bewtween the windings, and outlfowing north on each side...

the series connection can be chosen on the outside or inside rim of the bifilar coil. The voltage difference between the supplied voltage/current will create also a local dielectric field. but this one will probably neglect-able.

compass needle shows same poles on each side of the coil. at the outside rim, there the needle also deviates, showing a influx or out flux. interesting stuff...

I worked out several scripts for new videos and have started recording new video material (for my master ivo channel).

stepping back from the research was a good choice.
my mind is becoming clearer again, and I have better perspective on whats going on.

no promises, but I intend to make multiple videos, showing/explaining
the fields of the coil
the series resonant bifilar coil
the impulsed series resonant coil

cap impedance change from impulse
« Reply #230,  »
I'm still working on a series of new videos. making good progress.
While in production, I do not experiment, and this bring my mimd into focus. A lot becomes clear.

One of the things I encountered, and showed in the radiant power video (master Ivo, youtube) is the reduced power draw when L1 and L2 are coupled. And still it produced large Impulses.

These Impulses are a representation of the magnetic field energy, So with the reduced power draw, they are over unity by them selve (I think, but need to test).

These Impulses can charge up caps really fast, as if the caps are much smaller.
Tesla has a patent on this 462418

I really like to see how this all works. I have many ideas, and will test in the future.
but for now, I stick to the videos production.
Tesla exta coil, as impulse amplifier, through higher harmonic
« Reply #231,  »
First video is finished. Got several more im production.

meantime, I have been thinking about how to amplify the impulse voltage.

It seems Tesla's "extra coil"  holds the answer.

instead of magnetic coupling amplification, which loads down the source,
I will use the loose dielectric coupling.

this means using a resonant coupled coil(secondary) .
the resonant frequency of the "extra coil" will be a higher harmonic of the series resonant L2 coil (primairy)

due to the higher frequency, the impulse duration will be shorter, and the impulse voltage higher.

the L3 could be grounded, on the series resonant  L2, between the l2 coil and the series tuning cap (where the resonant voltage meets the impulse).

I wonder if L1 then also acts on a harmony of the l2 and l3. but thats for later.
Tesla's extra coil, as impulse magnifier
« Reply #232,  »
 I have kept my promise to myself  to produce 3 videos. I have a few more scripts. But first I need to do some experimemts.

Tesla's extra coil had very little capacity and the resonant frequency of it was much higher then the secondary.

I hooked up L3 (no parallel cap) to L2.
L3 (outer rim) connects between L2 and l2's series resonant tuning cap.

So L3 rings, from the impulse.

First test looks good. Indeed impulse is amplified in L3 (extra coil).

trick is to tune the impulse duration to L3's half period of its resonant frequency. Which is a lot higher around 600kHz. it needs a 700nS impulse to fit perfectly, and make it ring perfect, but my impulse right now is to slow. 1.2uS  but I can fix it.

L3 is ringing pretty hard already. But if the impulse matches it should be even better.

magneto dielectric ringing
« Reply #233,  »
To generate the impulse, I couple L1 and L2. as showenninnthe radiant power video, this reduces the current a lot. I suspect It also slows down the impulse a bit.

It now runs at around 2.5W giving -700V impulses 1.2uS at aroumd 58kHz

that 700v impulse is amplified in L3 to around - 1200V due to its ringing, its lower capacity and thus higher frequency.

I wonder if the ringing is magneto dielectric in nature, meaning, longitudinal ringing, whereby the current and voltage are in phase. (also as shown in radiant power video).

I wonder how quick a cap will charge, if I tune L1 (impulse duration) L2 (base tone) L3 (higher octave ringing from impulse).

But first I need to tune. In the end Steinmetz was clear, I need a ringing oscillation that rises in amplitude.

On this subject:

^ This is what I was aiming for, I wound a coil geometry with the shape of two colliding vortexes in mind, similar to what you are discussing with two north pole inward bifilar pancake coils.

Interesting state occurs where during resonance voltage sticks at a low level depending on the load attached, but the load would be fully powered so long as the load is resistive in nature.

If the load is big enough the local temperature drop will be noticeable, your observations with your heat sink line up with my own, once that is achieved keep adding load to it, when you have enough load parts of the system will get cold.

What MOSFETs are you using currently? Wattage rating?

"local temperature drop"
can you go into that a bit deeper?

So you read room temperature, and it drops? How much how quick?

Its not a hot mosfet running less hot
