Well done Roberto,
nice equipment.

What is the Wattage of the bulb ?
Could you also everytime tell us, how many amps
you are drawing from the power supply ?

Voltage alone does not say much.

Now,how big is the heat at the MOSFETS ?

It seems you have the phasing of a musical chord.

Remember, if you ever have played music yourself,
if you hit on a keyboard a 3 tone chord and
have the amplifier set shortly before distortion you
always get into distortion when the right phasing occurs
as the chord then raises the amplitide and this distorts
the amplifier input....
SO you have the same effect...

Now you need to just sync the 3 frequencies to get the
highest brightness of the bulb all the time...


Do you see yet any power amplification ?
Do you already have any feedback coils in the design ?

Maybe you can post the circuit schematic, so we can learn from it ?

Many thanks.
Regards, Stefan.

*Again think that about half of the dissipated power vanish in heathing the power Mosfet's Heat-sinks...even"

If the heat-sinks are inside into the coil you can have this effect:

Yes, Roberto is probably wasting much energy in heating his metals like heat sinks
and MOSFETS metals via eddy currents...
Roberto, maybe you can check into this ?
Many thanks for this hint.
Now I know, how to get red glowing graphite rods without needing them to
fire up for electron emission, but that is completely another idea..not related to the TPU.

@mosfeteers

Question about the heat.

Why do mosfets heat up? Does the heat increase when you increase the frequency? I mean anything moving that fast will generate heat just by any internal movement in itself.

So what about this.

Let's say you wanted 999,999 hertz.

Will one mosfet generating 999,999 produce more heat then three mosfets that generate 333,333 each but offset from each other by .000001 of a hertz so you still get the 999,999 punch.

@marco

My dad had several of those exact tube cases full, tube tester, degaussing coil and all. Those were the days.

@eldarion

I think Roberto is already using isolated transformers to keep any flyback away from the power supply.

What do all those letters at the end of your sentence mean? lol. Just joking. I understand what you mean when you say "precious time", because it is. The younger ones don't know this yet.

I am happy you used the word "unlinear" as being a basis of your design goals. This gives you more control over the process hence it leaves less to chance.

You know I am not afraid to build things, but I know I do not have the EE knowledge or all the equipment to do the controls, etc. I have to be a realist. Right now I am concentrating on Erfinders Challenge (EC) and it is very very interesting to see all the different results with changing of components. Plus it is perfect for my EE (level 0). I have been working with motors, gears, relays and transformers always so this is just right. I am learning more now and also on how to better use my old scope.

You, otto, gk and others are the real modern day Teslas, doing the crazy hair raising stuff. What I can do is build a new TPU with some changes to your current build that I have been wondering about, and send it to you or anyone else closer to do the standard trials. I do not mind building even more variations, but my EE level is too low to appreciate the circuits.

Everything will fall into place as it should, by all intents. Some are looking at the small volts required to start a TPU, you and your valiant counterparts are working on using those volts to shape the 3 sisters, or two daughters, or one mother-in-law, lol, and there may be someone else required to build the loop. This is all part of it.

Granted, if there are any EEers out there that need something to do, THIS IS IT!!!!! AND NOW'S THE TIME............ Please sign in. After only two weeks of TPU boot camp you'll be ready to go to the front lines.

But let's just think for a moment. If one, two or three guys would concentrate on making the builds and sending them to a central location for testing, this would save the central EEer build time that could be better used to learn how to tame the beast. The central tester would ensure commonality in testing procedures. The builders would be responsible for building and documenting the build process, wire gauges, turns, dimensions, ohms and other needed general measurements, etc. We have to team up because guys like you that can both build and control are rare. I am sure there are more people here willing to help as they can and this intent and untapped resource could be used for the good of all.

Let me know what I can do and I will.

OK enough said. For now, back to the EC.

Hi Otto,

how are you? Are you still working on your tube amp or is it already running?

I have finished to wind my 3stack unit and I hope I will get a chance to take it to my friend in R to test it as soon as possible.

I have wound all 3 CCs with equal mass and
again the feedback coils with equal mass as the 3 CCs.
So it will be interesting to investigate, whether this will have any positive effect or whether it is "just for the cat".


Bitte sag mal irgendwas, damit wir wissen, dass bei Dir alles ok ist.

Hello all,

@Gustav22

Im totally frustrated. Im looking for oridinary capacitors in picofarad at 400V or more. NO WAY to buy them here.
Then I found a company in Germany, they have the caps, asked if they would deliver me the caps, answer, no problem, I ordered them and now they dont want to send me the price!!! HA!! Thats nice. My friend wants also to build this oscillators....he is also f...d off....

This German company is selling also air capacitors like in the old radios. It seems that I have to buy old radios, if I can find them.

What youre doing is just fine but you forgot "dfros" post: HIGH VOLTAGE PULSES!!!

Im talking about another level of our work.
