TPU related - I dunno???
« on: July 22, 2007, 02:09:53 PM »
So tonight I was doing some research in MultiSim 8 related to the Borderlands longitudinal wave videos on youtube. I threw this together in roughly 5 minutes with "sample" RF components. (going to redo it propper) I'm just hoping a familiar member with the software could help me more thouroughly understand whats going on here. Its quite similar to JDO's floating ground resonance coil, but if this is something unknown why can we simulate it?

Go figure, I found exactly what I was looking for and I'm more confused.

Thanks for looking,
~Dingus Mungus

P.S. I included the multisim document in the rar file.

Dingus,

I've been meaning to sim this up as well. CTGLabs (Dave) has done this test on the bench, and Naudin has done some work on it too, but his appears to be simulation only.

Naudin uses a specific resonant frequency for each case, and I am uncertain how he determined this yet. I still have to build it in PSpice and see if I can also obtain a resonant frequency for each.

How did you determine your frequency? It seems quite high?

Hmmmmm... I'm really curious if this is useful... I need to get all my stuff asap!

I give it some time to ramp up and level off at a low frequency, then I scan up till I start seeing the reflections. Its slow as hell, but luckly I have 4ghz and 4gig ram so it processes as fast as possible. The ultra high frequencies in example one were due to the odd RF components. I've also found that harmonics exist all over in this config, the lower the harmonic, the higher the voltage. Way cool... I just have no idea how to measure it more acurately or extract work from it without chnging the resonance.

Any suggestions???

P.S. Did you see? 420volts!!!

Hmmmm... Something is wrong here.
Could this just be acting like a step up transformer some how?
I'm getting it to ring to high voltages at all sorts of frequencies.
Definitely going to do a physical replication of the whole demo.

So no one else finds a single frequency creating its own harmonic counterparts as interesting then? Seriously I don't know enough about electronics to know where I should extract power from. Any suggestions guys?

Dc square wave using reflection and resonance to charge AC caps... It adjusts the frequency to a harmonic of the parallel circuit. I'm just listing my thoughts while I'm still working on getting my new equipment for physical replication. Anyone else playing with this circuit?

 Hi glad to see your playing around with this. I built one in coil fasion , JNL had the flat version and tested it , it's all on  his web site with all the  info you'll need, when tying it to get there in the ring fasion at high freq's it rams up extreamly fast and will wipe out your test equpiment and possably throught a few lighting bolts in the process. so be very careful.  I had other pressing things at work so I've put it on the back bench for a while.  when you see it hit over 800 volts it will go to over a 1000 very quick ! and things get real hairy fast. the feed back is instant and your valuable test equipement will get trashed in the process. keep it low and slow.

I'm trying to obtain a 60mhz scope and plan to use a protection circuit and isolated instrument grounding to prevent any smoke loss in my equipment. More questions remain though. Why can I see these effects in a simulation? How is dc square creating HV sine? If all the inductors are the same ammount of turns with low cap values where does this HV come from? I don't a whole lot about electronics, but this is all new to me.

Great to see someone working on this - longitudinal wave transmission lines. Well worth your time -- DO it in practice. On the simulation side you should read up on impedance matching networks for RF... thats probably all you will get from your simulations -- a realization that an impedance matching network is a great transformer. If you match a low impedance to a high impedance then you have a very efficent step up transformer.

I proposed a TPU configuration optimized for longitudinal waves in post #44 here http://www.overunity.com/index.php/topic,2764.44.html  It would be great to have some people working on longitudinal wave transmission lines.

cheers

Mark.
