Welcome Dan


1. Different WFC systems use different cores and VIC designs, there are different ways to accomplish the effect, however elusive... The toroid was mentioned in one system, the bobbin type was the latest, most advanced VIC design, possibly worthy of superseding all previous VIC designs. Toroid VIC's are not economically simple (mass production), while bobbin VIC's are. The context of Stan's development spanned from 1975 to 1998, and over the years his systems advanced, so keep that in mind when trying to sort out what is what and what goes with what, some details are separated by years of advancement.


2. The taper resonant cavity is part of an advanced and complicated system, and there are not many people there yet, see Hardkrome's project section.

Yes the time span is a little difficult to overcome but its clear the most recent patents/notes are the more efficent design. The taper resonate cavity, I find very interesting. As soon as i am able im going to have one machined. I may not have the driving ciruit but i would like to see if voltage potential is higher at the ex. port using around 1Kv

To get the increased voltage effect from the taper cavity you have to use it as a wave guide, just applying a voltage to it and measuring the voltage at different places with probes is not going to show you the required effect, it's an electromagnetic wave traveling down the cavity. if you are not using it as a wave guide, then the properties of the wave guide will not exist.

well listen to stan words


transformer driven by unipolar square wave, with a switching diode and a common choke in series than into the resonant cavity and than the blocking diode and another variable choke... than water...


He states in the tech breath that the resonant charging chokes would provide undistorted signal, in this simulation it proves to work this way, without the chokes you are not able to sustain resonance on the tank without spending a lot of energy because the transformer become part of the resonant tank, this change the resonant frequency dramatically.... basically the choke will de couple the transformer and the resonant tank... the circuit shown have a 50:1 transformer that have 14 volts coming in and at 5khz consume 50W while having on the other side 9kv on the tank and ABOUT 700v going to the water... I assumed a 10kohm resistance across the water... if you raise the resistance you get far more voltage...


what do you think about??


inputing 150ma from the secondary and having 3 amps recirculating, seems to me like a 20Q factor... the resistance across the water is consuming about 45W so almost 90% efficiency.. of course in real like wont be this way however, is a good picture...


The secret in my opinion is to decouple

This would be closer to real life


considering a parallel resistance with the resonant capacitor 50Mohms


about 70mohm + 30mohm being mosfet and wire in the primary


about 100 ohm for the chokes and secondary


and 1 ohm for the resonant inductor..


of course could be a bit bigger but note how it don't change much the resonance, it reduces just a bit the power delivered

well this in my opinion would be an easier approach in that the input transformer is simplified, so it participates o the resonance inputing the energy in series so it don't need to be decoupled....


I've chosen to use 110v in order to have less losses on the mosfet in this simulation and in to be able to make the transformer step down witch lower the amps on the primary ...

I tried this last year and it work however i didn't had the choke to decouple the cell from the tank and nor distilled water...


think about if water start the resonance having about 10kohm and when full of bubbles become about 100kohm


try changing the values, you will see just what stan said


remember


changing water resistance change the frequency


changing the tuning choke change the frequency...
