Use for the Tesla Switch

I haven't put them in yet, but take a look at the ground side of test points voltage dividers.

So, the sensing only makes "sense" when battery 1 is at the same reference as battery 3 or Q1 is 'off'?

Leroy,
Bit's did answer me a few posts back. The way Q9 and Q10 are biased still doesn't make sense to me. But I was only concerned about the actual switching sequence. This sequence is a slight departure from all the other docs and schematics where the top two transistors are never on at the same time. I will try duplicating the sequence using all NPN's.

Alex,

So, in order to duplicate with NPNs, you would turn on Q1, Q10, Q9 for 800 ms, then turn off Q9 for 200 ms....right?

Yep you guessed it Leroy, however I don't want to confuse the momentum everyone is doing. I plan to put a "Rest" period in before I take the measurement.

[ldissing]

No that was an illusion. Probably the shadows. They weren't even on at max, just barley glowing. You are on the right track with the top circuits. This is the key!!!!! Once again "THIS IS THE KEY" Just like the SG, tune for the "Snap"

Bit's

Bit's,

In your setup, are both the lights more on (not fully on, but dimly on), than off. When I turned on both to Q10 and Q9 on at the same time, then turned Q9 off, as it seems you are doing, the lamps where both on most of the time, with brighter pulsing going on between them.

Yes, if the setup is correct, both bulbs will remain "glowing", however due to the cell imbalance in the batts, you'll see one pulse brighter than the other.

Okay maestro, why would that be....both bulbs on? Is it because the bottom battery on the 24 V side has a 24V potential on it from the top battery? This is very very interesting.

Your transistors do not get hot?

@JB...is this right? This would not happen in the relay version, or in any of the setups that you have described, except the two transistor version with diodes. Am I wrong in saying/asking this?

Leroy

P.S. I'm using 50W quarts bulbs, because that all I could readily obtain...for now. 4+ amps.

Tranny's do not get hot (with these small bulbs), BUT you may want to Heat sink them in prep for when you finally get this switching down to a science, as we are going to demand alot from them.

Well, depending on the length of time I leave it on at 4+ amps they certainly do. If I leave them on for 200ms, maybe my timing is crap, but they do get hot.

I don't think that your timing is crap, if you are getting +4amps you are in the ball park. Think about the sinusoidal in relation to J5 and J6 (reference my drawing). J5 sees the positive pulse when Q2 is on and the negitave pulse when Q1 is on. AC my friend. Not 60hz, not 400hz, but whatever we choose due to how we fire Q1 and Q2. What if we were to put a transformer at J5 and another at J6. Then how much load we could put on that transformer would depend on our ability control the switching and heat dispersal, plus the battery capacity.

Make sense?

Yep, I understand what you are saying.

I should have said that the serial transistors get hot at too high of an amperage, which means they need to be heat sinked or I need some more in the serial position. The top ones run very cool, not even warm.

my scope readings

Couple scope shots of the signal my commutator puts out.

My old scope picks up a huge noise field without even being hooked up when I move the probe close to the machine when it is running.

So the trace is real noisey. I am sure you could run the signal trough something to suppress the noise but I don't know how.

The first pic is a shot of the signal out of bat 2 and 4 neg.
The other one is coming out of the diodes.

Murlin, that is very chopy but I understand. Look at the first trace and draw a line from the highest peaks(pos to neg -- neg to pos). Looks like AC to me.

Yes it is the AC signal before the bridge sorry for leaving that out.
I only have side A hooked up. I haven't figured out how to use this thing yet just messing around twisting knobs trying not to blow it up...haha

I think I need to hook up side B to get the other half on DC, right? 'Cause it just shows the top signal on the bridge with just side A hooked up. But a DC wave is only half anyways.

I will figure it out, I need to download some manuals for using an ocilliscope...

Here is the circuit I am using though.

The bulb on this signal was a 3.57 volt from the Shack.

The motor that runs the switch is not powered by the load yet.

Just though I would let you all know, Scalar wave tuner is off the scale in the geo-magnetic area +100, we must be in for some huge earth movement. Last time I have see this was the Sylmar earthquake. Tuner pointing towards the south of Idaho, I'm 90 miles from Canada. Again Excellent work Bit's, we need to talk about some work we need done here.
JB

John,

Can you share the plans for the Scalar Wave Tuner?
