Stan Resonance finally cracked! by Sebosfato

[Hidden]

Sebosfato, I'm waiting for core material to arrive.

Best thing to do is build it as Stan describes it in the patent.
You already know, it is difficult to understand how it works and how to build it.

I follow your 'theory' now it must be transformed into practice...

Nice hearing from you Webmug,


I'm now doing some calculations and trying to determine the parameters. http://ludens.cl/Electron/Magnet.html


In this patent Meyer clearly have TX5 resonating with the container therefore i'm going to use reverse engineering to calculate.


For example for calculating oriented grain core to work at 5khz having a cross section of 0,0006m2 and limiting the saturation to 1,5T you would need 0,1 turn per volt. So if you have 200 volts max in the primary 20 turns is pretty much what you need for the primary probably having a tap every 5 turns would be good. The secondary in the patent meyer says that should be designed to have 2000volts thus 200 turns is good for that.


From what i'm thinking the resonant charging chokes, at least tx5 must be made with thicker wire such as the primary 24awg cause it will resonate and therefore there will be a recirculating current in it. In other patent Stan says 100 turns for the chokes, and i think is ok cause when resonance happens its voltage can get over 10kv and thus restrict the amps even being of lower number of turns than the secondary. This could be right if we are not interest in keeping the 5hkz as working frequency. This could be wrong. I'm thinking that Tx5 should have the right inductance to resonate with the cell, here my cell (container) have 330pf thus for 5khz this give me 3H. If so calculation should be made backwards.


I'm going to make some coils here rapidly so i can do some preliminary tests. I will use the (I) side only of the (EI) core as the core, cause i think the all core is too much. I can't wait to see this working!


I'm thinking that when the TX5 positive (b-) voltage is greater than the B+ voltage the amps will be restricted cause the diode wont allow the current to flow in the opposite direction. Therefore restricting the current. Is like biasing.


And if you think well the bifilar would have no problem cause between the water plates theres not going to be too much voltage, only in reference to the outside. I think that a 3kv insulation between the bifilar wires is more than enough and i think the coating of the wire already is rated for this, not sure..


One thing still takes my attention, with 3H needed i think that i will need to make 1000 turns for achieving this, witch would become too high voltage if the transformer was to be designed from the primary to the secondary in conventional way.


Thus maybe the primary and secondary should be designed to not even reach half of the saturation cause during the resonance the core will saturate already in my imagination.


I thought of going in the reverse direction.


I have 100ohm 3H 200ma 20kv 5khz so the primary should be 2mh if i'm coming from 12v... 


Than the secondary i think that 450mh would be ok and also for the other choke.


Is what i'm going to do now.


Thanks for the reply webmug.

My testing coils are as follows:
Prim. 850uH 1ohm 200wnd AWG23 (100ohm series resistor)
Sec. 150mH 46ohm 2000wnd AWG30
Pickup center tapped 2x 15mH 2x11ohm  2x500wnd AWG30
Choke1 150mH 46ohm 2000wnd AWG30
Choke2 150mH 46ohm 2000wnd AWG30

Copper wire insulation should sustain 2k5Volt.
Inductance depends on core material used (measured values are without core)
Going to try ferrite core ( UU core )

My wfc cell is insulated in delrin. Wires are fully insulated.

Webmug what is your container capacitance? relative to the inner tube.
 
Wound a piece of aluminum foil on the outside of the container and measure the capacitance between the inside tube and outside of the container. Should be pretty much the same for the outer and the inner tube. but take the inner as the good one.


I think that having other tubes inside having way to switch would be good so we could change the capacitance i think, however i'm not very sure cause as water is also a conductor i'm not sure if the area of the capacitor in the inside is limited to the tube area..


This outside of the contained will be the ground you see in the VIC. Than you will have the resonant frequency from tx5 and the container.


I think that you should not use a 100 ohm resistor in series, if you work from 12v. This would be good if you work with 200v to limit the current and i think you should not get more than 30ohm... you must think about the voltage drop. if you have 100 ohms and you are using 100 volts and 1 amp flow you will have less than 1 volt going to the primary.   


I think that ferrite is ok, I will try also with that, as i have interchangeable coil formers.

Ps i'm now only winding the tx5 tx4 chokes to make some tests as i already had a coil former having 200turns with taps every 50 for the primary and another with 600 turns for the secondary...


And adjusting the core laminations number and or gap i think will be easy to find the right configuration to  achieve the resonance..

wfc capacitance is 1.8nF
I don't follow the 'ground aluminum foil' theory... (not tested) capacitance will be between the inner rod and the outer tube.
Dielectric between them is water.

The 100 ohm resistor is used to switch the MOSFET. When I lower the resistor value I don't have 50-50 PULSE square waves.
Lowering to 30 ohm could be possible, but it depends on the coils.
I know my current going into the primary is too low. I wanted to use a transistor as a switch for the primary but I can make it work. Maybe you know a good driver circuit. TIP120 doesn't work...or I'm doing something wrong.
