Use for the Tesla Switch

[JANGYD]

Happy to be here again

I see spikes as high as 35V maybe higher at the switch points but only at certain frequencies. At others frequencies, no spikes. I think this is the critical point to get to. We all know (at least JBers) that the spikes are current or mostly so.

Leroy,
That is where the magic is, The spike is the key to the Dirac Sea that is where the negative energy pops out of, chase the spike.John B

Hi All, very happy to be here again and get to research.

Leroy,
How about your machine with 35V spike?
Can your battery charge itself with the Scalar Chager circuit?

I'm also seeing the spikes as high as 30~34V, but my battery can't charge itself yet.
I remember JB also mentioned the 35V spike on #850 post.
I am not sure about the spike I am seeing is the same spike as JB's mentioned.

Recently I got to big progress with the potential switch and I'm going to review all of the JB's Posts again.

I hope I have good result after some experiment.
Thanks

Oh cool, thanks for the link to the trafo. I have 3 x 1kva trafos at home, but it sounds like those would be to small. It sounds like the two 22ft strands would have been the two power pulsed strands and the 28ft strand would have been the one to go forward thru a FWBR into the large uF cap to power the load eh?

It sounds like I can get away with just 3 strands then. Is that right?

How were you firing the switching? Is it flipflop where you fire switch 1, and then fire switch 2 and then back to switch 1?

Or is it setup so that you fire switch 1, then off, then fire switch 2, then off, then fire switch 1, etc?

The difference being, The first method noted being back to back firing of the switches, and the second method interspersing off time in between each alternate switch firing.

It seems like the trafo core is only used then to Up the Inductance value of the 14awg strands which at 80ft air core is about 400-500uH of inductance. (at least on a pittsfield coil form). Adding r60 welding rod to the core brought it to 1mH-ish. It also brought the frequency way down. My trifilar 14awg coil runs right now at 30vdc and .8amps and at a frequency of about 12khz-ish. (just noted for reference or comparison)

How long do you hold each switch closed?

What is the frequency you have found to be the most functional?

I did draw out the setup over the weekend and went thru some mental acrobatics trying to understand the flows in the circuit and I think I do understand them now. I don't know that I need to start out that big, but perhaps I do.

Since you noted such big wire as #6 at such low turn counts you would probably have to be running the setup at a high frequency to still be able to dephase the current from the voltage on the inductances.

Good stuff. Thanks for sharing, look forward to further interaction in attempting to understand and then build this device. (add it to the other 30+ things I've built over the last 6-7 years now, hopefully tho this one is showing a cop > 1. )

Take care,

Its just rough drawing. I used a 3 kva transformer body as you noted. You can buy one here.
This transformer is easy to break down and reconfigure.

I bought a 10 lbs spool of 14 AWG and used about 5 lbs total. I put alot more on it than was required according to the math. It says to use 3 strands of #6 square wire. 2 strands at 22ft 1 strand at 28ft.
I used 14 because of cost. So I went with what you noted. BUT!!! your gonna have to pack the spool with wood on the interior and come up with some kinda way to compress the wire as you go along. If you don't pack that wire in your gonna get alot of heat and waste energy. Air gaps in the wire cause capacitance that also causes over saturation.
Just read up on transformer construction before you put it together.

You'll need switch's that can handle alot of amperage, so don't start out small or you'll just have alot of fires.

If you really going to build one and you need some help ASK!! I'll try to help.

I use 2 wires for each winding on the transformer. So 6 six pieces of wire total.

I don't have any off time between switching. I haven't found a difference between using and not using offtime.

I have varied the frequency alot during testing. Around 100 hz (both switch's fire 1 time per hertz) delivers the most amperage. Around 1 khz delivers a nice spiking effect. Just play around you'll see the difference.

You could probably use a smaller transformer if you have one. And wire for that matter. I want to be able to put all my batteries on mine eventually and see if I can pull a 2-3 kw load off it.
Just make sure your output wire is hair longer than your input so your voltage stays up after you rectify. You could even wind it for 120vac. Or use a 120vac to 12-14 vdc tranformer. That would be up to you.

It works good. I have steady running a charging setup (for other batteries) since Saturday. I charged 6, 2000 amp hour trojan 6v batteries from a golf cart. My voltages in the batteries that I am using in the switch have only gone down and average of about .10 per battery.
So....It works pretty good.

Cool Matt, Thanks for the additional info. What size did you note the batteries you are using at in terms of Ah? Are they also the 2000aH batteries?

I think there are maybe two things to consider, the large batteries will take a long time to run down but at the same time you need the large batteries to be able to deliver a large instantaneous current to the powered switch. I don't have any big Ah batteries like that. I have several old auto batteries and 6 or so of the 7Ah Gel Cells. I have two old 6V gold cart batteries but they are in bad shape and don't hold a charge. They were donated to me by a pal.

Are you able to measure the current pulse size during the 1hz on time versus the 1khz on time? I would expect the amount of instant current to decrease with the shorter On times...

I will probably use a trifilar 18awg stator as the "transformer" and I can add or remove R60 rod to increase/decrease the inductance of it. The resistance is about 2ohms per strand... higher than what you're looking at which is about .2ohms per 80ft strand of 14awg. I drew out the switching using the typical bedini mjl21194 and I think I have that slotted in properly.

Once I build it I'll let you know what I see. My results will be limited by what I have available... One other question...are you able to measure the inductance of the windings?

Thanks again Matt.

My batteries are 115 amp hour Marine deep cycles but they have a cold cranking amp rating on them. I am not sure if the 2000 amp hour batteries are full or not. They seem to not be in good shape but I am working on it.
I am kinda thinking about using some big caterpillar batteries (1500 cca) and seeing what they can do, but I gotta save some pennies up for them. I think an auto battery might work better.

I'll measure the inductance (If my meter is big enough) and add it to this thread.

Good News!

I just wanted to update on my schematic that I posted above.

I have been charging a separate bank batteries now for the last 5 days. I have been watching the voltages in my batteries. 3 times now I have charged the other bank of batteries as full as they'll get in there current rather poor state and all 3 times my batteries in the TS have growth in overall voltage.

Its not much. In fact usually after an 8 hour run at what ever frequency, the average growth is about .05 each time per battery, but its energy in the BLACK not the RED.

So I am pretty tickled right. If I didn't have to go to work this morning I would start opening the beers. but...

I have another computer (Parallax Propeller) that I am trying to learn the code for. It has alot of capability as far Data logging and the like. So I am trying to work out way to start collecting the overall performance of everything so that I can show the total gain in energy. Right now its kinda hard because I am pulsing the charge batteries some times and just regular charging at other times.
So I got to work all that out and I'll get back with ya guys.

Fwbr??

G'Day Gang,
I'm new around here and get a bit frustrated when I can't work out what the acronyms mean. Can someone please tell me what FWBR is?
Also is it possible to have a listing in FAQ's of acronyms used so silly questions like his can be avoided.

Cheers

Hi Dennis, That would be Full Wave Bridge Rectifier. Not sure if there is such a listing.

@Matt
Compliments for the progress that you have achieved.
I'd like to know if the tests are done under load.
Thanks for sharing.

A Google search for "electronic acronyms" returns almost 1900 results so I'm sure you can find some answers that way. Here is one list although it didn't have FWBR :Table of Acronyms
It's plain text format and does have quite a few so an easy save and search file for you.

Yes, thats kinda the point. LOL it has to have a load. In the above case it was batteries being charged.
