Step Charge Waveform (scope pictures)- am i on the right way?
« on: September 30, 2015, 21:46:43 pm »
Hello to everyone.

On my experiments with Stanley Meyer WFC, when i connect the scope probe over the cell i got this waveform:
(http://xblade85.no.sapo.pt/HHO/step001.jpg)
(http://xblade85.no.sapo.pt/HHO/step002.jpg)

My setup is;



Signal generator: Arduino nano v3 with square wave generator program based on tone.h library (timer2)
 
-Frequency 3 to 4 khz (dont remember exactly).
 - Gate on time 45 milliseconds
 - Gate off time 50 milliseconds


Transformer:

- Core: Flyback TV Transformer
- Primary: 160 Turns 0.5mm enamelled wire (0.0155in)
- Secondary: 320 Turns 0.5mm enamelled wire (0.0155in) (Just for test - 1:2)


Chokes:

1 Bifilar coil of 95 turns  0.85mm enamelled wire wound on ferrite rod with 9,5mm diameter


Power: 12v car Battery

Cell:

2 tubes with 80mm long
inner: 14mm x 0.7mm thickness
outer: 22mm x 0.7mm thickness

Both 304L Stainless Steel (used for water in houses)
The outside tube of the cell was isolated with ISLARC insulation Spray , ONLY THE OUTSIDE FACE OF THE OUTSIDE TUBE


Feel free to comment and to ask.

Hi
are you using an air gap in the core?   
in fly back mode it uses the air gap as energy storage but used as a ferrite core no air gap is used

might be able to run 2 tests , with and without

Hello.
Thank you for asking.

Im using it without airgap.

I believe that air gap is just to avoid core saturation and / or reduce the inductance

i tested the same setup with a toroidal ferrite core with outer diameter of 28mm from car audio amp, with the same windings as on the tv flyback core,
It worked better, but was a b*tch to wind!  :D

I dont believe at all that Stan's transformers was Flyback topology, but LLC transformer (resonant transformer, that ones that uses separated coil formers, instead of one over another).
See on google: LLC resonant transformer.

Thank you.
But what makes you think that this is the correct waveform?

I looked into Tony Woodside scope pictures and it is different from ours too.

Very confused.

Maybe the propretaries of the stan“s estate should test the VIC as they did publishing a lot of info like schematics and pictures of the original stuff.

Flyback transformers used reversed secondary orientation, and power is transferred on switch off.
If the draw of the wirings is correct, it cannot be Flyback topology, right?

This is what i thought, not as it must be, correct me if  i am wrong.

Me scope was on DC mode, sorry.

If i put into AC coupling mode, the 0 (zero)  point stays at middle of the waveform.

The scope probe is on X10 mode.

With this setup, the peak to peak voltage is about 50v.

With toroidal transformer, i used 30V input and output peak to peak reached the 300V with good bubbles.

I will replace the transformer with the toroidal one, maybe next weekend and take a video of the tube cell.

My current setup produces low with this transformer, but consumes only 150ma @ 12v.

My waveform "zoomed":

It seems to have some kind of "step charge", what do you think?
