Where to start after 11 months...

Right here right now.
Learned a lot build some circuits, all based on resonance of the bifilar coil, and under influence of the works of Nelson Rocha.

Then took a turn, looked into radiant energy, and saw It hold an important key in understanding the works of Nelson Rocha.
He shared, he discharged a capacitor really fast to get his effects.

Found a book, read chapter 1 several times, and new what to do.

Build a solid state hairpin circuit. A modern version of a Tesla device that showed radiant energy.
The Key, was to use a capacitor discharge, that is very abrupt, short, and with no polarity reversal, and the discharged voltage should be negative. I suspected this a long time, And Nelson confirmed.

Bassicaly build a boost converter, with a n-mosfet and a bifilar coil. but its switching high side, and therfor needs a pulse transformer.
Learned al this by reading a lot, and pushing myself. And it works.

The negative inductive spikes are charging the 2 series capacitors (together 12nF) to -600V
Than a second mosfet is used to discharge the capacitors very shortly, around 60nS.  also with a pulse transformer.

Inbetween the 2 series capacitors, Tesla used his stoutbar. But I placed a bifilar coil.
To cancel out the polarity reversals I placed a diode in parallel with the coil.

The effect is that the dielectric field of the bifilar coil (its strongest property is its increased capacity to store enrgy in its dielectrcic field), is suddenly changing voltage, creating a vacuum in the Aether.

This Impulse (not a 50%duty pulse, but 60nS impulse) is bringing a secondary, parallel stacked similar bifilar coil into resonance.

So far this was hard work to realise, but worth the effort.
First I tried -100 to -200V discharges, nothing special happend. than -325, still nothing, this was my max, due to the build in protection for the mosfets.

I decided to go Bold, and removed the TVS diodes protecting the mosfets. The mosfet could handle 650 V so I needed to be carefull.

I tuned it to -600V discharges, and things happened that didnt happen before.

Normally a resonant coil, is more or less in stand in reaching its maximum voltage, is my experience.
And normally, the resonant frequency is fixed. it doesnt just change, as it is depended on the inductance and the capacitance of the resonant coil.
I tuned the frequency of the coil Way down with 44nF (if I remember correct) in parallel. Much more than I useally used, but this was needed to get down low.

The stange thing, is when I tune into the resonant frequency, I expect it to stay fixed. but it didn't the frequency shifted. Also the maximum voltage dropped down. this al took a few seconds. Very strange.

Anybody seen this before?

After retuning, I noticed the same, and again and again, undtil I reached a much higher frequency. and voltage.
A rise in resonant frequency  is normally related to less inductance, or less capacitance. So what is happening here?

If I than, after retuning several times, turnoff the system, and after a few seconds turned it back on, It was completely detuned again. I had to go way down in frequency, to find the resonant frequency again.

So What is this? It seems the radiant energy slowly builds up (also described in the book) and influences the resonant coil.
As if the radiant coil, creates a vacuum that sucks in the capacitance/charge of the resonant coil, mking it shift in energy to a higher resonant frequency.

I made a video of the effect.
after this, I played in another setting, and the voltage suddenly went way under the -650V mosfet maximum. And they are now killed. Luckily I have more. But maybe I need to look for an even higher rating.

So far so good! :shocked:

The capacitor discharge gives the biggest voltage rise in the resonant coil, when it is tuned into the zero voltage phase, where the voltage of the resonant coil is rising.  So at 0 volts disruptive discharged, gives the highest voltage rise.

This is different than it is with resonance created by a 50% duty cycle (magnetic) pulsed primary coil.
then the maximum voltage rise occurs, when the pulse starts at maximum voltage, and ends at minimum (negative) voltage.

This implies, that If I want to combine these both processes, I need a 90 degree phase difference between the 50% duty cycle pulse, and the 60nS impulse. This way the resonance from both processes is constructive and additive. At least, that is what logic would say.

Another Idea, is that the magnetic induced resonance, when at 0 volts, has a maximum magnetic field. when combined with a voltage, it should provide power. as power is current (magnetic fiedl) times voltage (dielectrci field).
But this logic is flawed.
Current is an indicator of the rate of loss of the dielectric energy, into the magnetic field.
the power, seems to come, from the voltage, combined, with the radiant energy.

So What if the resonance created by the disruptive discharge isnt transforming between dielectrcic (voltage) and magnetic field energy, like the 50% pulsed coil, but is actually non magnetic... resonating with a differnt field...
What If.. the magnetic vortex, is not there, but instead, a ring vortex has formed.
Due to the instand impulse, that is to fast to create a magnetic vortex, but is so fast it creates a ring vortex.

what If...
What if.

One thing I'm sure about, is that the magnetic field of the 50%duty cycle pulsed coil of the negative boostconverter bifilar coil, needs to be combined with the radiant energy stream, and that the combined stream gives rise to a potent form of resonance full of power.
That only need to be rectified. stored in a capacitor as DC, and used for whatever we need.

One more thing, that Nelson rocha Said, and I suspected.
When a capacitor is overcharged with a negative votage, and internally discharges, it is less destructive to the capacitor.

When we follow the logic of pressure, it makes sense.
positive voltage, creates over pressure, and the cap explodes.

Negative voltage creates a vacuum, and the cap implodes.

An implosion from under pressure/vacuum between the 2 capacitor plates,
seems less destructive, than an explosion from over pressure.

The resonant frequency is shifted by the radiant energy, as can be seen in this video:

https://youtu.be/vRs5iDpFIeM

has anybody got a clue what is happening here? seen it before?

The video is unlisted, and maybe I'll transform it into a proper video, and post it on my channel for all to see.

Yes I have seen it--sent you an email.

Why it is drifting frequency is not known though--possibly due to the MOSFET heating up?  Or maybe something else...

I think the shifting is due to the heating up of the ceramic caps used, to tune the coil.
I hold my fingers across it, and the felt warm. The warmth of my fingers also changed the res frequency, so for my the mystery is solved

Replaced the mosfets, and put a large heat sink with fan on the mosfet used for disruptive discharge.

Further analyses re veiled that the inductive spike, charges the capacitors to fast, so I need to use larger capacitors. Why? Because a sudden change in voltage interacts with the resonant coil. I only want one disruptive discharge, and no other influences by inductive spike charging.

This makes it a bit more difficult. I still want to use enough negative voltage, but the energy level will increase. The mosfet is still cool, so has headroom. Maybe due to the higher energy, I can use less voltage. We'll see.

Further more, I played with only the discharged coil and the pulsed coil (no resonant coil) to see how they interact.

It showed when the discharge is at 90 degrees, or 270 relative to the 50% duty pulse, the voltage rises to the most negative (wanted) and at the same time, lowers the current draw.  the 270 degrees differ nce with the 90 degrees difference, is not clear, due to the impossibility to proper tune, and therefor needed to shift frequency, which influences the voltage rise.

I will use the 270 degrees radiant pulse. this way the magnetic field of the 50% duty cycle pulse, gives the resonance a kick, and then when the magnetic field is gone, the disruptive discharge kicks the resonance again. giving another push. If this doesnt work I will try 90 degrees.

TO DO:
1- add more capacitance to the hairpin circuit capacitors. These dont heat up, so ceramic is still a good low internal resistance/fast discharge option.Goal, is to slowly charge them with the inductive spike energy. dv/dt most be lower, to not influence the res coil.
2- change the resonant coil parallel tuning capacitors to polypropylene, so they remain stable with temperature.
3- tune res coil to even harmonic of pulse and impulse, so they become cummulative.
4. enjoy life :P

replaced the resonant coil parallel cap, with a 10nF polypropylene
added the 2 22nF ceramic caps to the hairpin capacitors, raising them to 2x 36nF giving a total of 18nF capacitance (was12nF) 50% increase.
giving 0,00324 joules per full discharge (but never fully discharges).

Also had another Idea.
If the north side of the magnetic field creates pressure, and the south side creates under pressure,
Than a negative discharge creating a vacuum, would assist the south side.

I feel its important to combine the effects of the magnetic field, of the 50% duty pulsed coil, with the radiant energy field, created by the inflow into the vacuum created by the discharge of negative voltage.

so with a 270 phase difference, it would be a pushing (north magnetic) combined with a pulling radiant field.
with a 90 degree phase difference in would need a south magnetic pulling  combined with the radiant pulling.

The goal still is to create a ring vortex.

With 10nF parallel  its resonant at 190kHz, but the resonant coil is now on one side, it could be improved when its in the middle of the 3 stack. but I'll leave it like this. its on the side of the pulsed coil, should be on the other side. so the 3 stack is:
 
50% pulsed coil
 impulsed coil
resonant coil

problem with 190kHz, is cant get low enough negative voltage. only 200V @ 0.7A 17V So need to get lower. I'll add another 10nF and place the coil on the other side of the stack

tuned it now with 2x10nf parallel, 20nF gives a res freq around 117kHz
21V dc @ 0.9 A gives a 300V pulse, still not enough, want at least 600V. mosfet stil cool
stack is now as described in previous post. (still wondering about reversing the resonant coil)
Will tune down to second harmonic, to get more negative voltage. dont want to add to much capacitance to the resonant coil.

second harmonic appears at 55kHz.
south pulling side is now facing the inside, where the impulse coil in the center is.
 current is lower now, but also the voltage, its eaten away it seems. only 100V
0.23A @ 20Vdc

dont expect radiant effects to mess it up with only 100V discahrge.
also dont expect the resonant coil to eat up the inductive spikes...
Why is that voltage so low...

EDIT: magnetic pulsed coil was in the middle :wtf:

ah noooo not again :roll:
took a small brake, rebuild the stack, played around, every thing worked.
then decided to bypass a resistor and suddenly, amperes jumped up.
signal is messed up.
somethings wrong.
need to figure it out. again.
ahhh. :(

Already ordered new mosfets and parts, so thats good.

will have to take a proper break now...

Did get -500V before the thing started to stop working. So thats good. Strange that the magnetic coil needs to be on the top or bottom of the stack to produce a decent inductive kick... but so it is

one more thing, adding capacitance did not result in slowly charging the capacitors, of the hairpin circuit.
instead, the increased capacitance didn't get discharged as much by the disruptive discharge, and kept their voltage, resulting in a low dV/dT while charging, this also is a good solution, as it doesn't interrupt the resonant sine.

Another Idea I'm playing with, is a variant that Tesla also used. only one capacitor is charged, and via a switch discharged through a coil.
switch and coil are in series to ground, parallel to the charged capacitor.

anther idea, is to not have a diode parallel to the bifilar coil (replacing the stoutbar) to stop it from resonating. Instead, use 2 diodes, to take the negative back to the cap, and the positive to ground. need to check if this works.

killed one mosfet it seems.
wonder why
but more importantly, could I protect it better, with 2 tvs diodes in series?
the tvs diodes i have start working  at 325V so 650V in series?
would be tricky since the mosfet is rated 650V...

at least I've seen the coil becoming resonant from the fast discharge.

Monday the mosfets will be in....
enough time to enjoy the weekend, and adjust the circuit a but more, so i can tune the discharge better

parts came in yesterday, nice and quick.
Just replaced everything and did some extra work to make life easier.
ready for testing.

but first enjoy life a bit on this sunny day

Replaced the other mosfet also. Both now on a cooling body with fan.
Every thing worked, played around a bit, added extra precision trimming pot and switches to be able to adjust where in the period, the cap discharged. Very nice everything works.

Then.. got a little bit to quick in switching.... and poof there went my mosfets again

 :emperor:

hard lessons...
I need to protect my mosfets better, or get a strict routine, where I slowly adjust the voltage....

Mosfets used are: n-mosfet

STF6N60M2

600V
4,5A
zener protected gate,
low capacitance around 450pF

diodes ar mur440 or mur460 (ultra fast)

Luckily only one of the two mosfets died :)
replaced it, and it all worked again.
did some tests, wrote down the results.

conclusions:
for the radiant and resonant coil coupled (magnetic coil moved away):
- radiant and resonant coil should NOT be reversed. best results when both coils are spinning the same direction.

- discharging from the outside to inside of the coil to ground or vice versa made no difference in the resonant rise.

Magnetic and radiant coil coupled, resonant coil removed:
- it did  matter how th coil was discharged, from inside to outside ground worked best, Tesla also grounded the outside of the coil. It gave a higher voltage (more negative that is) and pulled less current to do so.

Radiant coil uncoupled:
Feel a strange subtle field. not pleasant.

Will post detailed info and scope shots later.

More important the inductive spikes are charging the caps to fast, 2x 36nF in series were used. giving 18nF.
Removed all the caps (including the ceramic that I dont trust) and replaced them with 2x100nF mkp 4 wima caps. (polypropylene) giving 50nF so, around 2,5 times more capacitance.
Further testing will be done with these, but I suspect I will even need to use more capacitance. Slow steps are better tough...

Also need to order some TVS diodes, and put them in series to pretect the mosfets form overvoltage.

I'll take a breake now.

You may also want to give a try using some GDTs--you'll see them arc when their rated voltage is exceeded.  I'm not sure how "fast" they are, but surely as good as a TVS.  Neon bulbs in series can also work for this.  They will protect your transistors and have been used successfully for this for years.

Thanks Matt,
I think these I looked at the GDT before, and there rather expensive, limited in their use (break relative soon), and slow in the discharge.
the neons also seem slow. I think both are valid options, but I prefer the TVS as it is rock solid, doesnt breakdown, and relative cheap.
For now, I'm just being carefull, and for today its working

resonant coil is reversed! This is 3 stacked coils. magnetic pulsed, impulsed, and resonant tuned with 20nF parallel polypropylene

Res3c: 63kHz; 0.41A 17,5Vdc; +/- -500V discharge of 18nF ;  res=+/-150Vpp

res3 and res3b same settings, but low voltage +/-10Vdc

res 3 and res 3c: red line= resonant sine blue is discharging capacitor.

res3b: red is 50%duty pulse blue is discharging cap

magnetic pulsed coil is removed. radiant impulsed and resonant are stacked but reversed

Res4a 0.07A 32.3Vdc 122.3k?Hz, 1:1 probe 50Vpp resonant discharge is +/-130V 18nF

res4b: changed setup, coil now NOT reversed; 126.2kHz Vpp104V (double!) current 0.08A 32.3Vdc probe 1:10 discharge +/- 115V(215?)

conclusion: use the coils unreversed

no difference in voltage rise, when discharged from outside to inside ground or inside to outside ground. (does matter with pulsed coil).

discharge is every 2 periods, so @ 2x res freq.

4c: 1/2 res freq @ 62.75kHz. discharge every 2 periods=4x res frequency; 0.16A 32.3Vdc 157.2Vpp -330V discharge

4D: 62.51kHz slightly more voltage @1/8 of sine

5A: Magnetic pulsed coil 50% duty coupled with impulsed radiant coil. resonant coil not used, placed away.
North towards radiant coil. (no difference between south) 62.51kHz each 3 periods a discharge. Discharged from outside to inside ground.
0.52A 20.5Vdc
-400 V spikes, discharge -215V to -100V 18nF

why are these spikes not charging the caps???

5B only changed impulse discharge to inside to oudside ground (like tesla did)
0.54A (less!) 20.5Vdc ; Spikes are much less, cap charge more to -290V discharge -160V

conclusion: outside ground works best on radiant impulsed coil in relation to pulsed magnetic coil
are the inductive spikes directly captured by the radiant coil and stored into the caps???

5C used south side pulsed coil towards impulsed coil. no difference (but without 3rd coil)

5D radiant impulsed coil and pulsed magnetic coil separated (res coil also away).
0.24A 32.3Vdc 47.51 kHz eenry 3rd period discharged, at 270degres (75%. in the middle of off part).
This field is being felt as a subtle energy field. Feels strange, not very pleasant.
Still spiking and large stepped voltage. going to change hairpin caps to 2x 100nF

Removed the 18nF total series hairpin caps, replaced them with 2x 100nF giving 50nF total
used all 3 coils stacked in this setup. unmirrored.
6A  0.36A  14.7Vdc magnetic coil pulsed @ 90.1kHz  50% duty
Disrupted right on the rise of the pulse, part. Both probes 10:1 good discharge -500V
If I short the resonant coil, its sparking a bit.
Under short circuit of the res coil (load), current draw drops to very low.
resonant coil is 364Vpp

6b same setup
6c same setup
6D same setup but @ 0.43S 17.9Vdc

tried if It had some power. did charge 9uF to 430Vdc within 2 seconds. not much (2.88joule) power consumed 7.65W

Why are ther stil these spikes... why is the cap voltage not stable? Do I need to add some small caps, to capture those peaks? Do I need to further increase the capacitance to get a smoother charge curve? large dV/dT infuences the resonant coil, and radiant stream
