@Magpwr: How do you call something a "nanosecond pulser" when it produces a pulse width that is over 40 MICROseconds wide?

Can you show us the rise time of a single pulse with your system? Does it produce a pulse risetime of below 10 nanoseconds?

hi TinselKoala,

The previously attached nanosecond circuit of Oleg for Ruslan was orignally design to produce a "single narrow pulse" in the nanosecond range.
It does nothing base on my experiement even with a high voltage >1kv in the <10ns range.

So what sergey have done is merely tweak the capacitor value and add sk diode in Oleg circuit to produce a wider pulse in the microsecond range example 7us to 40us like mention depending on what capacitor value was used.

Sergey circuit is a interrupter operating at approx 1Mhz to 2Mhz but the pulse width needs to be in the nanosecond range 88ns....250ns depending on the mosfet and voltage applied 12volt....250volts dc.
Got to strike a balance.That is why there is a sk diode or 1n4148 used in order to create a narrow pulse in the nanoseconds range.Anything which is under 1 microsecond...

The rise time is not even applicable for kacher,it's the pulse width, high voltage and the position of interrupted pulse which is important.

Like said the components like capacitor in Oleg need to be tweaked which can be discovered easily through experiment.

The mosfet driver i am using can handle easily up to around 2Mhz.


I am unable to explain how i achieve high frequency output using low frequency since there is no actual cavitation involved.I just consider myself an unofficial "reverse engineer"

Good Luck to the rest as i need to do other research as well.24hr is really too short for me in a given day and it's late night over here.

----------------------------------

TinselKoala please check my youtube for my high frequency high voltage generator which can provide <10ns pulse up to 2Mhz.
But i will not give away my 6kv version.     The above is just a appetizer.bye.

Yes, and also put some desoldering braid and a flux pen on the list. And do try to get a few genuine Texas Instruments manufactured TL494s, there are a lot of fakes and poor performers out there.

   All good advice.  Will do.

   Yesterday I almost finished the snubbers, but I had a delay, as I broke a pin off one of the tiny driver chip when handling the board.
Bummer, as it wasn't easy to replace. But, it's been replaced, and I'll try to finish up the whole board today. I hope.

   I learned my lesson and will order the IC sockets, and the bigger through hole TC4420 driver chip, as I was sent the TC4420EOA.
I'll try to order the Texas Instruments TL494, as well, but next time, as I still have several of them.

@mgpwr: OK< ty.

The high-frequency output from secondary, using LF input from primary, is probably due to resonant ringing, and to get this to work properly the secondary must be loosely coupled magnetically to the primary. This is how Tesla achieved HF outputs from his LF spark-gap-interrupted primary supply. The idea is this: the primary drive circuit produces a fast risetime and falltime short pulse at a relatively low frequency. This causes the secondary to ring at its higher frequency of 1/4-wave resonance and allows VRSWR (voltage rise due to standing wave resonance). Like striking a bell with a hammer. A single strike produces a lot of vibration cycles in the bell. If the primary is too closely coupled to the secondary this causes the secondary to induce back into the primary and damps the resonant rise. If the secondary and its associated capacitance are carefully built for "high Q" then there is little or no decay of the secondary ringing, until the next LF pulse comes along from the primary.
But this is different from the way modern solid-state TCs work, where the primary is pulsed at the same HF rate as the resonant frequency of the secondary. So you get a primary pulse and a secondary sinus cycle, just one, and then another primary pulse comes along. In this setup the primary can be much more closely coupled to the secondary since you aren't worried about mutual damping.
I think the circuits you are working with are trying to do the first, older Tesla method of pulsing primary at a relatively low frequency with short pulses of fast rise and fall times, and allowing the secondary to ring freely at its higher quarterwave resonant frequency. So you might try actually reducing the electromagnetic coupling constant "k" between primary and secondary. Also think about "Q" of the secondary and try to maximize that with careful construction and low-loss components after the secondary output.

Just my "two cents worth" based on my experience with TCs and SSTCs and drive circuitry. Good luck!

Mr Tinsel Hi and thank you very much for that explanation as the 'dam thing' Tesla coil in the katcher circuit has been doing my head in, so to speak as I would have expected a much longer wind and lower frequency after seeing H Morays 'winds on his device', ect, So how would you suggest one would be the correct way to sort out this problem, as we would be very interested in any advanced problem-solving in this device you could come up with.
