NickZ,
Unconventional tech and operations it is :) .

(All) My snubbers do get warm but they can turn out to be very hot and even burn out the resistors, which
happend alot of time in trail. At some point when i experimented months ago, it blew the Caps of the snubber circuit.
But right now with the setting I currently have now, the resistors are warm but can be touched , Fets are cold to the touch.
I will be adding a additional circuit right be for the Fets able to control both fets timing and delay,
which will allow me to control them separately.
Next I will need to see what I can do to step up the output... it's uncharted waters again ;) . DC is next to see...
Distance of Antenna and Inductor (tesla-bifilar) made a big difference this time, since 28T was not used.


Void ,
The non dissipative snubber looks interesting, wonder if it would still allow the synchronization to follow up
if someone tries it out on there bench.

Hoppy,
 ;) alright

magpwr,
yes, High Freq & High amps. the mixture.
 ;) all is recorded. soon enough to show on scope what's happening.



                                 Cheerz~


   Geo:  If your snubber resistors are not getting too hot now, that's great. But, they may be part of the cause of you only being able to draw 5 amps from a 15 amp power supply. And only glowing the higher wattage bulbs at around 10% of their normal lumin levels. Much of your output may be going to the heating of those big bulbs, instead. And you have an upper limit of 24v times 5A, or 120w.
   Remember, that Ruslan, Akula, Stalker, and others, DO use heatsinks on their fets, (for a reason). So, their fets do most likely get too hot without using heatsinks. And so their snubbers may NOT be taking in all the overshoot voltages and spikes, but are letting the fets share some of the heating, as well. 
It a tricky balancing act, and almost impossible to figure without some trial and error experimentation involved, especially to get 4000w outputm such as what Ruslan is showing, while running the devices for several minutes, or hours without overheating. Even Ruslan had to turn off the device that he shown running in the field, or his rectifier diodes would go up in smoke. But, it ran a big load there, for a while.

  Hoppy: Well, there is only one way to find out if something works, or not, and that is to try it out.
  I am not yet at the point of adding a feed back path. I need to have my device working right, not overheating, and putting out a use able gain, first. I still can't run it for over a minute, due to these snubbers resistor or fets getting too hot. So, there is something that is NOT right with most all of the schematics, such as with Stalker's schematics. Which shows NO snubbers, at all.
I would have 350v peaks without any snubbers on, so those diagrams and circuits, just can't be the right way to go.
   
   There are still a lot of unknowns, one of them is the fact that no self runner has been shown outputting more than it's taking in.
Such as what you are suggesting that I do, or show. With or without the feed back loop.
But, I don't care too much about seeing comparative power readings, I care about self running, instead. That will be my proof.  I'll let you guys deal with input to output values, as you are the ones interested in such readings. Ultimately, that won't matter in any case. Only self running matters, for me at this time, not where the extra input is coming from, or just how to measure it.
Nick Z
Nick I have only one thing to say to you ! yes very well said and I wish you luck  ;D ;D PS yes the agenda is discovering a way of getting some thing to work, but you can't please every one ! good luck AG

Nick,

It may be that with some feedback, your mosfets will stay cooler but without feedback you may never keep them cool at the high bulb power rating you are after. All the schematics show feedback, so I dont understand why you dont build the complete circuit and then experiment on a suck it and see basis as you are now. If Stalker can really self run his device with no snubbers, then at least connect up the feedback components before declaring that there is something wrong with the schematics.

Hi Geo. I am not sure what you mean about the synchronization, but for waveform
timing purposes you can sync the tesla coil pulser to one of the outputs of the TL494,
which should be putting out a clean rectangular wave. Unless you mean something else?

Based on my testing, the non-dissipative snubber is a lot more efficient than the
RCD snubbers, and it stays nice and cool, so this is the snubber I am going with for
now to limit those big switching overshoot spikes. I posted my test info on the RCD
snubbers as well, with some suggestions on component choices to help avoid resistor overheating.

Basically I think people can go with 5 or 10 Watt ceramic block resistors if they are having
a problem with resistors burning in RCD snubbers. You can even put two 10 Watt resistors
in series to make up the total R value if you want to make sure your resistors don't burn. :)

The non-dissipative snubber doesn't have any heating problems at all that I have seen so far, so
it is worth considering IMO. I listed the component values I used in my testing to make it easy
for anyone else who wants to try it out.

I posted all my snubber test results and component suggestions for other people to make use of
if the info is useful for them. There may be other ways to go however. Based on my testing, RCD snubbers for
limiting the switching spikes are workable, but very inefficient.  At any rate, if you want your MOSFETs to be able
to last under steady running for long periods of time, then you probably have to limit those switching overshoot
spikes below Vds max or there is a good chance of eventual MOSFET failures.


Void nice artical,  but I cant make out what the diodes are as symbol is for shottkey diodes but could be zeners, I mention this as your sample scope shot still shows large voltage spikes.

Hi AlienGrey. Those are high speed diodes, not zener diodes. I used UF4007 diodes.
In my testing the non-dissipative snubber is taking the overshoot spikes down from about 240+V peak
down to about 120V peak, so it is working quite well. For my purposes the snubber only needs
to limit those spikes to a safe peak level below Vds max. I don't think a perfect rectangular
wave is necessary, at least not for my current purposes, so it seems to be a suitable choice. :)

All the best...

Even Ruslan had to turn off the device that he shown running in the field, or his rectifier diodes would go up in smoke. But, it ran a big load there, for a while.

Hi Nick,
Yes, because of having this specific area in tuning with the TL494 and after on Akula KAcher, is not allowing the heat to be nasty at all.
Yes, Higher input makes them warm or going hot, but it's true that there needs to be heatsinks.
Because, when I had things running on high lumins at output when the device was working lets say, the outside bench, some time ago,
having 1kw on bulb equive, low power, Fet's were warm and sometimes you'll get maybe one of them is working harder then the other.

Edit**
Yes, Ruslan could not in high loads not run some of his setups to long, some of his parts need massive cooling.

One of the example how to get the fets warm for no reason is when I start to de-tune the system
where it's not even in series resonance for the 3T cap anymore , or at some harmonic of the actual resonance point (a lesser ).
area. amps can shoot and maintain till 10 amps up. I can show that. or even be 6 amps. it's tricky tuning indeed.

For All :
What I can say about the tuning now is,
 the duty cycle is not really high and there is a reason why and this causes that there ain't no real heat on
the Fets yet. It will when output is greater and duty cycle also a bit more.
Managed to show the Effect happening at the output on low scale now on the inside bench,
without the 28T being connected is something new :), one thing I have to try out now is to rectify the output to DC and charge caps.
Ruslan/ Akula did this for sure, especially AKula, this was his method, only he used his 28T + from yoke to power input primary tesla.
for higher voltage inputs. still need to try that one out. 

The reason why the antenna is closer now to the grenade inductor is because it is easier to reach Antenna with the field generated
 by the inductor of grenade over the series cap action.
When to tune the field to sit in certain area with the antenna inside of it or lets say on the edge where Tesla topload  starts to funnel it in.
then you still need to see what freq for the Tesla coil for it to resonate with that field and that is where they start mixing up.
I tried to connect different taps on the secondary of the tesla coil, and it's just like tuning on radio stations to get it to happen.
found a few taps that worked, which are closer to the next harmonics of the first.
Again the right freq is needed for antenna top load resonate with the field of inductor.


Yesterday I did a test which I never had conducted yet but will upload this soon..
the results..Here is where it's crazy..
 ..and why this is important moment on the bench now,
The 3T/cap over inductor for series resonance is not really on it's highest peak for series resonance at all! :) here it get's interesting..
so to say, it's detuned for a reason.  So to say, it's in right condition to let it happen.
I won't be able to show not even a glow on a 25W bulb only with pushpull working on the output of the grenade! (Tesla disconnected)
But if you short the cap you see the sparks of generated amps but not to much.
Load comes alive only when Tesla is on as shown in previous recordings.
Tesla coil does faintly burn a filament of the 25W only when ground is connected.

Lets see what we see on the scope a bit further...;)

           Cheerz~

Hi Nick, I think Ruslan may have been using some of Allega's circuit designs, at least from
what I could gather from some people's comments at the time, and Allega showed
an RCD snubber to limit the big switching spikes in his schematic that was posted.

If other people are not using any snubbers then they may only be able run for shorter
periods of time without risking something burning out. It is possible to use just an RCD snubber
to limit the switching spikes and allow the ringing on the Drain waveforms as long as the
ringing is not going above Vds max, and you may be able to run the PWM driver under
heavy load for longer periods of time that way. Some people who have shown videos of
supposed self runners may only be able to run their devices for short periods of time
just to make a short video, and some people are using giant heat sinks with big fans
on them for their transistors, so they may be dealing with high heating on the transistors
that way.

All the schematics show feedback, so I dont understand why you dont build the complete circuit and then experiment on a suck it and see basis as you are now. If Stalker can really self run his device with no snubbers, then at least connect up the feedback components before declaring that there is something wrong with the schematics.

  Hoppy:
  Stalker has not shown any his newer devices self running. Nor has anyone else, lately, for that matter.
If Stalker can get his rigs to self run by using the posted schematics, he doesn't show it doing so.  I would guess, that I know why...  So, I take in all these different videos and schematics shown as current tests, and not as a done deals.


   I've already tried the feed back loop previously, but that did not drop the heating of the fets. Nor of any other components.
In any case I will connect up the loop, when I can. I only have a single 12v battery to replace the 24v PS that I'm now using for the input source. And I know that a 12v battery is all that's needed to kick start the thing up, but, it's not really enough to tune with, to get to it self running.   Just be patient, I'll show that loop, soon enough. I'm in no hurry, remember.

  Verpies said:  If you don't get the circuit working right in the first place, it will come back to bite you, later.
Or something like that...  and he was right.

I could have said 'supposed self runner', but that is redundant at this point.
No doubt everyone understands that any given video demo could be faked
or otherwise be misleading. ;)

  Void: Yes, that may be what we are actually seeing in those Ruslan/Akula type videos, as there are no heat readings being shown, nor are they showing it running non stop the whole while.

   I've disconnected the resistors on my RC snubbers, leaving only the snubber caps, and also the Olleg snubber running a 7500 ohm resistor on that snubber. So I now have them as I did in the last video showing the "effect" with no snubbers resistors on, that I posted. And as I feel that some ringing is also needed, because the RM sound and it's associated effect is in my opinion critical to showing any kind of OU results. Nice clean square wave signals, don't seam cut it. However, as my fets do get hotter now, I can't run the circuits for very long. Thus the dilema. 
   But, now I'm looking into tuning for the effect FIRST, then, afterward I'll further fine tune it to be able to sustain itself without component heating or over-voltage spikes. The most important thing for me, at least, is to be able to see some sync between the Kacher/grenade, for now, and be able to thus observe some kind of magnification effect. The feed back loop will be up, next.

Hi Nick, yes the approach that you and Geo are experimenting with seems to hold
some potential. Seems worth experimenting with for sure.  I think Geo said he is turning
the duty cycle on the PWM down to a lower duty cycle if I understood him correctly, so that
may be another way to get around the heating problem.

Yes, both should have been written as rhetorical questions as the answer to both is obvious; neither can be answered definitively.  ;)

  Yes, but turning down the duty cycle alters the wave form, distorting the ringing part, and lowering the output.
