nano pulse power supply
« on: November 29, 2016, 07:21:58 AM »
Hi. Guys. Sorry my noob question. Power supply modified by les banki using 12 v battery or 220 vac from house? :)

12v DC , circuit Les designed based on japanese research papers , with primary circuit protection for spikes from fast switching .
like most circuits around ,if not ALL , 50% square wave is used , which no matter the freq is just on and off for equal length of time .  if used with flyback it is in continuous mode

.A fast MOSFET driver chip  can do a faster job down into the 10ns range if required. RF transistors such as the 2n3866 and its complimentary PNP can boost the avg current if required. The special thrysistor SCR is a gimmick.
Use small electrodes for experimenting and scale up the electrodes and electronics once you find the sweet spot.
Note that for electrolysis type work the discharge phase of the driver is not used as you normally want the charge on the double layer to discharge into the water not back into the driver.
As a side note, these pulse techniques are used for electroplating not for electrolysis as diffusion to the electrode is normally not much of an issue except for dilute electrolytes which are not used when producing HHO. (Expect for fringe science experiments  :o   8)  )

that " gimmick" has a part number just like every other component . manufactured by NGK by the research team in the japanese paper .
no one has access to the component part nor can anyone or has anyone given an explanation on how they think it works .
Les Banki designed what he saw as an equivalent circuit .  Stephen , the owner of this forum wrote the first post that out put was "31 times more than faraday" , Les did calcs on those figures presented and said "8 times" . 
from that point on everyone piled onto Les ,which went to show they didnt even BOTHER to read the japanese or Indian papers .
even when he asked them to read the papers!   

the researches in the japanese paper are also employees of NGK and also the patent holders of the thyristor .
their names are right there in the paper.
anyone can search for static induction thyristor or static induction transistor , theres research papers going back decade/decades or more .  they are not available to public .

theres heaps of info , patents and papers on the net , the static induction transistor was invented in japan in the 1970s !!!

http://www.sciencedirect.com/science/article/pii/B9780123820365000094

theres probably half dozen people who actually read the papers Les refered to other wise the threads on over unity and over unity research would not have gone the direction they went

and it wasnt because of Les Banki

Yes, just saying that you can do same research yoursefl without the special SCR.
Edit, the 555 needs a few more parts,I managed to use it with 74121 with a 7667 driver for down to about 30ns from memory. I did not try high voltages, since I used strong electrolytes.

So its means that les banki circuit not for electrolysis but
electroploting

No, he designed it for water splitting, but in general anything that can supply huge currents for, usually , milliseconds can be used for pulse electroplating.

Can I use this kind of power supply to generate hho from my 100 plates ss 316l series wet cell?

Yes but with 100 plates the voltage across each cell is 100th of volts at the coil. So you don't get the high voltage which is supposed to be vital. There is a minimum voltage for each cell required before electrolysis can begin it could be 3-4 V for stainless , i don't remember so 400 to 500v might be needed.

Ok thanks for the information. I read the book of george wiseman that if we use 3/8 inch between plate the voltage across each place 2v. That means the minimum of electrolysis occurs 200v. Correct me if I mistake.

What les meant by using this :

i. "... I choose the ETD49, N87, 0.5mm gap (Epcos) ferrite core transformer for several reasons.
The main one is power handling.  (200 – 500W, depending on operating mode, etc.)
Operating frequency range is another.
Availability is also important..."

ii. "...A single, HV, high current MOSFET, (Q1, 1500V – 20A) will serve as inductive current level/limit control and pulse generator..."

iii. "...D1 & D2 are also placed on heath sinks with 1200V/30A.
The power ON-OFF control circuit has also been modified to accommodate both positive and negative signal polarity ON control..."

Thanks...

I have not built the Banski circuit so can't help with specifics. Test one cell by itself first to get the total V required.
