One other thing I would suggest is putting an on/off switch between your stamp and its power supply. If things go South you want to be able to kill the power quick.

The STAMP runs off of a 9 volt battery, or you can hook it to an isolated 12 volt battery as Matt has discussed. If you use the 9 volt you STLL have to have a 12 volt power supply to run your board. If you purchase a snap on battery connector that will snap on where the 9 volt battery was supposed to go, REMEMBER that the RED wire coming off that snap on connector goes to GROUND and the BLACK wire goes to POWER. That connector is made for snapping onto a battery, not IN PLACE of a battery. Look at it carefully and you will see what I mean.

Where the resister connects to the 3120 there was no trace, and since it is such a small gap, I bent the end of the resister over and soldered it to the 3120 to make sure there was a complete circuit, which eliminated the NEED for a trace there. They are so close you could almost solder them together if you are careful (if you have already cut them off) My terminals also did not want to fit into the holes, but I solved that problem by laying the board on a piece of soft wood, placing a block of wood on the terminal, and tapping on it gently until it went in. It was a tight fit, but it went. Once they were in there was a connection to the resister, I checked with a meter. SO I didn't have any soldering to do there. I would advise you to check the back of your board to see if all the resisters connect to the 3120's. There was a trace on the first one, but not the rest.

Sorry about that Dave , doing or learning things are always not free .and blowing up things thatís what I do every day and thatís how learn arenít we?
And thank you for the information.

Hi Matt

Thank you for the codes
I will try to read your explanation more to understand what is going on in this setup hope I will not blow up things this time.
I did the jumper you mentioned and did finished winding my transformer and by the way itís not 250w its 75 w but any way I wind 8 wires #23AWG 12m but I did one mistake in my order ,I order for 3 fast diodes instead of 4 and I have more than 40 diodes of the same diodes I use in your tesla switch they are Digi-Key - FFPF15UP20STTU-ND each one is 200v 15A can I used 4 of them in parallel instead of one diode of these (RURG5060-ND)?
When I check these diodes ( FFPF15UP20STTU-ND ) in Digi-Key now they are using the same diodes with three pins not two pins the one I have with the same part number.

Ya those diodes should be a problem.

If you need any more explanation let me know.

Hi Matt

I orderd for one ultra fast diode but this one is 600v 70A not 50A llike the other three wouldn't that be a problem or it is ok because if I will by the the same diode from Digi key it will coast me 40$ so I bought this one for 15$ less than half price.

Ya thats fine. You could use those diodes you listed earlier. Your not going to exceed 15 amp

But either way that one will work.

c1 d2

Matthew
Please help me here I do not understand how C1 can discharge through F3 when
D2 is blocking it's + path to P1. Would it not work like this instead?

Either my problem wasn't that I blew the series fet, or I just blew another one instantly, because I replaced it and am still having the same problem. I may not get back to this until Monday morning, because I have a full day scheduled tomorrow. Will check every connection on the thing to make sure all is well and then try running it again, and THEN begin the process of looking for voltage at various places in the circuit to see what is going on and where the failure point is.

It was running great until I put in the new program, but I didn't even run it before deciding to run the test program again and get exact voltage measurements, so I don't know what I changed that could have messed it up, unless I entered the program incorrectly

F3 discharges C1. D2 is in place to straighten the AC out. F2 Discharges C2.

Unhook L1 and L4. You most likely blew another fet instantly. You have 100 volt fets and you might have 350 volt spikes coming off of those 2 windings.

I gotta fix for it I think but I trying to get mine setup so I can see first hand.

Also test the fets with light bulb and regular circuit and see of they are open. I'll draw something and post it for testing fets.

Matt,
There is an unused DC to DC converter on our boards. Couldn't we hook direct to that from say pin 5 on the Stamp and run a program to light a bulb using the fets? That would give us a reasonable test and all we would have to do is disconnect the four wires from an existing fet and hook up some new ones.

Dave

Ya.

Just come out of the hot on the battery go through a bulb. The from the bulb to the Drain of the Fet. Then go from the source to the ground of the batt.

Now hook up the driver board and run a program like this.

' {$STAMP BS2}
' {$PBASIC 2.5}

DO
HIGH 5
PAUSE 1000
LOW 5
PAUSE 200
LOOP

That will run a bulb and make it blink once a second.

Then you'll know if the FET is ok.

If you go to hook it up and the bulb comes on without the code running your fet is bad.


Do not hook up any more Fets David just leave it alone I'll have a solution by tonight.

I can't help but think my problem is other than the high voltage spikes. I never saw more than about 48 volts in the cap and I ran the test program about five times before the problem started, charging and discharging the caps. If the fet could stand up to 100 volt pulses and the cap holds more than 100 volts, if the fet was getting hit with voltage over 100 volts wouldn't you expect to see at least 100 volt in the caps??

I'll see if I can't get down there this morning while the wife is still asleep and at least test the fets and see if that was the problem before we head out for the day. It's only 5:30 so I should have a few minutes.

Dave

I was wrong. All three fetts are dead It might still be that somehow I have something wired wrong. I will go back through all the wiring, and I definitely won't hook up anymore fets. None of the lights came on when I made the connections, but none of them came on when I ran the program either. So to be SURE, I need to measure voltage coming out of my DC to DC converters and make sure 12 in and 15 out. I will do that right now and post in a few minutes. Maybe THEY are blown instead of the fetts. That's what blew on my first board...all four of them, even though one wasn't being used.

OK...The DC to DC converters are A-OK, so it is either the fetts or my wiring. I will eliminate one possibility sometime today or first thing in the morning for sure. I have checked the wiring a couple times already but third time is the charm.

And maybe I need to be looking st some different fets?

No the spikes are 350 - 500 volt more than likely. So the fet takes the abuse a few times then gives up. More than likely it will decide not to work after you shut it down as opposed to while its running.

I'm here working on mine. Thought i'd be out all day, but have a bee swarm in the back yard and can't leave the dogs out in THAT. I can sneak into the basement and hope they don't come after me...since it has only an outside entrance.

Thanks. Yes I do understand that D2 is in place to straighten the ac out.
C1 if it is going to discharge into P1 and P2 by F3 then it needs a UNBLOCKED + path to P1 + and D2 is blocking it's path to the + of P1 so no power can flow out of C1 - by F3 because C1's + is blocked by D2 and there is no other path for C1 + to P1 + the way you have it, unless I am missing something

I see now what your talking about. Your right.

MAKE A NOTE WE CHANGED THE WIRING AROUND D2

One more thing now that C1 and C2 have a + path to P1 and P2 the protection
diodes on F1 F2, and F3 represent a dead short across F1 F2 and F3 because the direction they are trend will let the - of C1 and C2 flow back through to the + of C1 and C2 when the transformer tries to charge C1 and C2 the power will flow back through the protection diodes on the Fets. The current will be to much for them and thy will blow out then on the next switching cycle of each Fet they will be blown out because they will no longer have the diode to protect them from transient spikes. I know reverse diode's like this will blow because Steve and I did it on a four battery TS. I hope this helps
What do you think?

If you set it up so that F2 and F3 can run in the opposite direction then I think it should work . Please correct me if I am wrong.

Ya you might be right. My caps aren't charging. No major damage will happen though. I'll turn them on mine and see if it helps. The caps aren't charging but they are old and I thought they may have gone bad.

Good news though...

Even without the cap dumper my bulb is lit. I have 12v battery charging at 14.20 volt and the primaries have been slowly coming back up.

I'll report more this evening.

UPDATE

I have made changes to the original schematic at F2 and F3, also at D2 we moved a wire. Also Added a 1kv .01 uf capacitor across the drain and source of F1. And Added a 600 v 10 amp diode across the drain and source for further protection.

MAKE SURE TO USE THIS SCHEMATIC!!!!



Cheers
Matt

OK so I got this thing running but I screwed up a bit and didn't pay attention to the impedance on my windings. I have got .6 ohms on my primaries. I should have used a bigger wire. The results of having more than .1 are you get voltage divider on the pulse so everyone should note how much resistance they have on the windings.,

Anyway I'll rewind it and fix it, soon as I can.

If someone is following this thread and is not doing the experiment but still want to help you could compile all the latest data so everything up to date can be found in one place.

This thing will work, I am already seeing it. It will take some time and patience to get some bigger loads out of it but what else do we have to do.

Cheers

Hi Matt

Thank you for the update but a couple questions these 1kv 0.01 uf capacitor and 600 v 10 amp diode are any or there is a special one I mean the capacitor can I use ceramic and also the diode is ultra-fast or normal diode just 600v 10A?
And about the transformer I am using now #23AWG shall I go with thicker wire or I will stick with this gauge after what happened to your transformer?

Well you have seen it first hand. This one does the same thing but it is slightly less powerful and alot more controllable. I have several times now been able to make it work correctly with other circuits, I know this one is worth going after even if the load is not so big.

The diodes can be Ufast but it doesn't matter just high voltage is really what your looking for 2 amp is good enough. Thats just aa diode I had on hand. The cap is ceramic .1uf.
Both are probably not needed with most smaller setups but it won't hurt to have them.

Just measure the resistance of your wire. If its over .1 ohm you probably should do something bigger.

Hi Matt

My wire resistance is 1.6 ohm so I have to unwind the transformer and get a bigger wire maybe #20AWG but in this case I want be able to wind 12m long so what should I do?

Hi Matt

1.6 ohm is the resistance of one wire and the resistance of the 8 wires is 0.6 ohm so I don't know which one you mean?
