    Itsu:
   Ok, I'll wind up the new yoke, connect it up and see if the output signals are more uniform, and I'll check the ringing as well.
  Since the two possibly still good fets have already been used, I'll use them again for this test, to see what happens.
I do have a 24v car bulb somewhere I think, if I didn't burn it up already.
  The new fets, and scope are not available, yet, until next week.  So, I'll do what I can until then.

   AG: Geo has not reported in for quite a while now. I don't know if he has been communicating with T-1000, or not.
        My inductor coil/3t coil circuit has had a very low output, and won't hardly even light a bulb, so I'll take a scope shot of that circuit's output when I get things better set up with the new yoke, new fets, and the Siglent scope.

Ag,

i had put up a screenshot of my 3 turn yoke coil output earlier in this thread, but it does not look pretty, see here:

http://overunity.com/12736/kapanadze-cousin-dally-free-energy/msg463422/#msg463422

Yellow is voltage across the 3 turn coil, green is the current through it and as we where at resonance, they kind of are in phase.

I don't think it was open circuit as that could have destroyed my MOSFETs, so normally i use only loaded conditions.

  Yet, we see on the Ruslan and others videos, that they turn on the device first (without the load), and afterward they turn on the load. Although that may not be the most recommended way of doing things, they must be doing it for a reason. I think it's because the full load won't light without first filling up the caps, and then it will light with the full load on. Otherwise they turn on one or two smaller bulbs, then the bigger bulbs. Otherwise it probably won't start with the full 1000-2000w load.

   Concerning the signal to the Kacher's base, I think that apecore is using the small torroid CT (current transformer) idea and taking the pulse from the inductor coil, throught the CT to the Kacher's circuit, and to Kacher's base. His Kacher is also frequency controlable. Maybe he can expound on how that has worked out for him.
   A current video of apecore's device working as he now has it would be good to see. When possible. As it sounds like it's working well. But, how well will it work when connect up to the feed-back path? Is my next question.

Nick,

You could also use 2 x 12V/50W auto bulbs in series.

PS haven't seen your yoke/toroid output wave form shot yet. ;(

Nick how does he do that, wouldn't you just need a gated oscillator and a drive circuit CD4046 ? some thing like TK produces by the score on his youtube channel assuming the FB pulse doesn't destroy it.

I never recorded the 4-turn output waveform on my setup, which was disassembled many moons ago.

    You'd have to ask apecore, as I am not very familiar with his current approach, and all it's details.
    Maybe he'll make a new video. Showing the interaction of the current transformer pulse onto his induction circuits.  From what I have seen of it,  it looked pretty interesting.

  That's also why we need to work together on all of this.

The problem with it being variable does tend to detune inductive circuits and the amplitude gain for the privilege.

  Itsu and All:
  So I've wound the new yoke, and installed it.  The fet ringing is slightly less but it's hard to tell because I'm running a 24v 18w car bulb on the yoke's input now. Both fets are ringing similar as they were before, maybe a little better, but I'd need to run on the PSU at 24v to really be able to compare.
   The 2nd image is the gate signals.
   The 3rd image is taken with the scope on volt/div on blank (50?), and the sec/div at 1us.
The expanded ringing scope shot is on .5us, and the same volts/div again on blank (50?). 
   Not sure what value is for the volt/div at the blank setting, so I figure that it's possibly at 50.
   Here's some pics, let me know what else you may need to figure the snubber values.

Nick,

looking better,

If the expanded ringing was with 0.5us setting, then the tops of the first 2 peaks are slightly longer then 1 division, so i made it 0.505us, see screenshot below.
This means 1.98Mhz ringing frequency (http://www.calctool.org/CALC/other/converters/freq)

Now follow the step 2 of this procedure:  https://www.maximintegrated.com/en/app-notes/index.mvp/id/3835   meaning you have to add a shunt capacitor
across the drain to ground to reduce the resonant frequency to approximately half or 990Khz (means a time of 1.01us between the first 2 peaks).
Use a good quality ceramic or film capacitor able to handle the peak voltage you see on your scope.

When you have found the correct cap value, take another screenshot of the drains (expanded) and show it, then we can continue with step 3 (Calculate the parasitic inductance).
   
Did you tune the TL494 for resonance of the wima cap / inductor?  What frequency was this resonance frequency?


Thanks Itsu

  Itsu:
  I believe that the 3 division gate signal in the image that I posted was running at 16.7KHz.

  I've been looking to see what caps I have that might work for the snubbers.
But, it's been hard to find a matching pare of the right ones. Like a couple of 222, or so.
I'll continue looking tomorrow for some caps. Otherwise I'll have to order some, which can take a while.
  One question, when you say that the caps should go between the drain and the ground. Is that the same as between the drain and source? Same thing?

   I was looking at some of your Ruslan replication videos, and could see that you had a bit of a hard time with those "nasty spikes" also. Seams like most everyone has. But, you were able to tame them, it seams.
 
   If I touch the fet heatsink with my hand and with bare feet, I can reduce the spikes on the ringing signal by about 25%.  So, I'll be looking some more into the groundings, and such also. Looks like the proper earth grounding is very important for the TL494 board systems. Which seams to help a lot with reducing those spikes. There must be a way to keep the spike downs even without the snubbers, as Stalker doesn't use snubbers, and he's been at this for a while now, also. But maybe he should.
Akula and Ruslan used snubbers, on their fets.
   Anyway, I'll install some caps tomorrow and see what happens.

Nick, the Source pins of the mosfets are connected to the circuit common negative aka "ground", right?

And the body tabs of the mosfets are internally connected to the Drains. So when you touch your heatsinks, and you have bare feet, you are providing a "snubber" capacitive-resistive connection from Drain to Ground through your own body.

At this point I am unsure of the exact circuit you are using, so it might be good if you could provide it again.


By the way, your focus problem on your scope is almost certainly due to one or more bad resistors in the Focus control's voltage divider, made of a string of 5 or six 1/2 watt resistors of 510k on the main board, resistors R888, R889, R890, R891, R892 and possibly the 75k 1/4 watt R894. These are all grouped together in one place on the board. This is a very easy fix as these things go.

Nick,

my question is if you are running your setup with the wima cap / inductor in resonance as that has a big influence on the spikes / ringing.


Anyway, yes i meant that the snubber test cap should go between drain and source (= ground).

Good point from TK, if your MOSFETs are not isolated from the heatsinks, touching the heatsinks will cause you to be a snubber!

With your 2Mhz ringing signal i guesstimate you should need a test cap of around 1.5nF to half it to 1Mhz
