Posted: Tue Sep 25, 2007 5:11 pm Post subject: Bifilar Chokes |
|

Ok, first I am going to start off saying that Meyer's used some energy. Meyer's states in the tech brief that he uses 12v@3.3a=40w on the primary side of the step up transformer, and at the wfc he is using 40kv@1ma=40w, so TOTAL POWER USED IS 40 WATTS. You can also watch Meyer's New Zealand lecture to verify this, which Site Admin has so kindly embedded in the top right of his web site , because it is Meyer's most informative lecture and gives the most clues on the VIC construction.
Now back to the original topic of my post:
The positive choke(L1) will be at resonance with the wfc(ER) and is expressed by F=1/(2*pi*sqrt(L*C), L being the inductance of the positive choke(L1) and C being the capacitance of the wfc(ER). The impedance of the positive choke(L1) and wfc(ER) is given by Z=sqrt(R^2+(Xl-Xc)^2), R being the resistance of the positive choke(L1), Xl being the inductive reactance of the positive choke(L1) and Xc being the capacitive reactance of the wfc(ER).
The total impedance of both of the chokes(L1/L2), wfc(ER) and the secondary of the step up transformer will determine how much amp leakage will occur, and is given by Z=sqrt((Rs+R1+R2+Re)^2+(Xl1+Xl2-Xc)^2), Rs being the resistance of the secondary of the step-up transformer, R1 being the resistance of the positive choke(L1), R2 being the resistance of the negative choke(L2), Re being the resistance of the wfc(ER), Xl1 being the inductive reactance of the positive choke(L1), Xl2 being the inductive reactance of the negative choke (L2), and Xc being the capacitive reactance of the wfc(ER).
When you get the VIC in to resonance by adjusting the frequency to match the inductive reactance of the positive choke(L1) with the capacitive reactance of the wfc(ER) and adjust the variable negative choke(L2) to balance the impedance of the circuit to keep a "Uni-polar pulse train" going to the wfc(ER) the current will be at a minimum do to the combined inductive reactance of the chokes and voltage will go towards infinity if the components would allow it to occur.
I believe this is the most important thing to understand and remember about the chokes; Meyer's states in the New Zealand Lecture and the tech brief that the chokes are restricting the amperage using MAGNETIC FIELD(inductive reactance) and not a RESISTIVE element! Meyer's states that he covered resistance to stop people from being able to get around his patents, because you can use resistive wire.
In Meyer's Tech Brief he states that resistance will reduce DC current and the transformers ringing effect. This just gives you a more clean waveform, but also decreases current and voltage. LCR circuits are well known.
Now we know that magnetic field(inductive reactance) is the big player in restricting the amps. "Now you have to learn to ask the right questions"(one of my favorite quotes from Stan) So, how do we create the strongest magnetic field? This is were the bifilar coil comes in and your knowledge of inductors. The bifilar coil is wired to use the wfc(ER) as resistance between the coils that will be electronically and magnetically oriented in the same direction(Meyer's states this all over the tech brief). Meyer's has a diagram with the chokes orientation(the dots at the end of the cokes north pole) on figure 7-1 on page 155 of the tech brief. I also included a diagram of how to connect the wfc(ER) to the chokes called "NEOGEN BIFILAR with wfc"(this does not show the right physical construction of the chokes just how to connect it). Because the chokes are electronically and magnetically oriented in the same direction this means that the positive choke(L1) and negative choke(L2) will be aiding each other by way of mutual inductance and causing more balanced opposite voltages at the wfc(ER). Meyer's has a good diagram figure 10-5 on page 200 of what the voltage is doing at the end of the chokes.
I'm going to reference a couple of figures in the tech brief and give a little explanation on them.
Figure 10-4 on page 200 it is actually two pictures in one. The skinny black wires are the schematic for the chokes(ignore all label on this schematic for how to connect the choke because it is very unclear and almost misleading). The Picture behind the schematic where the coils are cut in half so you can see the cross section of each section is how the chokes would be physically wound. Keep in mind it is still just a diagram so it is not the actual size of the wire nor the only amount of wraps you can put on each section.
Figure 6-1 on page 135 can be really confusing, because you have to look through all of the magnetic field lines that Meyer's drew. This diagram is also when Meyer's was starting to refine his VIC to be compact and to cause instant explosive energy from the water(his spark plug injector), but it is not necessary to include the step up transformer for just making enormous amounts of gas, and still possibly causing instant explosion of water. This will give you a good idea about how to construct bobbin for the chokes. Notice how close the section are to each other.
For the adjustable negative choke(L2) you can leave tap points out as you wind the coils.
IF THE CHOKES ARE NOT MATCHED TO THE THE WFC AND THE STEP UP TRANSFORMER MATCHED TO THE CHOKES AND WFC, THE WFC WILL NOT WORK RIGHT AT ALL. AMPS HAVE TO BE INHIBITED AND HAVE A UNI-POLAR PULSE TO GET THE VOLTAGE TO GO TO MAXIMUM, BECAUSE THE WFC ACTS LIKE A SMALL RESISTOR MORE THAN A CAPACITOR!
The VIC allows the water to become a component part of the circuit as resistance and capacitance.
Hope this helps you guys understand what I have learned.

Thank you so much for that Aaron!
I have made some chokes but I think they are to bulky and the wire is too thick so I am going to get the thin wire today and it should arrive soon. I guess I have to wind it by hand, dang! Oh well, I will post a picture of it when it is done.
Unfortunately I have broken my frequency generator, so I need to have that looked at, but after that I can start testing.
Thanks for showing the “correct way to connect the chokes”, I was connecting them all wrong.
So you just need to tune the frequency to find resonance? Ok, how are your experiments coming along?
Thanks for that help, and nice to see you back!

Very well, crux.
I am impressed and thanks for your insites. Its good to hear more of you.
I think that Farnell.com will be sold out on copperwire soon....
The dots were overlooked by me, to be honest.....

Crux,
And try to keep it all on one core, as Stanley sayd. He speaks about a UNIPOLAR MAGNETIC FIELD and magnetic field coupling.
Translated from the Stanley language dictionairy it means:
One core with all coils pointing with their + poles to the same direction, isn't it?
I also made a choke of around 1 Kohm yesterday. Its a nerve wrecking job. Yep, no amps. But also not so much bubbles.
If Stan the man speaks about a coil of around 11kohm, then the size would be impressive.
I used 0.1mm wire and got a coil of 3 cm long. 1 cm diam. and coil thickness of almost 1 cm.
I think we have to order for coils by a manufacturer. The 11kohm are almost impossible to make by hand. This thin wire doesnt give you the possiblility to wind in spirals. You have to go from left to right. Back in a straitline and again from left to right etc.

UNIPOLAR MAGNETIC FIELD does mean that the coils will have their North poles in the same orientation witch will give you UNIPOLAR/UNIDIRECTIONAL PULSES(Pulsed DC), and does not mean that the step up transformer needs to be on the same core. They can be separate. The chokes have to be on the same core as bifilar, because this gives you a stronger magnetic field to inhibit amp flow, and causes mutual inductance between the chokes witch aids them in producing higher voltage. The bifilar coil also has 250,000 times greater capacitance than a single wound coil(see Nikola Tesla's patent #512,340 www.pat2pdf.org), the bifilar coil also has resistance, so the bifilar coil is an RLC circuit. The wfc just adds resistance and capacitance to the bifilar coil witch completes an RLC circuit.
The size of the chokes will definitely be impressive if you are using 0.1mm(38awg) copper wire to get 11.6kohms, and I do not recommend you do the winding only by hand. You should use a lathe to assist you in winding it by hand, so you don't have to spin the bobbin yourself, but just guide the wire on by hand. Again, If you want the best possible chokes then you have to construct a bobbin with a lathe that will keep your bifilar coil in the right shape that you want. Look at Figure 10-4 pg. 200 and look at Figure 6-1 pg. 135 to give you an idea for the construction of the bobbin, also look at what Meyer is using for the core on his VIC(a bundle of steel welding rods cut to size works great).
Once the chokes are built right they will keep amps to a minimum even when out of resonance. When in resonance the water will just "fall apart" and amps will remain to a minimum and voltage goes to maximum.

Crux,
1. My thoughts whent to the following theory. What would really happen when you have the stepup
transformer and chokes on one coil? All pulses together would make a bigger magnetic field? So
better reduction of amps?
2. Today a made a second coil of 0.1mm wire, just to have 2 of them. No results there.
3. I just hooked my bifilair coil to my DL circuit and must say that it gives me with a pulstrain the
best results sofar. I started to make a bigger bifilair coil, for compare reasons. I let you know the
results.
4. Just a question that keeps me occupite. I have a toroid 230V - 24V. When I turn it around and
connect it to the DL circuit, I get around 40V. BUT, it depends on the frequency of the DL circuit.
When I have ok voltage, my resonance in the coils are gone. Its a choice. Or nice voltage or
resonance. Perhaps I have to forget the step-up trafo and redesign my DL circuit with a higher
voltage on the Mosfet.
PS.
I dont know the word lethe. You mean some kind of structure for helping wiring?
Sorry for my bad english. Its not my native language.

Question to you all.
Tesla uses a spiral as coilshape. Can anybody explain the difference between a spiral shape and a "normal"coil like a transformer?

I believe Meyer's talks about the reasons for incorporating the step up transformer on the same core as the bifilar chokes in his Colarado Lecture.
Remember the chokes are typically 11.6kohms. I am trying wire sizes 38awg to 44awg. You can do a google to see what that is in mm.
The best way to get higher voltage to the chokes is use a step up transformer. I am still trying to find a good step up transformer for the wfc. I am aiming for 12v to 600v and above.

The advantage to using multi spiral coil sections is that the voltage between the wire will be very little in comparison to a standard longitudinal(normal) coil with layers, and also provide a stronger magnetic field.

Take a good look at the changes below and tell me what you think. |
Aw it's fun to look back at my old diagrams.... As you can see I have learned a lot since that was drawn. Yes, you made a great correction to that diagram.
By the way I also know now that none of Meyer's coils are trifilar.

|

crux,
It's great to hear from you again.
Your insight into the VIC is great.
I've been experimenting with the VIC design, transformers and chokes using some U-Cores that I've been able to acquire. Actually creating the Transformer and chokes has helped me to understand the various relationships of current, amps and windings to a greater degree. I've been cycling between measurements reading Stan's notes and reviewing transformer and the RLC formulas. And I have finally come to the conclusion that we should be able to reach OU without conditioned pipes once we understand and build the VIC circuit. The key being that getting the VIC to resonate will send voltage well beyond the minimum required to break waters covalent bond. I have read somewhere that Stan said it to be 1500Volts with no amps, but I don't have an actual reference for the 1500Volts.
On WO Patent # 92/07861 he indicates the following:
"In a typical operation of the cell with a representative water capacitor described below, at a frequency of about 5 KHz at unipolar pulses from 0 to 650 volts at a sensed resonant condition into the resonant cavity, conversion of about 5 gallons of water per hour into a fuel gas will occur on average."
I'm curious if anyone has experimented with a Neon Power Supply.
Here's one that converts up from 12VDC to 4000V with a max input amperage of 1400mA.
Would it work to set the PWM signal through such a device?

I was thinking about using neon xfrmrs as well. From what I can see there are several for cheap available that have a 50:1 step up. It seems to me that two could be used together (secondary of the first feeding the primary of the second) to gain a ratio of 250:1. The WFC chokes would have to limit the total current to below 1mA (or else the secondary of the first xfrmr would burn out).
Another possibility could be to hook them up with the primaries and secondaries in series and use the primaries with V-common on the center tap and +V on the ends. This would, in effect, double the voltage out (i.e. combined 24V in, 1200V out).
Just throwing some thoughts out there...
