hi Bat1Robin2,

I have just read your post which contain the attachment which you have drawn a red line to input of IR2184 after the inverter gate.

You seem able to read and understand the circuit which makes it little easy for me to communicate with.
This way we are able to select if we want the nanosecond pulse to appear at top half or bottom half of sinewave across 0.47uf capacitor.

Do ignore other pll/non pll based circuits found where nanosecond generator is getting it's signal from dual channel output leading to the dual igbt's driver for yoke.
Reason being the nanosecond pulse will never be aligned at the very top or bottom of sinewave taken across 0.47uf capacitor base on my previous experiment.

-----------------------------------------------------------------------
There is something else which i have overlooked apart from the recent discovery that a current transfer to Earth is one of the most requirement as indirectly revealed by Tariel,Vasmus,Ruslan and Akula using clamp meter as found in video.

Latest discovery-
If you take a look at the circuit which you have edited.There is a capacitor of unknown value which is connected across 28 turns output from yoke core.
This was not implemented in any of our replication device yet.

I then recall in the old Akula circuit diagram there is a capacitor which was connected in the bifilar winding which i have attached and circle in red for reference.
I only got time to resume experiment and etc from Thursday to Sunday.
-----------------------------------------------------------------------
I have attached the Akula tesla coil tuning pdf which was typed by MenofFather in Russian base on Akula's video on harmonics,current to Earth.Also take note simple explanation from Akula on whywe should not go below 18khz for a air core multilayer transformer .
English google translated version is found bottom half of pdf.

The above translation is obtained from copy of old Akula video which was deleted-

Other small tips for the Yoke driver-placing ferrite beads on both gates of  igbts would produce nice square wave without even seeing any ringing ripples at all.
I am using just 1 amorphous beads but common ferrite beads can be used maybe 2 is needed at the gates if you are particular about having nice waveform while in operation.
But take note igbt's like to be driven at 18volts which near the limits of TC4452 at 15volts is fine but igbt will heat up easily even with cooling fan if power exceed 100watts.

I am using FGA25N120ANTD -1200 V, 25 A NPT Trench IGBT  for yoke\toroid driver although the commercial 1800watt 240volts induction heater i own merely using the 11Amp version.
Another good  IGBT which produce even lower heat at 15volts for gate signal is the 50N6S2  600volts igbt this is without inbuilt protection diode version.

Dear Magpwr.

Ah, that brings back some memories !!

I used various coils within the main coil. The capacitor was formed using 2 concentric Aluminium slotted tubes with an A3 size lamination pouch as the dielectric. I was consistently raising 10 Kv at around 84 KHz ( fixed ) no mater what the primary drive frequency was set to.

I must have toasted at least 4 pairs of IGBT's but never took the device any further. Other projects are underway so I wish you all the very best in your endeavours !!

Cheers Grum.

hi Grumage,

May i ask if you can recall at which point in your circuit was the measurement taken in order to see around 10kv @84khz."I am really curious on how to obtain 10KV without using a tesla coil"
Whom knows this high voltage might be what i need.

It seems plastic sheet used in lamination is able to handle 10kv base on a HV capacitor creation video.

The only thing i can visualize is the HV capacitor which you have created using 2 aluminum sheet which is separated by plastic lamination sheet and this is connected in parallel with the center coil in order to
form the L/C tank which the resonance frequency is fixed.

I got 3 high voltage probes 40kv 20Mhz,15KV 50Mhz and a 40KV multimeter probe which was delivered to me by accident.

Dear magpwr.

I used a 10 turn pickup coil made from 3 mm dia insulation around a 0.5 mm conductor wound at the base of what was around 650 turns, 32 SWG Tesla type coil.

My video thumbprint shows a wonderful picture of the signal, lower trace, all those interference patterns!!

T-1000 and I worked out that the voltage was around 10 Kv from the ratio's. Oh, and another tell tail, I had plenty of Ozone being generated!!

The internal coil ended up collapsing, I had wound it on a thin plastic former and I assume that the induction effect had warmed up the Copper coil, shrinking the former in the process. I was able to heat up a 25 mm dia Steel rod to the point of not being able to hold it within a minute or so.

The device also interfered with my video camera, first take, everything froze, second take, I managed to shoot the one posted but if you noticed the last 20 to 30 seconds the video is frozen but the audio continues!!

Cheers Grum.

  Grum:
  Good to see you're posting back here once again. I hope that you can join us, on some replications, when you have a chance.
 
   Geo is now thinking of building something like what we were working on before, that is, the Akula first self running device.
Same device that we were trying to get working previously. 
 
  I'm still trying to tune my second video Akula device replication, (my current version of it), and trying to find the illusive magic frequencies.

   Geo: I was asking previously HOW Akula tuned his circuit to produce the result we could see on the scope in the video that you posted.  What exactly does he do to tune the running frequencies, to produce those results?
