Ali ,the measurements in the spreadsheet were taken from Stans coils,not my own. Everyone who recieved the dvd's with the spreadsheet, I will tell you what the different readings in the tabs mean.
First tab "Loose coils" are the reading of each vic coil without the core installed.
Second tab "On Core Open" means the core was installed,and all of the coils were not wired to anything,all leads were open.
Third tab "On Core Closed" means the coils were on the core and all of the coils had their wires twisted together,except the one being tested.Each coil leads were twisted together seperate from the other.I mean when the primary coil was tested,the secondary coil leads were twisted together,and each choke coil was twisted together,all sperate from each other.
Then of course the last tab was the cell readings.
I hope you all understand this.If you recieved a dvd from me and you don't have the spreadsheet let me know and I will email it to you.I didn't get it on the dvd's,forgot.
K11 is G into figure 2 Digital Control Means K10 is Q into Water Injector Circuit,not shown in schematics K3 is B into figure 6 Gate Pulse Frequency Generator The second K3 is actually K21 which is C into figure 7 Phase Lock Loop
Pins 3 and 4 of the 4046 are not connected to each other.
Pin 3 goes through a 22k resistor then hooks to the negative side of the primary coil,and does not go to ground like your drawing shows.The 22k resistor and the cap are not connected to each other either.The 22k resistor is just added on the board in a spot close to where it was needed.
Pin 4 of the 4046 goes to the input (G) of the cell driver circuit.
hydrogenmask,pin 3 of the PLL 4046 is the comparator in pin.That signal comes right from the negative side of the primary coil through a 22k resistor.Thats the small blue jumper wire on the front of the VIC board.It also goes to the ANL/FREQ switch on the front panel,and then that signal goes to the BNC test connector for scope reading.
Pin 4 goes into G on the cell driver circuit,and pin 5 is the inhibit input from the 4001 from the Gate Pulse circuit A.
Pin 4 and 5 are not connected together anywhere.If someone shows it that way,their wrong. The 4017's are not used.
That first quote was when I thought the primary coil was the feedback coil.That statement was made early on before I had more time to check out the coil pack better.
The second quote was made before I found the diode on the vic card at a later time also.
Everything I write now is just as I have found it with Stans stuff.If I'm not sure of something,I will state that it's my opinion.But if I say it's how it was,you can be sure that's how it was.
These post do go back some time now,and so much has been learned since then. Don
Yes how many times do I need to repeat myself.Everything I tell people here is just how it was.Not every coil pack had three 220 ohm resisters on them,I don't know why,but most just had one 5 watt 220 ohm.The one I took the picture of had three.
I don't know why he had them different,I can just tell you how they were.Some of his things just don't add up at times.
Those two diodes were on the VIC circuit card and not in with the coil pack.
I only use the diode in between my mosfet and primary coil.If I add the diode across my primary,it makes the current jump by about 10 times.From 30 milliamps to 300 milliamps,so I don't use it.
Kali, In Stans circuit,there is a 5 amp 1000 volt diode between the TIP120 and the primary coil.The way you keep explaining your ideas,sounds like your putting the TIP120 after the primary coil.That diode protects the TIP120 from high voltage back emf as I see it.
Stan also put a diode across the inputs to the primary.From ground to positive.
As for testing my coils,if you don't find resonance,the voltages are all over the place at any gien frequency,and the scope traces look like junk.
Yes 57 khz is the primary resonance frequency with my coil.It is very easy to find,I'll take a picture and post here. Don
Update: Pics added
1st Picture primary resonance @54khz 2nd picture out of resonance @ 2.4khz
The primary coil was measured with the resistors removed.All coils were measured unconnected from the rest. All of my voltage measurements were taken at resonance.When pulsing the primary coil with square waves,you get sine waves as an output of the secondary.I would have to retest to see if the step up ratio shows up. Don
Update: I just tested my coil setup and this is what I came up with,
100 turns primary, 1000 turns secondary 12 volts dc applied to primary
Now I performed two test,one without bifiller choke coils on core (not connected to anything)and the other with chokes off core,then tuned to resonance with scope.
First test without chokes showed @ 120 volts out of secondary, just hooked to scope leads, and resonance was at 57 khz.This gives you a 10:1 stepup.
Second test with bifiller chokes on core and not connected to anything, gave @ 250 volts out of secondary,just hooked to scope leads, and the resonance was at 32.8 khz. This gave a stepup of 20:1.
So there is something happening with all coils on the core.It doubled the voltage out of the secondary.
The 220 ohm resistors were like I said wired across the primary coil(parallel).A friend had talked with a coil manufacture,and they told him that 10.5 ohms coil would get hot,then he asked them what would happen if you were to wire a 220 ohm resistor across it,and he stated that it would run cooler.Not my words.
As for the NVR1550 diode,there is actually a MUR1550 and a MUR1560.The first is a 500 volt,and the second was a 600 volt.
Kali,as for your explaination of the voltage step up up 1:5 with 12 volts in and 60 volts out was a little confusing.But I believe I understand what you were getting at.
You are stating that if you apply 12 volts to the primary coil,with a step up ratio of 1:5 you will then get 60 volts out to the blocking diode.Now in my testing of my coils,I have a step up ratio of 1:10 or as I would put it 10:1.So if I apply 12 volts to my primary I should get 120 volts out of the secondary.Right?
Well when I test the output of my secondary without any load on it,I get a much greater step up than 10:1.I've seen several hundred volts.No just maybe that is what Stan is hoping for with his set up.Maybe because we are restricting amps with the choke coils that this high voltage from our secondary is able to stay high,because of the very low load.
Under normal step up coils we are appling loads to the secondary output which pulls the voltage down to the actual ratio of the steup.So just maybe with the chokes restricting the amps,we are able to keep this higher voltage than the stepup ratio produces.Maybe it has something to do with the coils all being on the same core that allows this greater voltage to be produce.
Now again with my coil set up,of 100 turns primary,1000 turns secondary,and 2000 turns chokes,I have seen between 1kv-2kv at the cell.It it hasn't had any ill effect on the blocking diode.And my diode is the same rating as a MUR1560.
Thats some of my thoughts on this matter as I have seen it with my own testing. Don
Here's the resistance values that I took from the coils with a Fluke meter. Primary-10.5 ohms Secondary and chokes-70-75 ohms Feedback-11.5 ohms
Now 29 gauge wire measures 81.83 ohms per 1000 feet,so I come up with the following
Primary- 128 feet Secondary and chokes- 884 feet
As for number of turns I come up with Primary - 600-650 turns Secondary and chokes - 3000-3500 turns
Because they are hand wound and not precision,these should be very close.
As for the 220 ohm resister,they were wired across the primary to restrict the current feeding it.10.5 ohms will make the coil heat up with 12 volts feeding it.Some of the coil pacts had three resistors across the primary,all of them were 220 ohm.The largest one was a 5 watt. Don
