Kapanadze Cousin - DALLY FREE ENERGY

[lacphong]

magpwr,

If you have "photographic memory" why are you keep saying "you don't want to teach people this and that..." no one is asking you to teach anything.  I don't recall asking you for any schematics, I only ask you for advice on which diagram I should pursue, because I'm lost in term of how to get all the parameters right for the coils to work together...

I'm thankful for all your help so far, but please; a real "walking library" should be wise enough to not say such thing about themselves, and calling people fools and idiots... only a 10 years old would do such silly things... lol

Anyway, hopefully someone someday will be able to make a break through and put it all out there, to solve the world problem with energy once and for all.  So sicking tired of politicians and big company gaming with oil.

hi lacphong,

Well well if you  got patience of a watchmaker why not  just take your time in reading all the pages of this forum and provided if you got a photographic memory like i do with excellent analytical reverse engineering skill.

I consider myself like a walking library.

-----------------------------------
I seriously hope that you don't end up being similar to some of the so called active idiots in this forum whom keeps asking for circuits after circuit.

Like a fool i did all that like creating PWM and few types nanosecond circuit video with proper schematics and upload into my youtube after doing intensive testing.In the end i am still treated like a fool.

Do you think i really care now.

It's killing my research time by the minute.Bye

Hi AlienGrey,
I tried to wound the grenade coil with a couple different kinds of wire in the length of 38.5m, first with a solid copper wire, but it was very difficult to work with so I switch to stranded speaker wire.

But I realized that, instead of just blindly winding the coil, it would be helpful to know which frequency the coils need to resonate at, and how they're related to each other...so I thought I should ask the more experiences users on this forum for some advice, to point me to the right direction.

I was going to go with 28khz for the push-pull, then 14khz for the 4 layers coil and the grenade coil, but magpwr said it's a waste of time... LOL

Lacphong I can see magpwr's point 1/ what's the resonant pass frq of grenade ? No, did you wind it right ? yes  tune your device to that frequency ! still nothing then RTFN i suppose you need to start learning by reading 5 or 600 pages. Also if Tesla coil is going (do you think the Wave your sending it would make a difference) at 1.8 mhz and pass freq of grenade is pass frq of 1.8 mz but yours could be some other frequency.

Thanks for the advice Verpies. The attached image uses an isolated 12V for gate driving. Is that what you mean?

Yes, but these are not the most optimal configurations.  Also optoisolators are not the best choice for high performance designs nowadays (they have limited working hours, too).  Modern isolated gate drives make them obsolete in high-speed applications.

P-channel driver looks like a simpler solution.

That's only an illusion because P-ch MOSFETs have roughly 3x higher R_DS-ON and are more expensive and less available.  Also the resistors in the gate voltage divider will need to be high power ones for a 300V secondary supply.  These resistors have to be special non-inductive power resistors and they will heat up strongly, too.
Last but not least, the gate voltage divider will not be able to charge and discharge the gate very quickly so the switching speed will be limited. 

I might give it a try as i won't mess with all those separate grounds and isolated supplies.

It is worth to mess with all those separate grounds and isolated supplies because that leads to a high-performance universal MOSFET driver that comes handy in many projects (not just this one). 
IMO it is a solution to 90% of problems appearing in FE power switching circuits tried here.

Such driver is very robust (it protects the MOSFETs and doesn't break easily itself). It is immune to HV interference, easy to drive from 5V logic chips and extremely flexible.  It's not that complicated either. 
Its major disadvantage is cost, ...but it is money well spent.

The major cost contributors are the isolated DC-DC power supplies ( see here and here ). 
If your time is cheap, you can save money by building your own instead of buying ready ones, but that requires winding your own ferrite pulse transformer and some skills.  I could help you with the latter if you'd like me to.

Below are three schematics that incorporate two N-ch MOSFETs to make a universal high-speed bidirectional switch.
Note, that the most expensive one (depicted in Diag.3), nullifies the evil Miller effect, that is the major cause of MOSFET's slow downs and spurious turn-on_s due to high dv/dt pulses appearing on the drain.  Gate charge energy recovery is possible, too!

  Ok, well you can start by watching this video (below).
  Wind your grenade output coil first, 37.5 meters long, onto sink drain pipe. There is no further tuning on it needed.
   Don't use speaker wire of something other than the recommended wire type and gauges.
  Follow the directions on making the grenade's bifilar induction coil 1/2 the size of the output coil, or 18.75 meter.
Be as exact on making these coils, their wire turns and direction of those turns, as you can be. 
   Make a Kacher circuit, start with a simple one. Make your Tesla coils, primary and secondary,  Connect the secondary to the "antenna coil" through a ferrite choke.
  See if you can light a small 10w bulb, at the grenade's output coil. 
  There are lots of videos to watch, also, as well as lots of discussions here. So, get up to speed, so that you are well informed.
and don't have to do anything "blindly".  As that won't work.
  Ruslan's older videos can be some of the better videos to watch, and study. As they are simpler to try to replicate.
  Example: TopRuslan 13.

   Lacphong:  You can use the Ruslan diagram that was modified by Geofusion, on the next post, below this one.

   Guys: 
   Ok, I did find the previously unseen "interuptor transistor".  Which is NOT being used when making the Adrian self running video.
   So, it's not absolutely needed for a device to self run. 
   We'll see if the addition and connection of that transistor (of unknown type), will be effective for improving his performance in the future.  But, for now Adrian is using a SIMPLE Kacher circuit, and is still showing his device self running. IF True.

    If someone could draw up a diagram of just how that interuptor transistor is connected up to the Kacher circuit, it would be much appreciated.
    I'll asked T for his ideas on it. But, I'm not too clear about it. Maybe someone can add that transistor, (and it's values) to this diagram, below.
                        Thanks.
