Kapanadze Cousin - DALLY FREE ENERGY

[itsu]

I finally was able to  make a new nano-pulser to be used to replace the kacher.
Severall setups failed due to oscillations, but the present setup on a double sided PCB turns out to be stable.

To reach the needed 15KHz pulse repetition frequency i had to heavily cool the little toroid as it gets very hot expecially the primary wire (6 turns) on the inner side of the toroid.
I had to replace this primary once as it had melted the teflon insulation in 3 spots, see video.


With 250V on the drain of the 600V IGBT (50N6S2D) i get a 1.4KV pulse @ 10ns width, see screenshot.
The MOSFET driver is a IDXI414pi inverting driver running on 15V and directly soldered on the source lead of the IGBT.

The circuit to create the 250V and the 200ns input pulse are basically the "Oleg" red and blue box circuits.

Next will be to wind a 50 Ohm coax cable around the inductor/Grenade and sync the nano-pulses with the TL494 output.

Very fine Litz wire would help with wire overheating.
Evenly distributing the winding over the entire circumference of the toroid will eliminate localization of the heat buildup in the toroid's ferrite.

Larger toroid will help with the ferrite heating problem also, but too large toroid will prevent it from saturating which is essential for this type of DSRD driver.

That's 39kW of power for 10ns if you are measuring this voltage across a 50Ω resistive load.
The above should be a lesson to everyone how essential a good circuit layout is.

The frequency content of 10ns pulse with low pulse repetition frequency (PRF) will contain components from kHz to 100s of MHz.
This is Mr.Fourier, not noise !
Please keep it in mind that decreasing the PRF and/or narrowing the pulse width, increases the spectrum density and maximum frequency components.  This is very very important and somewhat counterintuitive because lower PRF leads to denser and higher frequency spectrum.  Please experiment with this Java Pulse Train Applet.

In fact you can trust your Spectrum Analyzer more than your scope when measuring the pulse width.  You should aim to obtain the densest spectrum and as high frequency components as possible. Seeing 500MHz components at low PRF suggests that your pulse is really much narrower than your scope indicates.

Of course do not connect the Spectrum Analyzer directly to the output of this nanopulser because you will damage the Analyzer - weak air coupling is enough.  39kW is no joke ...even for 10ns.

The MOSFET driver is a IDXI414pi inverting driver running on 15V and directly soldered on the source lead of the IGBT.

Wouldn't you get a better performance with a 600V MOSFET than 600V IGBT ?  MOSFETs are much faster than IGBTs although they they do have problems with R_{DS_ON} at higher voltages.
What is the peak voltage appearing between the drain-source of a MOSFET or between  the collector-emitter of the IGBT, anyway ?

Next will be to wind a 50 Ohm coax cable around the inductor/Grenade and sync the nano-pulses with the TL494 output.

Will it be opened, shorted or terminated at coax's characteristic impedance at the far end?

Anyway, AFAIR last time you did that, I think the nanopulses were detectable outside of the coax and I was surprised because they should've been confined to the coax's innards.


P.S.
Please remind us the schematic of your nanopulser ...with updated component values.

I believe Dally used shorted at the end, but I would seriously be curious what a properly terminated cable would do.  And what is the best way to do that?  Trying to recall the document you posted a while back, would you use a series resistor on the front side and another resister at the end?

Good evening Itsu

Fine job at that!!! 
I am very interested likewise to see the updated schematic for your -newest- version of this nano-pulser.
If it can be upgraded to pulse at a higher frequency this might also work for the *Chinese D.S. replication*.

take care, peace

Message for Itsu !

Your a good engineer clean tidy and professional and I enjoy your videos ! But I am confused as to what is driving you to do all there replications and not what I can fill is your real goal and to invent your own technology ?

Are you having trouble with free energy self running set ups or are you just happy doing replica builds ? I have never found one that can truly be built to a stranded that is presented in the drawings and data ..

There is a lot of negative and positive people here all are mostly just tinkering around or just pretending to know what they are doing but you have something very special you are real !

Please tel me what is it that you really want to build or discover .. I tend to go for 10kw and above and have isolated many effects known and unknown and I like to study quantum effects in EMF and the Doppler shift as a quantum field drive in zero point energy .

Micro circuits or nano pulse is some what on the small end of things and life is a lot easier on the larger side and quite often cheaper to ! Formula is the foundation and if it can not work there it wont work in the build. Experimentation with hard wear is time consuming and ohms law is nerve going to help with reactive circuits ! Try this try that approach is not formula and formula can be a language that you understand .

What is it that you want out of all this work ?
