Use for the Tesla Switch

[shadowless]

Glad the thread is coming alive again. Nice video. Are the leds in the background just indicator of the pulse? What is the cap for?

Does the duty cycle and pulse varies as well?

Cheers

Great job. Looking foward to more progress.

Bout time you started showing off bit!!!
Looks good.

Exactly like you said my friend. Jeff i dont know how you film and do all that with one hand:, your just showing off now bro I expected it to be nice but not that amazing Jeff, speechless.
THANK YOU

The "Digital" Tesla Switch v5.0b

Tesla Switch 5_0b.mpg - YouTube

Take a look. Here is the "non existent" Digital Tesla switch. Complete with terminal logging. It uses a 28x-2 chip (PIC Micro 18F2520) running at 16Mhz. (switching is much slower though). Of late, some said this was not doable. It uses transistors in a compond complex configuration, known as the Sziklai pair. In contrast to the Darlington arrangement, the Sziklai pair has one NPN and one PNP transistor, and so it is sometimes called the "complementary Darlington". Current gain is similar to that of a Darlington pair, which is the product of the gains of the two transistors. The configuration is named for its inventor George C. Sziklai. It only takes .2v to bias unlike some other switching methodolgies. Did I mention "Terminal logging" and LCD readout?" Can analog do that?

I moved my optocouplers over to my basic stamp. Right now I have it pulsing each battery independantly for 1 second and resting for 5ms before moving on to the next battery. Load is a 12.6-0-12.6 450ma transformer. The HV side is being rectified and sent back to the charge battery. The transformer is coupled to the ac output of the switch through a 1uf non polarized cap on each AC leg. I'm going to give in another hour before i take my measurements for comparison. then again in the morning.

[redeagle]

i have six MJLs driven with opto couplers. Just simple switching with a common positive between two sides. Having the common positive allows to feed back an auxilary charge into the system to bring the batteries back up after draining them trying to power a load. Can be nearly any charge current suitable to charge the batteries. Charging them back up now then i'm going to try some different loads. My ultimate goal would be to power a motor/generator that keeps the system charged then ultimately upgrade components and batteries to where I can power my minibike. But don't have the resources to do that atm.

[Matthew Jones]

I know that if I add a second identical transformer in parallel that output is potentially doubled, but would the increase be large enough to make up for the difference in load on the batteries?

Unfortunately not. You have to maintain the charge in the batteries with the switching on that side.

Are you running 6 switch's to drive your batteries or what?

Matt

[redeagle]

Right now I'm using the tesla switch to drive the transformer directly, differen't cap values in the cap pulser and analog control. Currently I have the 24v ct version of that same transformer series driving 12v ac on the 24v output leads then rectifying the output. i can send the charge directly back into the TS but it does not keep the batteries charged over time. so i am charging a fifth battery and rotating it in. I have tried with and without capacitors on the TS ac output, the caps increase the rectified output to the cap pulser but also increase the draw from the primary bank.

I know that if I add a second identical transformer in parallel that output is potentially doubled, but would the increase be large enough to make up for the difference in load on the batteries?

A few pages back someone had mentioned running a two cap pulser or inverter two cap pulser. Have many people tried that. I know the batteries make a large determination in what loads you can draw but the idea seems worth looking into to me.

Here you go,

Enjoy

Inverter two cap pulser

A few pages back someone had mentioned running a two cap pulser or inverter two cap pulser. Have many people tried that. I know the batteries make a large determination in what loads you can draw but the idea seems worth looking into to me.

[Mario]

The slow ones work very well. 8 -10 times more out but the load capacity is not great. It takes alot of batteries. You can maintain it for long periods of time if you have a secondary input of power that gets routed to the charge batteries. I have 8 of them running at this time and last I checked they all were still putting power out. Most have 20 -30 batteries on the them of various makes. One has almost 80 batteries on it now. I am not responsible for it though I just put the switch together another local fellow has been upgrading it. It provides light and small amounts of AC at a camping area he manages. I built it for them so they didn't have to listen to a generator at the river its located on.

I have ran several SG's on the different switching setups they work very good.

Within the next couple of month I plan to release a version that will eliminate the need for SG. A corrrectly wound and switched transformer is all you need....


Sorry I didn't answer sooner I have been outa town and I am playing catch up.

Matt

Hi Matt, thanks. Yes, I know what kind of transformer you mean... . Since the setup I'm putting together is small I'll use a multistrand solid state SG which can be as high as 85-90% efficiency and low ohm. What relais switching speed would you recommend if I'm using 9Ah motorcycle batts, like a couple minutes each? Or simply switch when the voltage ramp on the batteries starts to stabilize?

Mario

[Matthew Jones]

He should need diodes.

I pointed that out to him above.

This is the TS gill is doing now. do you see any thing wrong with it ?
