Good day !
I have came across 2 videos and i want to share them with you .. probably is just "old news"

He is not using a "standard" grenade , The length of the wire is 56 m.
In the first video he is exciting the inductor with a signal generator, he found a frequency sweet spot where he gets "bubbles" on the output of the grenade, around 15.43kHz.
In the second video he has replaced the signal generator with the push-pull, yoke, series cap and he found again the "bubbles" in the system. But using the yoke that effect is dependent on the PSU voltage.
The grenade has no tesla coil connected, so this effect is not dependent on some pulser ..
I don't know who the guy is or what he accomplished.
I don't have access right now at the workbench, I want to ask if anyone have found the same bubble effect  on the grenade or on the inductor.

Itsu,

Thanks for the comments.
Improvement is always welcome,  so keep the comments going.

Yes,  thats the same version i have used.

To clarify the connection of the clamp i added a picture... i checked it double, but connecting it as in the circuit, the clamp will effect my gates and both FET's fire at same time.
So it cost me a couple of days trying to improve my push pull circuit ,......but at the end Lost_Bro suggested to reverse the clamp.
So i did and the results you have seen on my vid.

So its not my intention to say Verpies circuit is fault, but maybe or better there must be a explanation why i have a good clamp effect in reversed connection.



Also thanks for the S.A. protocol, again some usefull tips.
As i am analysing lots of grenades these days lately and see a lot of different resonance points in different sorts of grenade configurations.
Even the types which are not regular circulating on forums etc. have potential.


Greetings

Ape,

i am lost as to how you have connected your circuit now.
It looks to me you have +24V on the minus terminals of the big electrolytic caps, but that cannot be thru.
So perhaps you could modify the diagram as presented by Nick to show your new connections.
Otherwise good luck with this setup as it seems to do what it suppose to do.

Itsu,

The only change is the connection of the clamps.

   Itsu and All:
   Perhaps you can help me out, if possible. As I'm still having mayor problems with my set up, and I can't seen to find the cause. At one time you helped me with my Mazilli circuit overheating, and now I have a similar issue, but with the TL494/Tc4420 drivers.
   To explain how I have things connected:
   I have connected the positive rail of my 24, 10A PSU directly through the choke and then going to the center tap of the yoke. The primary coil of the yoke going out to the center pin of the three pin IRFP260P mosfet. And the negative rail of the PSU to the right pin of the mosfets. Is that correct? Or not?
   I have also connected the 1000k resistor as well as the facing 18v zener diodes between the left pin of the mosfet (gate) and the right pin of the mosfets.
   I also have the MUR1530 diodes going from the right pin of the fets to the center pin. This with the diodes facing me, as well as the fets.
   If needed I can post a close up of my driver circuits, or anything else on the device which may help. I just can't see what I've done wrong. But, this thing has gone haywire, (and me too) even without the yoke connections from the yoke primary to the fets disconnected, to see if the fets stay cool when I try this test, which they do stay stone cold.
  It must be something simple, but I've spent much time overlooking the cause of this frustrating situation.

  Verpies: Thanks for the correction as to the lossless clamp circuit. I may have to make one myself, If I can't get this fet overheating problem solved, before I pull the rest of my hair out. As it is acting like a short circuit, while yet, I can still light some bulbs. But, I have no output on my 3t coil circuit at this time.



  EDIT: Verpies, at one time I mentioned what I had read about the TC4420 mosfet drivers from their data sheet concerning their function of impeding the fets from being both on at the same time. You mentioned that their job was not that, but to add current to the fets, instead.
   Below is the description you posted from the lossless clamp, point #5:
   "Pins #6 of the UCC27511 drivers (U1 and U2) are used to ensure that two power MOSFETs (Q1 and Q2) are not conducting both at the same time. The voltage on pin #6 must be above 2.4V in order for the driver to be enabled (this happens only when the opposite MOSFET stops conducting. This is sensed by R6 and R8)".

   So, I ask you again, is that not the same function provided by the TC4420 fet drivers, besides providing additional current to the mosfets?
   And could this be why apecore's fets are now not firing at the same time, along with the lossless clamp, as they were previously.
   My fets are still both on at the same time, at times. Depending on the duty cycle, and frequency controller settings.
Varying the setting by only slightly on my device, can cause them to both fire at the same time, still.
