Nick
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

Itsu I can't find that device easily.

Have a look at this list it's relatively easy getting most on this list at the moment but I dare say other people will find other devices in there country location ect

For Drain to Source protection, it seems the Littelfuse P6KE130CA will work.
It has a max clamping voltage of 179V, so should be ok for use with an IRFP260 MOSFET.
http://www.mouser.com/ProductDetail/Littelfuse/P6KE130CA/?qs=sGAEpiMZZMvxHShE6WhpuznpqHUCVB%2fRpZhPQm1SBiw%3d

P6KE130CA
Product Category:   ESD Suppressors / TVS Diodes   
Manufacturer:   Littelfuse   
Polarity:   Bidirectional   
Working Voltage:   111 V
Breakdown Voltage:   124 V   
Clamping Voltage:   179 V   
Pd - Power Dissipation: 600W <-- Mouser lists 6kW ???  The datasheet says 600W
Brand:   Littelfuse   
Termination Style:   Axial   
http://www.littelfuse.com/products/tvs-diodes/leaded/p6ke/p6ke130ca.aspx

The Littelfuse 1.5KE130CA also has a max clamping voltage of 179V, but can dissipate 1.5kW (1500W peak pulse capability).

Have a look at the IRFP150 transistor MOSFET enhancement  mode
only 100 v but 40 A and a conductive resistance of .055ohm less heat (more of a nail switch)
but if you use it use a P6KE56A protection TVS

We are only using 12 to 24 volts why not make use of it's power switching capabilities

IRFP240 200v 30a conductive resistance  .075 ohms

Also, some one else bounced this back, thanks (reducing to fit doesn't help)

I consider that 1.5KW (peak pulse)TVS a good choice. However, if Nick firmly establishes that the 'effect' depends on a very hot, over voltaged mosfet, then although a suitably rated TVS will protect the mosfet, the 'effect' may be lost.

Hi all :)

So summer holidays are already over... And I am katching up with the posts you guys made.

NickZ, Geo does not have self runner, yet. Like I mentioned before, we did about on 95% of replication with the main effect missing. Which is powering whole setup output from the ambient.
Also it is good to know you managed accidentally to get same effect as Geo had.

AG, the picture of grenade you posted have missing additional layer. And it is crucial to know, - the output of the grenade is the cold electricity HV which is charging HV caps superfast when the effect is in the place. Then Ruslan/Sergey and possible others used as attachment step-down inverter with async transformer for converting it into hot DC electricity..

In regards to wires. If you have impurity in grenade wiring it will cause heating, etc and catching the effect is next to impossible (that I was been told many times)...

Cheers!

Yes we did make a device (grenade using Aluminium foil) rather than a winding, this killed any effect at the time of testing, however it might be possible to wind a 1/2 wave experimental winding on a 45mm tube and place in the centre of the 50mm tube, with out knowing any details, however that didn't stop the effect on the original.

What we need to know is is it 1/2 or 1/4 wave of the 38meters or a wave concerning the Katcher assembly it's in tune with, I do so hate having to spend time and resources to reinvent the wheel when some one already has the details they might like to share ;)

Any one ?

   T-1000:
    Well, ok Geo doesn't have  a self runner. Sorry to hear about that. I was hoping that he'd hit on it by now.
So, no worries, I'm slow at this also.

    Guys,
    I made a couple of new videos late the other night and below are the two new links, to them.
   The first one is about showing possibly what might be some of the first signs of "effect generation:, without going into the caotic mode. With peaks maintained below 230v, or so

   The second video below is showing what may be the first part of the "effect" that is needed to get this thing off ground.

   https://www.youtube.com/watch?v=ofA-rtYe9hM
   https://www.youtube.com/watch?v=qO1wKH3CnIA

    The scope shot pictured below, is of the frequency of my drain signals at the time of running the "effect", 15KHz, and a few other important details in that digital scope shot. It shows when it rings into the caotic mode, but only with the induction circuit running, no Kacher on, on that shot. It's just a shot of my drains signals, on one of the sweet spots where it sounds like someone is trying to tune into Radio Moscow.
Or something like that.

    That scope shot below was taken tonight, on my new Siglent scope. Which is new, and it's great, and it's pretty.
And it's here, with me now. I took a screen shot picture of it, of my drain signals, from my cell phone for now.
And I'm sure glad it has the button called "AUTO", or I'd be lost in scope land without that button.

   I have to thank Dog-One, for his contribution of the Siglent scope. It is very much appreciated. And it got here to C.R. in like new condition, and it also came very well boxed. So much so, that I had to convince the customs duty guys here, that it wasn't a brand new scope, in its original box. When it was...
    An amazing gift...
   Thanks again Dog.
   No more blurry scope shots...
   Well, maybe just a few more blurry ones from my old Tectronix, at times, as it may still have something to show.

Nick,

Please show the mosfet gate waveforms in both normal and chaotic modes.

Nick,

the new scope looks awesome, take good care of it.
It shows nice signals with about 50V amplitude and a spike with a 333Khz (3us) ring on it.
Try to put the left markers (yellow 1 and blue 2) on the nearest horizontal line to better compare them.
Off course on the right side of the screen you can put up some measurements data like frequency, Vpp etc. but you will pick up on that soon.
 

The first video shows great operation, nice steady drain signals (despite the spike and ringing) and the additional brightness of the bulb
when the kacher kicks in.

The second video nicely shows the effect you get, but overall its not a that bad signal on the drains, i have seen far worse signals in chaotic mode.
The sound (about 2Khz??) tells that probably you have some oscillations going on back into the TL494.
Some decoupling caps 0.1nF (ceramic) across the plus / minus there could help.

Nick Z Nice scope display, nice scope, Is that the effect you're getting?
To me, it looks like you have found the resonant frequency of the yoke!
Try and see if you can improve on the effect that's happening between each off cycle (effect),
you can do this by changing the values of the 0.47 uf cap, try lowering it to get the 15 khz up a couple of cycles and see if it's amplitude increases, the fets should run cooler the. Try it and see how you get on.

PS don't bother with the Katcher yet.

Allen

PS some guys are experimenting with a winding under the grenade (equates to the grenades first layer in length).

Nick,

i was trying to focus on your Oleg snubber, but i have a hard time finding out how it is connected.
According to the below picture, is it right what i think i see, meaning the white wire is the 24V supply wire.
I cannot see where the other side of that resistor goes to, but it seems NOT to go the junction R, C and D's
Please double check the correct connections.

   Ok, well thanks a lot for the comments guys. And thanks to Dog-One for such a nice gift. It certainly will be put to good use.
 
   Itsu: The Oleg snubber is connected from the resistor to the one end of the black cap, (it's connected underneath the resistor), and the other end of the black cap is going to the two diodes. And from there each of the two diodes is going to the fet's drains. I'll show a close up in my next video. But, it doesn't really do much as it is right now.
  I should be getting the 47 ohm 2w Oleg snubber resistors, and the 1k ohm, 2 watt resistors for the fet snubbers on Friday.
   
   The frequency is reading 15KHz, on the new scope. However,  the 230 plus volts spikes and peaks are much lower than what my old scope was reading. As the digital Siglent scope does not really see nor read the faint higher peaks that my older CRT scope can read.

   I'll need some time to learn just how to use this new scope, as it has more tricks and whistles than I can shake a stick at.
The AUTO button is a great feature on it, as well as the big 18 div, 7 inch color screen.

   Hoppy:  I'm not establishing anything at this time. Nor am I saying the mosfets need to be going into any particular condition.
I'm simply stating what I see. But, it may be that while clamping the voltage peaks to run under the 200 volts of the mosfet limits,  that that may cause the "effect" to not be present, and not kick in.
   On the other hard, Ruslan and other guys start their device using only a 12v battery. So, even using that lower 12v input voltage can kick the device into that special resonant condition. 
   I'll show what my gate signals look like while the effect is happening, in one of my next videos. The gate, and drain signals do get affected by the HV pulses onto the induction circuits. Which also affects the way the fets work when in that special resonant sweet spot.
And so it looks like specially tuned snubbers are essential, to be able to obtain the effect, while yet not burn out the fets with  extreme BEMF peaks and spikes.
