Hi Itsu. I have never played around with snubber circuits, but a couple of the Akula schematics
showed either  2.2nF or 10nF in series with 7 ohms. If you have any 2W carbon resistors in the
range of 10 to 100 ohms, you could maybe try that to see if it makes an improvement or not.
All the best...

I changed from a 9nF in series with a 120KOhm resistor from each drain to source (obviously not working) to:

# a 2.2nF in series with a 10 Ohm resistor and a UF4007 diode parallel to this resistor (cathode to ground, so different from the Ruslan diagram)
# a IDH12SG60C schottky diode from each drain to ground (cathode to drain)
# a 140V varistor across each drain / source.

But the oscillations, ringing and irregular switching has not improved on.

So looking to other reasons why this snubber is not working properly.



Nick, i am not so far as to test with the kacher, and i am not convinced that more higher wattage bulbs will be better.

IMO, if this yoke is not going to be switched properly then no progress is possible.

Just to be complete, i did change in the nano-pulse part from 7400/7414 to 74HCT00/74HC14, this greatly improved the switching signals
so Magpwr was correct there, allthough it did work with the older ones.

Regards Itsu

On a positive note, despite the chaotic behaviour at the MOSFET's drain signal (did we ever see a scopeshot of Ruslan there??), the signal
on the L3 coil looks promising and is peaking around 27KHz in resonance (with the oscillations/ringing visible ontop), see screenshot:
(no kacher or nano-pulse active!)

  Here is a video of my latest Mazilli/yoke core build. It's just the induction heater crt part of the Akula/Ruslan type circuit set up. The big air coils and Kacher crt will be added soon, but I wanted to show what just the yoke will do by itself.
It's running for now on a 12v, 10amp battery charger, which may be providing 10 amps (or less) drawn from the device.
NOTE: The output voltage and amperage at the bulbs can't be read accurately by my analog meter.
  This is to compare notes with what you guys are observing at this point.

Ok, that's interesting. Unfortunately I haven't built my TL494 driver circuit yet so I can't
compare notes on that. If you have a resistor around 200 ohms, you could maybe try
in series with the 9 nF from drain to source, with and without the diode across the resistor, and see if there is
any improvement at all. I haven't tried it, but I am thinking that may possibly make at least some improvement.
Has to do with where the cutoff frequency is. Not sure it will make a difference however.
All the best...

Ruslan has a new video out showing more about his new device he is building that will
run on 24 volts, which Ruslan is saying should be better (presumably more output power capability).
He showed his new driver boards in the video and I have drawn a red rectangle around one of the circuit boards
in the attached photo. Any idea what the board might be for that I have highlighted in the red rectangle?
I am thinking it may be a controller board for syncing/pulsing the kacher driver? Any thoughts on this?
All the best...

hi Void,

Thanks for showing me the section of the nano pulser .At least now i know he is also using the same thing. :)

The 8 pin is TC422 after i spotted the brand on I/C.It is the buffer/driver from 74HCXX I/C.
This TC4422(30ns) later version i will be boosting with MC34063 to get to around 18volts(Max) to properly pulse ultra fast IGBT's which spec would mentioned <30ns or <50ns delay.  :D
For experiment i am already using 12volts supply for TC4422 but this needs to be improved later on.

Don't you think it's similar to my current nanopulser version 6.0 which i have already present in virtual many times using TC4420(6Amp)\TC4422 driver(9Amps) base on last few posting.
But check which one got lower ns delay and use that.
I just realized forgot to change the schottky diode in virtual with all 1N4148 in ver 6.0 that's all.1N4148 is faster for signal.

Take note i am using only 1 output from PWM/signal generator as well as presented in virtual ver 6.

hi itsu,

Are you using IGBT driver eg:TC4420 (Eventually need to be using MC34063 boost voltage to 18volts) or etc to buffer PWM I/C:TL494.Recall the screenshot of PWM geneator.

It is not advisable to connect TL494 directly to mosfet or igbt even via a <10ohms resistor.
Hence IGBT driver is needed.Recall the screenshot which i mentioned TC4420.

Since i have previously bought TC4422(9Amps version,overkill for this task)i got to use this instead of TC4420.

Base on delay shown in datasheet TC4420 is a better choice.

I am using 1N4148 in nanosecond generator instead of schottky diode for my actual experiment.

I still think connecting nanosecond generator directly to pwm i/c output is a better choice since it's less likely to pick up noise from gates of igbt with yoke.

that's good to see... that's the same curve I was trying to show that it's without the nano pulser... (other than your current driver looks really good for driving sharp changes incurrent)
the higher frequency there should be the L(?)... grenade coil frequency.

Hi Magpwr. Good detective work on that circuit board. It looks like you are right.
Yes, it is interesting that your pulse control circuit is very similar to Ruslan's.
Is that version 6 schematic of yours complete now? It looks like that may be the way to go... :)
All the best...

hi Void,

The circuit board portion is completed.
For the the input signal you can cater for additional signal input using 270ohms and a another 1n4148 diode like Ruslan did.
But i find the voltage TC4420 located on nanopulser on Ruslan was not boosted by MC34063 circuit to around 18volts so that it can properly drive IGBT .

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

This is the latest findings.I find it strange that TC4422 perform better than TC4420 base on the peak pulse it can produce using 12volts supply in virtual.
Since i only got TC4422 which is being used in current experiment.

Take note I get better result using G4BC10UD (600Volt IGBT) than IRF540 in actual experiment if i supply TC4422 with 12volts.But this needs to be driven with 15...18volts later stage.
There is limitation in virtual that i can't change voltage for virtual TC4422.Hence for virtual screenshot i am using only IRF540.


-------------------------------
Nano pulser Circuit driver portion is final at version 6.1 as attached without mosfet or transformer
But Interface to device is not sorted out yet.

Transformer is tricky and i can't advise.Latest i am using small toroid to get this nice pulse as attached but i am supplying 400volts from my variable dc hv generator.

No heating on G4BC10UD detected.

Lastly HV probe for scope is needed around 10KV to be on the safe side. :D :D :D

Great work Magpwr, and thanks for posting the current version of your nanopulser driver circuit.
I am going to have to order some parts to give it a try. :)

hi everyone,

I have attached the nanopulser final update version 6.2.
Please use this version.D4-IN4148 was not added into virtual previously.

Please ignore all the previous version of nanopulser which i shall no longer discuss about it.


Please use attached screenshot of TC4422  which is taken at 50ns/div setting at 10volt/div.TC4422 is powered by 18volts from boost circuit without connecting it's output to anything.
Please use this waveform as reference only.

Magpwr,

i still follow the original Ruslan diagram, which used ucc37321 MOSFET drivers, however as i only had the non-inverted ucc37322 i am using those.     
MOSFET's used are IRFP260N's.

I have (or there is) a basic problem to drive the 2x 6 turns primary of the yoke, as it is very hard to tame, you will find out.
As i never have seen any screenshot of Ruslan or Akula of the drains of the MOSFET's, i assume they have the same problem.

Regards Itsu
