Kapanadze Cousin - DALLY FREE ENERGY

[Hoppy]

Before affirm something you need fisrt to know what are affirm and second to check your affirmation before present it to public. What are you know about Dally's pulsing the coax with nano pulses? You don't know nothing about it. Dally gave schematics, photos, recorded 3 videos and many people who even haven't hold soldering gun not mention soldering station affirm Dally's device is a fake and videos were hoax. On that way you can affirm Tesla didn't exist at all and all his discoveries and inventions are pure fiction or somebody else did all of that.
ABSURD. No one knowledge can be ABSOLUTELY RIGHT !! Everything must be checked and verified!! This is universla rule and must be implemented in all fields of human mind activities. Why ??
Because it's the only way which can bring all of us new and safe future not end of civilization like ILLUMINATI CABAL plan to do !!

Differences of the commercial high power diodes from ideal ones lead to efficiency decreasing and pulse shape distortion. These defects can be eliminated by carrying out the following conditions: a) forward current duration and brought into the p-n junction charge have to be as small as possible, and b) reverse current duration has to be considerably less (10
times and more) than forward current duration (Belkin et al., 1992). Earlier DSRD (Zienko, 1984; Grekhov et al., 1986; Kardo-Sysoev and Chashnikov, 1986) are used as a sharpener of
the step voltage generated by power semiconductor switchers (high power thyristor, for example).

With respect, I'm not affirming (to declare positively or firmly; maintain to be true) anything just giving my opinion which everyone else does on forums, rightly or wrongly!

Would SiC diodes with negligible reverse recovery times meet this criteria? These new schottky diodes are expensive but now available in ratings up to around 20A @ 600V.

I'm able to hold at around 50V on pulse and I doubt that Dally did much better.

Do you realize that a 50V pulse on the collector of Q5 (e.g. KT926) can still provide 1kV nanopulse at the DSR Diode when it abruptly stops conducting in reverse?
If not, see here.

Hold your horses!
Hoppy expressed his doubts in an acceptable manner. He gave logical arguments citing his experimental results. He cannot be faulted for it. He realizes that T1 cannot provide enough energy to sustain Dally's circuit if that transformer works as an ordinary trasformer, but please notice that he does not affirm that Dally's system does not work or cannot work.
If you read between his lines - he allows for the possibility that T1 might not behave conventionally and something not ordinary might happen in it due to these nanopulses.

Certainly, Hoppy does not assert anything that he hasn't veried.
Everyone has the right to have doubts.

Shottky diodes do not work well as DSR Diodes, because they do not have semiconductor to semiconductor junctions, instead they have metal to semiconductor junctions and those junctions have very sharp borders.
DSR Diodes require semiconductor-semiconductor junctions (PN or PIN)

SiC semiconductor-semiconductor diodes (PN or PIN) could work if they were manufactured differently (more diffused), but I do not know of any that exhibit the DSR effect. There was a guy that manufactured his own experimental SiC DSR Diodes on purpose, but they were not Shottky diodes - the were diffussed PN junctions AFAIR.  I can dig up his name if you want.

The ideal DSR diode structure is similar to a PIN diode that has blurred border between the P-I junction and between I-N. 
In other words, for best DSR effect,  the semiconductor junctions have to be diffused (not sharp).

It so happens that the old high power silicon rectifiers were poorly made which resulted in blurred border between their semiconductor junctions and now they unintentionally work well as DSRDs.

The are very few DSR Diodes available that were tailored for this effect purposely - all of them are custom experimental devices.

P.S.
DSR Diodes must be able to conduct very high current in reverse for apx. 20-70ns - that's the essence of the DSR effect !

Is that approximately right?
so a 220 uh coil, I have that, it's 13turns x 5layers x 6cm or something, and it measures 250.  but it doesn't have a core.  The schematic indicates a solid core, would probably be better, ya?

I do not understand how this saturable core transformer circuit works.

The article, that explains the operation of this DSRD driver with saturable core transformer, is in Russian language.
You will have to ask Сергей or Vasiliy to explain how it works, based on that Russian article.

I have never succeeded in getting any saturable core transformer DSRD driver to work.
I only had success with this transformerless DSRD driver.

P.S.
Adding a ferrite core to an inductor increases its inductance but decreases its speed because ferrite introduces a lag.
