Kapanadze Cousin - DALLY FREE ENERGY

  Itsu:
  I've got my grenade/yoke coils working, although with just the smaller fets for now. And I have the Kacher working, also. The problem is that when I try to connect the Kacher's secondary to the ferrite rod, and to the antenna, the output from the Kacher is killed by doing this, and no output is noticed on the antenna coil.
  I also removed the 4 turns of wire (opposite wound) on the end of the Kacher secondary, and now I do get a small spark that does cause RF burns, but minor, compared to the Joule Ringer's output.  But, still no output at the antenna coil.
  Is there something that needs to be done so that this does not happen?

You have 2 issues about kacher fails:

1. Your kacher antenna is to close to grenade. That stop kacher working. Make the antenna larger around grenade and you'll be surprise. Make sure antenna don't touch grenade or anything else.

2. Your kacher primary is tight wound over secondary. Make it larger too, and in no touch with secondary.

This things maters a lot for a good working kacher. For details about that take a good look at ruslans setup in the picture attached, how larger is his antenna and primary. 
Good luck !

hi itsu,

May i ask is your circuit able to maintain this high peak at around 1500kv at repetition or firing rate of around 25khz...34khz.

I am curious what ferrite material are you using for your toroid which is coded blue or cyan in colour.

May i ask which circuit are you using.There are many to choose.My requirement is simple to get to 1.5kv at least at around 100ns...300ns which is half time period of
kacher 1.66Mhz ~602ns

The latest one i have seen today is attached for reference.

Magpwr,

"repetition or firing rate of around 25khz...34khz" will be at the threshold, you need good cooling (heatsink with fan) for both
the MOSFET and the D1 diode, see circuit drawn up by verpies on the same page 58 as mentioned above:

The blue toroid is just a choke, i have no specs on it

DSRD used (not visible in the above diagram) is Russian Diode KD226D (Si-D 800V 1.7A)

@ NickZ

You also have too much turns on your kacher's secondary. I estimated based on Ruslan's latest videos kacher secondary have around half length of grenade length, and a thickness about 0.8mm diameter. He have in no case a kacher with hundreds turns. Observe for a clue Akula's kacer secondary from photo attached, it have few tens turns only.
But for first you can leave as it is for now, and deal with antenna and primary arrangement.

Skywalker, I think, it is very individual how many turns is on the primary. Most important I see to have this primary in resonance with the secondary. This is what I am still fighting with too. I change my primary to copper tube which allows me to test tap in different places. Unfortunately it seems that my copper tube is still short(I have around 3 turns) but not too far where it should be.  Check on internet how to properly tune Tesla primary coil.

hi itsu,

Thanks for pointing me to the circuit.I will assemble one now for testing.By the way are you able to point me where to buy KD22D diode online.There is none in ebay.
I got few of the Silicon Carbide Schottky Diode 600volts rated with "zero" recovery got it for $2 ea in ebay.But no news detected in using as DSRD in nanopulser.

There is a interesting discovery i made and solved while i had 74HC132 nanosecond generator on the breadboard with my DIY 74HC132 PWM generator (Fastest dual output channel PWM generator tested to 3Mhz.Circuit was uploaded weeks back no changes since and already implemented into PCB design).

If for example TC4421/TC4451 or TC4420/TC4452 is connected to nanosecond generator even though there was no output connected to anything.I noticed there was small glitch appearing at the channel A and channel B of my PWM generator.Initially i used 6 ferrite beads on straight wire at the positive supply of the TCxxxx driver which solved this problem for good.

Subsequently i found that by placing FERRITE beads on straight connector wire there is 1.4uH created.Later on i just replaced with a <10uH inductor to nanosecond driver positive pins.

I'm aware the mosfet driver need very good coupling since it's required to produce burst which needs high Amps during the switching period.
