Hi Dog-One. How did you make out with your Nelson Rocha setup experiments?
Come across anything interesting?

P.S. There are likely many people out there who continue to plug away at the OU research,
but  more behind the scenes. I have been running a whole series of experiments in the
last many years, and continue to do so as time allows. I hope I am getting closer, but I
won't be able to say for sure that I have really got something concrete until I have a
working OU device sitting on my work table.  :D

Hi Dog-One. How did you make out with your Nelson Rocha setup experiments?
Come across anything interesting?

It is so far confirming everything Erfinder has been saying for the past ten years.

There's still something magical about electricity I'm unable yet to put my finger
on.  It's like some sort of spin or vortex that is hard to describe.  What I'm pretty
certain of at the moment is when you push current into a coil, it causes a magnetic
field to manifest.  This magnetic field seems to have inertia--it wants to persist
beyond when you cut off the current source.  This phenomena gives you the
advantage of interrupting the linear flow of time.  You in effect can borrow
this electrical energy and forestall repaying it indefinitely, each cycle, one at
a time.

More to come when I get to that next powerful milestone...


P.S.  Nelson amazes me how he is able to see all the moving parts and
keep things straight in his head.

Hi Dog-One. Interesting. Yeah, there are likely new mysteries to be discovered in
the subtleties of electrical and magnetic interactions if we can only wrap our head around
them when we run across them on the workbench. :)

Hi Itsu, guys:

I am bread boarding a TL494 PWM driver circuit this evening, and I am wondering if you left
the dead time at the default as I have done so far (which I think is maybe 5%), and if you think
having this much dead time between the outputs of the TL494 (Pins 9 and 10) will be detrimental
in any way, other than having a little less output? See the attached scope shot of the outputs on
pins 9 and 10 showing the default dead time.

   About 41% seams about right. You should be OK with the default settings, for now.
   Can your scope show the duty cycle readings?

Hi Nick. Yes, with the duty cycle pot set to max duty cycle it looks like
my dead time is about 7%, as the scope measures the duty cycle for
each output at 43%. Yeah, I would think that 43% should be good enough,
but I was curious if any of you guys were running at closer to 50% duty cycle.
See the duty cycle measurements in the attached scope shot.

   No. No one that I know of. But I wish that it could be run at 50%, or closer to it.
   Thanks for showing your duty cycle readings. Now I know where to set it up, to be able to see it showing the readings.

Hi Nick. I see. I did a bit more experimenting with it by applying some voltage to pin 4,
the dead time adjust pin, and it looks like I won't be able to get the dead time
any less than the 7% I have now. Applying voltage to pin 4 (0V to 3V) actually
increases the dead time even more. :) I just checked, and, according to the TL494 data sheet,
grounding pin 4 gives the maximum duty cycle, so it looks like 43% is about the best I can
get with a TL494.

If you ever have any questions on the Siglent scope, feel free to ask.
BTW, what model of Siglent scope do you have?

according to the data sheets like https://www.onsemi.com/pub/Collateral/TL494-D.PDF (page 6),

the TL494 has a deadtime control comparator with a fixed 120 mV input offset which limits the minimum output deadtime.

It limits the minimum output deadtime to approximately the first 4% of the sawtooth−cycle time.

This results in a maximum duty cycle on a given output of 96% with the output control grounded (singel ended operation), and 48% with it connected to the reference line
(push pull operation as we use it).

Additional deadtime may be imposed on the output by setting the deadtime−control input to a fixed voltage, ranging between 0 V to 3.3 V.

In my tests with TL494's, the max duty cycle in push pull mode is around 44 to 45%, but it differs.
When i decrease the duty cycle i have less output and / or more distortion on the MOSFETs drains, so i leave it at max. (45%) duty cycle.
If 50% would be even better i don't know as the TL494 won't go there, perhaps other PWM's can, but i doubt it.

Hi Itsu. Yes, thanks, that is what I had determined as well for push pull mode.
The best duty cycle I can get with my current setup is 43%. Maybe with some circuit
tweaking I could maybe get it to 45%. Anyway, 43% should be good enough. :)

   Void:
   The Siglent scope is the 1052DL.
   

   Itsu:  I have not been able to get the "effect" back with the snubbers on. So, I'm seeing what can be done about it, as the snubbers are needed, but then so is the effect.
   As it looks like some ringing is still needed. But, not too much ringing, and not too high a peak (under 230v, or so). So, I'm looking for a compromise on the snubbers.  As it looks like the snubber resistors, both the Oleg snubber resistor, as well as the RC resistors still get hot.  But they do help with keeping the fet's extreme overheating temps down. So, I'm working on all this now.

Hi Nick,

ok,  understood.
So for the effect to happen you need some level of avalanching in your MOSFET(s), so using a higher rated MOSFET (IRFP460) will not work either
as it will avalanche only at a higher (>500V) voltage peak.

This way, i think a selfrunner will not last long as the avalanching MOSFETs will pop eventually.

   That may be, but Ruslan, Akula, and other guys are getting their systems to work, so there must be a solution, without a meltdown of components from the Kaotic mode.
Perhaps a slight not too extreme avalanching is what is needed, with some ringing on the flat top of the square wave, as Stalker shows. Or possibly just being able to hit on the effect without avalanching the fet(s). I think that I showed that in my next to the last video. Where the Kacher is having an effect on the induction circuits, but not going into the total kaotic mode.
Otherwise the Kacher produces no effect on the induction circuits, and no additional light nor output is to be seen from their interaction when in the "normal" mode, at all. As most guys have seen.

   Watch Geo's 2 videos where he is replicating Urfa's way of doing it. You can see that at first video, there was no noise, but in the later Urfa replication video you can hear a very slight higher pitched ringing. So, he was getting the effect yet his fets were cool. And his device was very similar to mine, as least when he showed those videos using his simple kacher circuit.  His newer controllable Kacher circuit he has not shown running, yet.

Nick,

One big difference between your setup and Geo's is that Geo was using really big heat sinks on his mosfets. It might be worth changing yours to see if you can get the 'effect' and stay cool.

  Neither bigger heatsinks nor fans can keep up with the avalanche mode.
   I had big heatsinks on the Mazzili, FETs still got too hot while running 50% duty cycle.


  Maybe the avalanche is not needed to see the effect. That's what I'm looking into now.
 Ruslan's heatsinks and fans are no bigger than mine are. So...
