Itsu: OK, I forgot about the rectifiers at the output on Geo' setup. :)


Hoppy: That's the thing. We do know for the most part what Ruslan's configuration was. 
In that old video he just had a PWM driver and a non pulsed kacher and the grenade. It is
only some specific details on tuning or similar which he left out. The overall configuration
we did know.

Void,

I accept that the build setup looked reasonably clear to you visually but this is not enough IMO when the exact circuit configuration is unknown.

Well that's interesting, Because I would like to know where Ruslans circuits actually are and where they have been published, All I can find are his videos and a few bits of info he has shown a Katcher construction but his documentation he says he has never published, unless you know different of course then please let us see them as they might be very interesting, Akula and Sergey yes and many others too, I would be reasonably cautious before building some thing and expecting it to perform.

Hi Hoppy. Ok on that. I know what you mean.
I will continue my testing in search of the elusive OU effect... :)

Geo's 120V (AC/DC) grinder runs on DC from the rectified grenade output, probably on a quarter or less of its needed power.
No mystery there IMO.

Radio Moscow stopped transmitting when the Sovjet Union collapses, it continued as "The Voice of Russia", but
since 2014 this also stopped transmitting on short wave, see wiki https://en.wikipedia.org/wiki/Voice_of_Russia
So what do you hear Nick, and where does the sound comes from, the yoke or the coils or what?

   Itsu:
   Thanks for the info on Radio Moscow.
   No wonder all I get when I tune into Radio Moscow is Static.

  What I hear and see is the exact same thing that Geo is showing on some of his videos, as the " effect".
  Yet, his FETs stay cool, but his inductor coil heats up.  Like yours did.
His inductor is shorter than mine is. He is running the 10 meter size, and I'using the 18 meter inductor. Maybe why it heats up more.

  As my peaks are going over 200 volts I can't turn on the device for more than a few seconds without heating the one fet up. But, I can show what it sounds and looks like, soon. Maybe tomorrow, as I'm still working on all this.
 
   Looks like I can drop the peaks by placing a cap in certain places on the connections of the rectifier. Still looking into this.

Nick,

Will you be adding the feedback loop now that you have the 'effect'?

Coils heating up could be a sign that they run just under or just over resonance

Yeah! it's because the inductor is not the exact wave length. Verrrrrrrrrry good ;)

Nick,


ok, so no real Radio Moscow, silly me.


My inductor heats up fast when in resonance, its half the length (18m) of the Grenade (36m).

I (we?) tune for resonance on the inductor which when in (series) resonance has minimum impedance (basically only the resistance of its wire) thus maximum amperage
therfor running hot.

Series resonance:   http://hyperphysics.phy-astr.gsu.edu/hbase/electric/serres.html

So not sure how to interpret both Belfior's and AlienGrey's comments.

Yes, there is maximum current in the series loop at the resonance frequency. Resistance
of the wire at a very high current causes the wire to heat up. Smaller gauge wire will heat
up more than larger gauge wire since its resistance will be higher for a given length. 
Using larger gauge wire will allow for even more current to flow.

Belfior: No, tuning off the resonance frequency will not cause more heating.
It will cause less heating because the resulting non-cancelled reactance will
reduce the current, which means less heating in the resistance of the wires.
Reactance itself does not cause heating. Only resistance causes heating.
The more the current, the more the heating in the wires, which is so-called
"I squared R" (I^2 x R) losses.

The over heating problem.

If we cast our minds back a year or two I and a few others also mentioned over heating to an extent to melt the PVC tube, with only small loads, I think we later found the circuit made a good RF crucible heating furnace ;).

If I recall T1000 mentioned there could be a problem with some so called copper wire Iike cheap electrical trunking cable with impurities like iron and oxygen used in its manufacture.

It is possible to obtain wire used in the Audio industry which is claimed to be pure copper, however, this type of cable is 4 or 5 times dearer than fine multi strand cabinet wire battery cable.

However Copper or Aluminium is still metal.

Any one fancy winding a layered copper tube version?

   As I look for the cause of the kaotic mode, I find that it happens only when the one mosfet goes into saturation, at 200 volts or above that voltage. Below that there is only little heating of that fet. The other fet has lower peaks and does not go into the same kaotic mode at the same time, or as easily.
  On the other hand, the TL494 and driver circuits are working great now. No problem, or glitches there.

   I had made a video last night, showing the effect, but the profile setting was on my camara so the video looks wrong, like sideways, so I didn't uploaded to youtube. I'll try to make a better video later tonight. But my camera turns off if I get too close to the HV.
  The main thing right now is still to get these snubbers working properly, or I'll keep blowing more FETs.  I have to get the peaks to 200v but not above that point. Or the effect won't happen. As it won't kick into that kaotic mode, at lower voltages.
And, Hoppy from what I can see so far, it's in that special kaotic mode where the magic is to be found. And which is caused by the Kacher's interaction, and not just a failing Fet..

This is an interesting observation in that if we assume that the 'hot' mosfet has avalanched, then it is in effect acting as a zener diode and conducting a high current whilst clamping the voltage at level governed by the heat level of the mosfet die. If this condition is critical for the 'effect' to occur, then it suggests that a constant or pulsed DC bias current is needed in the yoke primary winding. Another thought is whether a pulsed avalanche condition is feeding very sharp unipolar pulses into the yoke primary winding, a condition created by Tesla with his spark gapped devices.

I think you need to go back a bit, try disengaging the Katcher and loading the grenade output with a small build 40w something like that and monitoring the waveform from the yoke output with a winding of a toroid or direct and monitoring the two drain wave forms, you could video them. But you need to see whats going on with your setup.

Found this PDF:  http://www.semtech.com/images/datasheet/transient_voltage_protection_of_mosfets.pdf

It gives some usefull info on how to protect a MOSFET drain and gate by using a TVS.

Guess for our setup (IRFP260 = 200V) we can use STMICROELECTRONICS SM15T82AY DIODEs.
It has a working Voltage (Vrwm) of 70V  (max in our case would be 2x 24 =  48V)
and a clamping voltage of 146V which is way below the 200V


•  Breakdown Voltage Max:   86V 
•  Breakdown Voltage Min:   77.8V 
•  Clamping Voltage Vc Max:   146V 
•  Diode Case Style:   DO-214AB 
•  No. of Pins:   2 
•  Packaging:   Cut Tape 
•  Peak Pulse Current Ippm:   69A 
•  Power Dissipation Pd:   1.5kW 
•  Reverse Stand-Off Voltage Vrwm:   70V 
•  SVHC:   No SVHC (16-Jun-2014) 
•  TVS Polarity: unidirectional
