Use for the Tesla Switch

[Bit's-n-Bytes]

Team, here is a first cut of the proposed schematic for the "Digital Controlled TS". Please let me know if you see mistakes. John, can you let me know if I put the sensing points in the right areas?

Thanks

Jeff

Here is the first crack at the code to control the oscillations based on the measurement points. Jason, please check my work. I can't say enough about "We are going to where no man (or women) has gone before" so please understand what this code is attempting to do. Basically, if D9 is low compared to D1 plus D5 oscillations favor the firing of Q2,Q4, and Q5 to help batt3, and if D10 is low compared to D1 plus D5 oscillations favor the firing of Q1,Q3 and Q6 to help batt4. Feedback is important and objective criticism is welcomed, however if you need to get political or personal, please initiate another thread. Please use caution here.

Start:
SYMBOL D1Sense = W3 '########## Reserves buffer for D1 Value
SYMBOL D5Sense = W4 '########## Reserves buffer for D5 Value
SYMBOL D9Sense = W5 '########## Reserves buffer for D1 Value
SYMBOL D10Sense = W2 '########## Reserves buffer for D5 Value
SYMBOL TotalCompare = W1 '########## Reserves buffer D1 + D5

Main:

readadc10 0, D9Sense '########## Reads voltage at pin 17 an assign value to D9Sense
readadc10 1, D10Sense '########## Reads voltage at pin 18 an assign value to D10Sense
readadc10 6, D1Sense '########## Reads voltage at pin 15 an assign value to D1Sense
readadc10 7, D5Sense '########## Reads voltage at pin 16 an assign value to D5Sense
;let D9Sense = 8 '########## Used to debug
;let D10Sense = 12 '########## Used to debug
;let D1Sense = 1 '########## Used to debug
;let D5Sense = 10 '########## Used to debug

let TotalCompare = D1Sense + D5Sense '########## Adds value of D1 and D5


if D9Sense < TotalCompare then SwitchGroup2
if D9Sense > TotalCompare then SwitchGroup1

if D10Sense < TotalCompare then SwitchGroup1
if D10Sense > TotalCompare then SwitchGroup2
goto main

' ########## Oscillates S1, S3, & S6

SwitchGroup1:
pulsout 7,10000 ' send pulses out of pin 6
pause 20 ' pause 20 ms
pulsout 0,5000 ' send pulses out of pin 13
pause 20 ' pause 20 ms
goto Main

' ########## Oscillates S2, S4, & S5*

SwitchGroup2:
pulsout 0,10000 ' send pulses out of pin 13

LOL Is that a standard clause now days LOL.

I mean what are the supposed to say..."You right code like a liberal pink communist" LOL.. just kiddin around now

Thanks for the giggle

Thanks Matt, ROTF and LOL (I think) bit of humor as well.

Hi dambit, are you pulsing the test switch point or just continuous. Thanks.

What if !!!!!!! We do not need all these parts to do the job and only need two devices to do the whole thing? Has anybody given any thought to this? What if the SG3524 could be controlled using the error amplifier at the duty cycle pin that senses all the voltages at each battery. What other device could we use to switch the batteries since we can see that the potentials change quickly? I guess as Peter says I have been known for tricky circuits, just a little quiz. After all do we really need all the devices in the circuit to switch four batteries? By the way excellent job on the circuit diagram and the code, I can get this to run in the pic I have just a few changes.

Hi Tyson,

I just turned it on and left it. I had to turn it off a few seconds later cos the battery was charged

Cheers,

Steve.

Hello guys. Spent most of the day away from home I'm almost done building. Could probably finish within an hour or so but I can barely see and brain is switching just like my 3524 the other day
You got me puzzled with your quiz John I'll give try tomorrow, too tired.

Another successful 3 battery test

Just wanted to let you all know that I too am having much success with the 3 battery test, and Mouser is out of h11d1's (the nerve!).

On another note I have an aquaintance who runs an electronics recycling company. He has about 600 or so of the SIG SG3524D PWM IC's. Does anyone know if these are the good ones?

Leroy,
Great, say what ever you want, but watch your back as I always watch mine. If you do not want to say it on the group then say it in a private e-mail to me. I know what your talking about I have been there before you.
This thing has been on my pages forever, but no wine before it's time.
Glad I stopped by to give a little push. I'm just happy you did not give up. In my book, energy belongs to the world and all the people in it, and not owned by the few. I have never said anything I did not believe in. I can see people here I already know from other groups, but they would not listen to the instructions, this is not a debate anymore it's fact and each day more truth surfaces.
John B

Thank you for your responses. I do have the modified SG3425 circuit. Thank you for that too!

That has been my goal since I figured out what is going on. Well, I should not say "figured out", because I still do not totally understand WHY it does what it does, but I understand the "when", when it does what it does.

At higher frequencies, it provides more differential which I find interesting too. You'd think, just looking at the circuit, that you get what you can see with the diode and transistor drops, but you can get even more. So, are the batteries really at a higher potential, or are there more spikes...which manifests itself at the output?

I can get it to the point that....it looks like, well, the scalar battery charger at certain frequencies. They are one in the same really, same kind of situation going in in there.

I hope I did not say too much. That is why I asked if you wanted it posted. I could have said more, and I'm long winded anyway. Say to much and people shut down and quit reading. I know that people are still not totally ready, but Matthew is and he is doing the right things. He was the one who peaked my interest in this again with his experiments. Thank you Matthew! Matthew, if you are still in N.C., let me know. I'm in S.C. right now but moving back to Texas, unfortunately which will put me on hold for a while...in about a week. Love to get together and compare notes sometime.

Now, the biggie. You should see my crappy setup. It is the worst nightmare you could possibly imagine - and it still works. You do not need to build it with circuit boards and precision. You will get even better results with it if you do (I'm guessing), but a little bailn' wire and glue will hold the thing together and let you see it.

Guys, quit asking questions and build it. Don't ask what transistors, capacitors, batteries, loads, wire sizes, oscillators, etc. You do NOT need PWM, but it is helpful and self adjusting with micros, comparators, etc. BUT YOU DO NOT NEED PWM TO SEE IT WORK, sorry about the yelling. There is enough on JBs page and on this forum to build whatever you want. JB has posted everything you need and my diagram is just the 3 battery multiplied by 2 with one extra battery. Build it with the components shown by JB FIRST. If you don't have them, then get them. Beg, borrow, but don't steal and make it work with these components, then try other ones...I have a few ideas going through my head.

I'm finally done.

Hi Josh,

I got mine H11D3 (higher voltage) off eBay. Good supplier, tayda electronics.
They were $8 for 10 pcs with shipping. Got it in 9 buss. days to Canada.

Thanks, I have a few of the Vishay ones, but I want to use exactly what John has shown (Fairchild). Trying to take nothing for granted here.

We'd need a square wave pulsing circuit like a dual 555 timer circuit with only one active at any one time; when one turns on, the other turns off.

And we could use Zener diodes (or backwardly arranged transistors, using reverse breakdown voltages) to sense which bank of 2 batteries is at a higher voltage, and trigger the appropriate 555.

This would self regulate the charging pattern. However the load would not be 50/50 AC, so would require a bridge rectifier to some loads.

Or even the sg and commutator, which I had in mind before john joined us.
