Tests started and I'm very excited with the results


In my opinion you all should be trying too!

The frequency generator came very handy to work with it
Now it need to be updated with the code for phase lock with it..
Sweep works also nicely

Also I may add a gate based on pulse count...

The amplifier burned somehow so I could only test with dc pulsing ... no Sine waves

I added a diode in parallel with the coil and a irfp520 to just hit with

The cell created some kind of resonances

I believe what meyer talk about particle oscillation as energy generator... every flip you can add potential energy to the ions

I applies just few volts to see

I think the best way of doing it would be with the regenerative snubbed pulsing and having the coil tuned to this water resonance

That because it get a very high peak at start where current is min while it also allow the collapse at the point of highest current

Good of  Luck, Fabio!
I  pray that you dont burn too many components during the tests  :)

Cheers!

The electric field strength
« Reply #282 on: October 14, 2023, 09:18:52 am »
Thanks my friend! I'm being cautelous

Electric fields are the force im using on this prototype

This induces a movement of ions causing a resonance in all senses of the word

This resonance absorb energy but the energy get mostly contained in the movement of the ions and the dissipation related to it

The point is that combining the original fields with the ions resonating water step charge to the point it can discharge on the electrodes it's excess potential..

If we apply 1kv to a 10cm wire we get 10kv/m of field

Resonance can get wild specially using superconductors...

The bifilar coil
« Reply #283 on: October 14, 2023, 09:35:04 am »
Resonance mean that the voltages on the componsnnts cancel eCh other

The bifilar allow to take the voltage from one referential and conect to another

Check this article:

https://onlinelibrary.wiley.com/doi/10.1002/cta.2830

The main feature of a bifilar coil is it`s capacitance, that allows resonance without the use of an external capacitors.

A bifilar coil behave somewhat like a transmission line that mean that in the end of the like you can have high current or high voltage depending on the load

if you have a short ckt load you are going to have a high impedance input so you need to input high voltage for example….

im not sure yet what will come from this build but seems that im finally getting to understand something….

one thing more to consider yet is the ultrasonic resonance that can be paired

that because the resonating coil provides both fields and they kind of apply a force to water that is in the double frequency because of the interaction of the fields

nice article thanks for adding it to the topic!!

In fig 6.1 in tech brief meyer talk about bidirectional primary

This made me think that he actually have two segments of primary one in one direction and the other in oposite direction to minimize the capacitance between primary leads. While keeping tight coupling

This will be required to keep the switches safe

My idea I to have a capacitor in parallell with the diodes that goes to this two primary segments... of course also each segment is pulsed independently with alternate square wave...

What I found amazing is that coupling the primaries they will act to charge this capacitor when pulse is off protecting the switch while when pulse on it will use the capacitor energy to create a spike superimposed on the "square" or pulsed output

Why pulsed?

Well if you change the duty to 95% it will become a pulse with a core reset pulse and not a square

So it will become a kind of non dissipative snubber giving extremely high efficiency

With less parts than using the non dissipative I use to with a clamp coil because it needed still 2 diodes... (the result is not the same but is much more complicated so I'm giving a chance to Kiss method ... seems to me what stan would be doing..   

That gives huge huge huge enormously spikes on the output on both pulses on and off

Adjusting the space between the pulses is possible to manipulate how this spike will react...

The spike is caused because when the primary pulse is turned off the other coupled primary will first charge its respective capacitor to a high voltage! And this will be immediately discharged when it's switch now turn on...

Notice that all the voltage on the primary will be impressed on the other so If we keep the capacitor to charge to a maximum 1200v by adding tvs in parallel with the diode and capacitor and maintaining the input voltage up to 250v the igbt should never see more than 1450v

So what I'm saying is that is possible to create a very powerful output voltage

The secondary would be seeying 3 times that

I think this will help keep components little safer...

A snubber may still is desired just to keep dv dt under the specs but will be much smaller so lead to a much higher efficiency... actually I may use only tvs.. and varistors

And also I didn't mention reducing the capacitance between the primary leads will make it oscillate ate much higher frequency...

May seem stupid but this change in capacitance can change the game...

The reverse diodes on the igbt are of greatest importance for charging this capacitance...

The clamp coil may still be applied to reduce risks but still simpler I think in this way even If it will need two diodes and center tap now because it's bipolar protection now .

1/5 ratio of LClamp to L1 would limit to 1250v on the primary

This clamp coil allow the switch to be safer while throwing juice on the switching...

There's only two possible ways so I'm going to test both

One is two primaries wound over the other in same direction and the other with oposite direction... the goal is to get the comparison of having minimum or maximum capacitance between the primaries and how this translate to the output waveform... and overall efficiency in power output vs power dissipation of the switching and protection if any difference...

My prediction is that with minimal capacitance we get higher spikes since the charge will go to the capacitors while in the other case we get a lower spike and perhaps a resonant behavior at a lower frequency so it may filter the spikes few better but also cause higher interwinding voltage maybe too possible to arc in higher voltages..

They must be tightly wound with no defects and better be triple isolation coat

And dip into oil... the clamp coil must be right over it and perhaps  is better to keep within 1/4 of the primary... so it would need to be another half primary with a center tap


Wish I knew all this 10 years ago when I still had time to do all this alone.. I discovered that the only reason I don't get enough motivation is that I fell bad if I'm not working on my company because is being hard paying the bills ..

I guess as soon as the company grow I may have less time but higher motivation...
