hi itsu,

This the nanopulse scope shot which i have attached is base on this video of Ruslan-
Ruslan Kulabuhov energy device open internals 2 of 2
http://www.youtube.com/watch?v=l_4sihIJYsE


Take note the nanopulse is superimpose onto 27khz.
Previously i can't determine if nanopulse(kv) is impose onto tesla coil frequency or 27khz from pwm generator.Now we know it's superimpose onto 27khz.

------------------------------------------------
Lastly recall the attachment which i have previously mentioned the PWM generator is actually  consist of SG3525AN,MC34063 to boost voltage to around 18.xx volts but definitely below 20volts base on maximum supply for the dual drivers TC4420 (6Amps) spec in datasheet.
(This attachment "Ruslan-PWM-Module" you got to magnify image to 200%...250% in order to see/verify the value on I/C faintly)
 

I have attached the final screenshot for today base on exact same pwm generator module being used in the above video-

It doesn't matter as the circuit we are analyzing is based on Akula circuit which based on TL494 for the PWM generator but the concept is still the same voltage boost needs needs to be applied for IGBT's driver.If using UCC37322P take note it's only 15volts.

Thanks Magpwr,

is this really all that is needed??   I personally doubt it.

hi itsu,

I have detect a flaw from the nanopulser section base on version 4.0.This is only realized after i connected to a Tesla coil from my old video.

You are right about the signal is inverted previously.
In version 4.0 fixed  the tesla coil won't even oscillate until i reroute the R21 to pin 8,10 on 74HC14 to get the inverted signal only then
tesla coil is able to oscillate freely.So instead of nano pulse pointing up i need to get pulse pointing downwards.

In other words i disregard the IRF540 and irf4905 section for the pull up since i just connect the pull up transistor 1.2kohms to 12volts supply this time.
But i am still using the bi-directional 18volts TVS diode for protection from output of IRF530.

I need to modify the nanopulser circuit in virtual or actual while retaining some of the nice feature which i like.

I have attached my screen shot from scope after rerouting R21 to pin 8,10 of 74HC14 instead of R11.

Please do advise me on any findings or suggestion which i might have overlooked.
 

--------------
I will try with other mosfet maybe transistor to see if i can get even more narrow pulse than produced by irf530.



 

Eventually you will all agree with this.

PS. Well, it is something i don't like with collector connection but i will cross check it when i'll be home.

Ps. I cross checked it. Collector has to be connected at the other end of the Tesla primary. (right side of PR.)

   Jeg:
   By reducing the yoke's primary coil turns from 12,12 to 6,6 and having the yoke secondary coil at 24 to 28 turns, it should result in a higher output at the yoke secondary. Then connecting this 24 to 28 turns yoke secondary to the 12,12 turn resonator air coil, you should be able to light several 100 watt bulbs, at least partially from the bigger output air coil. If not, the coil turns need to be further tuned.
 
  My new Mazilli crt is acting differently than my previous one. As I can't tune it by adding turning caps, or by adding magnetite magnets to the yoke core, as I could on my previous Mazilli circuit. Yet the yoke core has not been changed, it still has 6 turns on the primary, and 20 on the secondary.
  Without any tuning caps this new circuit can light 3 100 bulbs (partially), at the yoke's secondary coil. I have not connected the air coils to this crt yet. Previously I could light 5 100w bulbs at the yoke's secondary output. Also previously when using the older Mazilli, and adding the tuning cap on both the yoke's input side and the yoke's output side, I had not been able to obtain any improvement over the yoke's output, by the connection to the air coils. Including adding my Joule Ringer as the Kacher crt, nor with a simple Kacher crt, and using the regular Kacher type primary and secondary coils directly connected to the bigger air coil (output coil).  However I did not connect the 12,12 resonator coil to the bigger 48,48 24,24 output coil (without the last two 12,12 turns added) as is being shown now.
 The output was NOT as good previously (or the same as) from the air coils, as what the yoke can output by itself without the air coils.

  Reducing the yoke's input coils from 12,12, to 6,6 turn can also cause higher heating of the fets. Mine are still getting hot with 6,6 coil turns, after running for a minute or two.
  Ruslan is using the IRFP260N mosfets now. Not IGBT or the small fets.
 I am using this same fet but with a different snubber crt.

  "In respect of straight induction, the transfer efficiency will be very poor, so we are looking for a magical effect".

  Boy, I'd say...

hi everyone,

Base on this attachment nanopulser-27khz.

The only way i know in order to get similar waveform is to switch on tesla coil to fire at the peak of waveform eg:27khz which is already in sync with pwm generator via nanosecond generator.

The nanosecond generator virtual version 5 which i have cleaned up/modified as attached and i have actually tested this circuit  to a certain extend since i have no cable to assemble device/yoke it's holiday over here and on Monday.

I have clean up the nanosecond circuit to it's bare-bone and added TC4422 which can go as low as 30ns in datasheet.
The capacitor at 74HC00 is now reduced to 470pf from 1.5nf for the virtual and actual experiment which i got 50ns from output of TC4422 as attached from my scope  base on low pulse-width setting as set at 1kohms pot.
I can go little lower by selecting lower capacitor value.

If i am using positive instead of negative pulse for TC4422 i can easily turn on tesla coil via mosfet or igbt near peak or at peak of eg:27khz using the high dc voltage 100v....150volts as supply to fire tesla which would be in kv from the tesla coil.

The end result would resemble the Ruslan nanopulser-27khz screen shot.

In theory this seems like a most logical workable solution i can think of at the moment besides the 1st approach by superimposing eg:27khz signal to the base of 2SC5200 transistor which seems like a long-shot.

Fyi -Without nanopulser sorted out the assembled device would be as good as useless as well.
