Re Dally GNSI (generator nano-second impulses)

There IS such a thing as a nanosecond generator, litterally a pulse in nanoseconds, but it's not just A part, it's a system.  This works in not a few nano seconds but 10's to hundreds of nanoseconds, but is sub-microsecond.  Although there are writups that a similar choke/cap system can be used for sub-nanosecond UWB (ultra wide band) transmitters.. the DSRD is the final peice that makes the hundred-nanosecond pulse through the coil turn into a few nanoseconds.

The  74HC(T)00 pair is just an oscillator, like a TL494... but with a fixed narrow duty cycle and lower power requirement.

the first 74HC00 is a self osccilator with tunable freqency, and short duty cycle output.
The secon 74hc00 is a pulse chopper, it takes only the leading edge and outputs a pulse... as long as the input remains high it continues to be low.  This can be done with like a JK flip-flop also.

The third part is the transistor which is driven by a narrow pulse (several microseconds width).  WHen the transistor conducts, the energy in the capacitor near it is dumped through the toroid transformer.  Because there is a choke between that capacitor and the real 150V power storage, it takes a short time before it conducts... thereby starving the current through the toroid transformer and effecitively generating a much shorter pulse of output.

The oscillator part can just be another TL494.
A pulse chopper can be made using a pair of mosfets instead with a short RC constant between their turning on; but may not be required if the 494 is used with short duty cycle instead.

The tuning of the capacitor size and choke determine effective output.  The transistor/mosfet driver will be open for a longer time than the output generated through the toroid.

So through a system of parts a narrow pulse is truncated to just the leading edge of the pulse, and that is fed to a transistor, none of these actually work in nanoseconds but actually in microseconds.  What ends up generating a short pulse is a limited power supply with a blocking choke.  Once the transistor stops conducting, the 150V power supply recharges the supply cap at some time after as the choke allows it to conduct.

Clear as mud still?

DD2 is 'side 1' and DD1 is 'side 2' ... forgot to remove some labels.... reading from left to right is 1 and then 2.

Additional note; the cap used should have a low ESR so it can be filled quickly and get maximum current for the shortest time through the toroid transformer

Could this "special" mode be a case of spurious
oscillations?  Certain vacuum tube oscillators, and
now MOSFET oscillators too, are susceptible to such
operation if the grid/gate leads are positioned in
certain ways or the leads are too long and pick up
spurious excitation.

Apparently the modern terminology for this
condition is "parasitic oscillation."

Thanks SeaMonkey,

your thoughts are very much appreciated, i guess you are right, something is causing this parasitic oscillation.
It however seem to cause this parasitic oscillation only when using a ferrite (yoke) coil (high inductance) as with an air coil it produces nice stable sine waves.

Itsu,

Interesting waveforms from your latest experiment into the 'special' mode. Please show how you wound the primary of your yoke.

  Itsu.
  From what I see, your yoke is not wound as Akula has it, or Ruslan, or myself.
  I use about 5 or 6 turns on the primary, and about 20 turns on the secondary. Changing the windings count will affect the output.  Directly connecting my 110v bulbs to the yoke secondary coil output, lights up to 7 100 watt bulbs, with no low mode ever noticed, while the voltage/current levels are maintained.
  Ruslan is drawing about 12 amps while self running with no battery.

  IF the idea is to economize on the current draw, by providing lower current controls, or by higher yoke primary coil windings count, the output will be affected as well. As the yoke needs to have as high an output as possible, a high inductive voltage, and magnetic current levels, in order to obtain bright lights, and not just barely lit bulbs.
But, if the idea is to superimpose two different circuits output to heterodyne and improve the output levels, then this needs to be further looked into, to determine just how it all works. As without this surperimposition, all that we will have is an inverter circuit that draws lots of current, and will never self run.
 
   I'll view your last video now, to have a better idea of what you've just posted, as I just got home.

Correct, it is, as said in the video, the same yoke used as on my GeoFusion Roundcore replication.
The yoke was dressed up with many turns as specified by GeoFusion here:

where in he said:

"Primary has 27 winds of 2.5mm² Insulated wire  and secondary has around 35 winds of 1.5mm² insulated wire"


I just filled the yokes circumference with my primary to get a more even field which turned out to be 42 turns with a center tap at 21 turns.
