Use for the Tesla Switch

[Kepszlok]

Its not the 2n3055 its the resistors. The turn off time is too slow.

Personally I use fets and IGBT's now with drivers.

The pulse width is also important, as some of what you are seeing is the impedance in the batteries kicking in. A decline in current and in a OPEN situation also a decline in current flow. Batteries can usually handle up 30 MS pulse then the impedance kicks in so the potential drops at that point.

The batteries will actually tell you when you have hit that point but it is algorithmic in nature and depends on the situation you are using to charge it.

The current Tesla switch (Benitez Switch) I run is heavily dependent on filters to decipher the signals coming back from the battery to determine the pulse width and shape. All that can make a difference.

This makes things a bit more clear. If i do an upgrade on the driveing part of the schematic, i will get more speed and less voltage loss on transistors. I will rebuild my circuit in that way.
Even tina simulation shows great decrease in voltage loss.


Also i had little time to read your whole pdf (hard to do anything if you got a job and a family ), but your desing are very simple and asome. Sooner or later i will also build that circuit too.

Tell ya the truth I don't know how his worked out, not sure if anybody had luck with it.

I put this paper out some time ago for beginners:

You might get something out of it. Most of the projects are affordable and you use what you need to use or buy whats suggested.

To date 14 people have had success with them, but I couldn't tell ya where they are now.

Thank you, will read it today!

Along time I have been at this, that why your refusal to listen to good advice has left you a past interest. My friend

Hey Matt I found your replication of the Tesla Switch, didn't know you were there.

Great Job.

Sorry Mikey you have one tech confused with another. I know...your easily confused being a beginner and all. Maybe you should read the document I posted. Lots to learn from people who know what they are talking about.

Matt

I thought I did read it but maybe I need to listen more and did not understand what the ICEHOUSE website had posted for the last 20 years.

It is my understanding that the Tesla switch uses a surge or spark going round and round to multiple batteries. Some used coils with the switching.

I am a beginner but that much should be true.

Some go on about splitting the positive. The way I have tried to get a grasp on this idea is in simple terms the mosfet switch causes a spark or arc on each times it connects and disconnects.

The function of a switch is to connect and disconnect.

This circuit like the cap dump has been around over 30 years with no large replications with any substantial amount recovered to run anything that I have ever seen on youtube or anywhere else.

people just won't post their stuff because of the misunderstanding of terminology.

It is a shame there are no decent working examples for practical use with so many of these age old technologies, isn't it?

The way I first got the principle (Correct me Matt if I am wrong) was a guy on youtube years ago had some relays he used to do the switching instead of transistors. The batteries went up slowly and in a few days he could burn some power off of it using a flashlight bulb.

Then after draining down the power he charged them up again over a period of days. I was sort of hoping that by 30-40years later someone could show a working unit atleast as good as that one.

It's kind of confusing to me when you go on youtube (The only Place to go) you find that the Tesla Switch is often used with Bedini SG wheels and cap dump type multipliers and on we go.

I wonder if anyone has a pure Tesla Switch. Thanks Matt for setting me straight. You are still my pal.

Thanks for mentioning it. I'm still not get the bottom of that, but i now i got this driveing method.

From page 20 #619:
"so I use this method to force the transistor to discharge the most voltage between collector and emitter, a quick discharge without base to emitter resistor."
And i founded this method on schematics here: http://www.energeticforum.com/attach...switch-scr.jpg


Does Jetijs or somebody actualy built that circuit what i attached? So far i had no luck with it. I tryed out couple of settings and loads, but in every way the batterys are started to depleat.
My first attached picture shows the driveing signal of one of the transistors (B-E voltage), the second one shows the output in the Graetz's AC inputs and the third one shows what's in a battery's poles (ac coupling).


Based on Bedini's driveing technik, i think it's needed to redesign this circuit. My opinion are the 2 resistor driveing methode causes that so low output voltages. And it's also needed to use other transistors like mje13009 or mjl21194 instead of my cheap 2n3055's.

Tesla Switch

Years ago i built Jetjis's tesla switch what i found in Panace university's pdf in the 28. page. (see attachment)

For lack of proper tools it was laying in my desk for years, but now i started to finish it. There are a little difference between the original and the current version of the ciruits because the CD4001 lonely was not able to drive 2 * 3 otpocouplers, so i added 2 small signal npn transistor for boosting the output.


In the original circuit, the decoupling capacitors was withouth a value but in other designs on the pdf i found 0.5 - 1F capacitors for the same job. I'm currently lacking of these big capacitors (will try to get some), so i put 10.000uF capacitors instead.
I think the decouple capacitors are wery important, because the output voltage gets 0.5V higher when i switched from 1000uF decouplers to 10.000uF decouplers.
Currently i was able to get about 6V DC and 240mA flowing trough 24 ohm power resistor.

For the initial test, it was running it for 45 minutes with small, 1.4Ah 12V batterys, but i noticed only a 0.01 - 0.02V drop on their voltage while run.

The timer in this circuit are able to produce 10Hz to 300Hz precise square wave, but i think the weak points are the opto couplers, because some of the 6 2n3055 transistors are get not perfect square wave in ther base when using 30Hz+ for timeing.


In the next week i will do more testing. I hope there are somebody who also built this circuit and can thell his experinece with it.

This is the first place everyone has gone to see how a tesla switch was introduced. THE TESLA SWITCH

[Matthew Jones]

So instead of using 2 resistors to drive the base use this:



The capacitor with the negative only needs to be 1 UF 10 volt or so. This helps drain the base quiker.

John Bedini showd us this back about page 13 - 35 i think. You would have to go look.

The right side, like in the picture. In around 10Hz, the sq wave input on those transistors are almost perfect, but not exactly. Raising the frequency causes the right side of the wave to get worse.


What do you mean about different driveing?

[Matthew Jones]

What side of the the wave is not square? You could drive those transistors a little different to ensure one side or the other tightens up.

hello Lamare , thank you again for the links

I thought it would interest you to know that the Moe Joe Cell also uses Electropolishing for the stainless Steel:
