Nick,

Are the two halves of your primary winding in anti-phase?

See attached screenshot from Oleg. This is from his Youtube channel:

One thing to mention about this picture - the diode across variable resistor in the right almost defeats its purpose on changing charge time of capacitor. And because ol logical emenends have "AND"+"XOR" logic the purpose is a bit unknown for delaying already passed "ON" state with that capacitor before exiting last logic element. The another variable resistor+capacitor in the left gives same control. And also you can test logic in circuit simulation software such as Multisim.

Cheers!

Good day T-1000

Yes, I actually built the circuit (with-out the diode) see attached scope-shot: sorry for the blurry quality..........
Actually I was trying to nano-pulse SiC mosfets for another project, but the circuit does generate a variable ns pulse width.
This was only thrown together on a breadboard, so I do believe that the response / performance can be greatly improved over what I saw with my tests......

Take care, peace

EDIT:  forgot to mention that the output from Pin_10 is INVERTED logic, so  pin_10 must be connected to a Schmidt hex inverter.  The Hex Inverter output is the nano-second pulse width seen in the scope-shots below.

  Hoppy:
   I've always had ferrite pieces in my grenade former tube, as that's how I tune the frequency. But, I've never had this type of intense overheating. It's seams that the Mazilli driver is fine, but there may be something wrong with the 28 turns on the yoke. As everything is fine until I connect up that coil to the grenade. Then the system is heavily loaded, even without a load from the bulbs.
  As this is a new 24v yoke coils system. There may be something wrong there, like possibly wrong winding direction, maybe.
I wound the new yoke coils with the primary coil and 28 turns secondary coil, and the 3 turns coil (6 turns now), on this yoke ALL in a clockwise direction. But, my older 12v yoke coil was wound with the 3 turns coil opposite (CCW) the other two yoke coils which are CW.
  With of without ferrite tuning cores inside of the grenade, same thing, still the same amount of heat on the fets.
Actually, I have not been using the ferrite inside the grenade, at this time. So, it is not the cause of the heating.

Good day NickZ

Check for Cross-conduction (shoot-through) between your FETs.   If the drive signals overlap on the leading or trailing edges, that is a very bad sign............  even a small amount of X-conduction will overheat/burn up the fets very quickly, done there, been that.

take care, peace

Hi All.
Thanks lost_bro in response to the point "In regards to the  slow rising edge on the sg3525 generated waveform"
I was not sure why (and you're right on the lower frequencies)much better.

I do not know whether to use another driver change anything as the generator I have such a signal the measurement is no driver some are miserably looks
as you wrote that it can be cleaned! It even with this in their spare time after will prove quite interesting
I was wondering whether the finished system will not work the same:
http://www.ebay.com/itm/PWM-Generator-Controller-Adjustable-Frequency-100-400kHz-SG3525-Module-arduino-/121263675145
because sometimes the cost of the components of this consignment knocks on his feet

while it decreased cycle such a signal as below:
