totem pole driver

Hi guys !

I tested on the breadboard this circuit :

http://www.energeticforum.com/attachment.php?attachmentid=7514&stc=1&d=1295135769

And i think it must be very interesting circuit just if i knew how to
make a few final steps...

I mean, something strange is happening here, and someone should
help me a little bit to understand it...

If i connect battery positive to the top line of the schematic, and the
battery negative to the bottom line of the schematic then i could not
make this circuit to work, but if i in addition connect battery positive
after these condensers (1 uf, and 10 nf which are in parallel position),
than circuit works fine, and i can adjust with 100 K pot. draining of
the battery between 50 and 450 mAmps...

But the problem is that i do not know how to manage to get output
from this circuit ? Where is the actually output in this circuit ?

I didnt use zener diode, i just skipped that diode, nothing put instead of it !

Thanks in advance !

cikljamas, thats a totem pole Mosfet Gate driver with a fixed 50% duty cycle. The ouput is the one wire that come's from the center of the right side of the drawing, it go's from the two caps to the gate of the mosfet. It's only part of a full circuit, it's just the gate driver, and it's a complicated one. The description is there below the drawing.

Ok, I got the optoisolators and diodes that farmhand mentioned in this thread. The optocoupler is going to help a lot, looking forward to trying it. I also got a darlington optoisolator, I might use that to try and drive a lot of power with a bipolar transistor. I also got some SCRs, I think there is a relatively easy oscillator I can make with one.

Thanks Farmhand, do you maybe know where to find other part
of that circuit ?
I already made half of it, i suppose it would not be such a problem
if i made another half of it ?

What is your general opinion about that totem pole mosfet gate driver ?

Cheers !

There is no other part, it's just a driver circuit, you can use it in a circuit that needs a mosfet driver with a frequency of 200 to 400 Kz at 50% duty, I have no idea what kind of circuit would use that but you might want to be very carefull with it.

Farmhand, this circuit is desulfator, and i found it in one chapter that
speaks about different kind of desulfators, i just could not figure out
and i still cant where is the output ?

And i would like to know where is the output in order to use this
circuit as a charger since your 4001 desulfator is nice charger too...

I already made another one (cikljamas improved,remember?)with
555 timer, much simpler one with P type mosfet and this one works
similar like this TOTEM one, i could not figure out where is the output
in that circuit too, but since i used it as another part of that seems to
be OU stuff together with your 4001 desulfator i did not care much
about it in that particular moment, but now i am interested to figure
out how to use these both circuit as chargers too, not just as desulfators...

Maybe there is some reason for not to be easy to adjust these circuits to
be chargers, but is it possible that these circuits are not composed
(input/output) in standard way, i mean maybe in these kind of circuits
we can not identify specific point where we could connect diode and lead current towards another battery positive as we could do with your 4001 desulfator ?

I recall you once said how you have whole bunch of different kind of
desulfators, so i thought you are right person for these questions, and
i still think you are, am i right ?

I am surprised that i can not detect output points of these circuits, but
i just cant, i tried to put diodes to the points where it should be the
greatest probability that current goes out or return in some kind of loop
to the same battery, but it did not work, my other (output) meter just
did not show any amperage and now what else i could do except ask
others who are wiling to help if they knew the answer, of course, and
if not, we could still ask Watkykjy, could not we ?

Cheers !

Hi cikljamas, That circuit really is just an "example" of a totem pole MosFET driver.

Desulfator Variations and Examples

On this page it's the first of the Totem pole MosFET driver "examples". Don't you notice the circuit only has a very small capacitance and no inductors, it doesn't have the ability to output enough voltage and power to do anything much except drive the gate of a mosfet in a bigger circuit.

This particular drawing and some others are just shown by the author of the page as examples, of driver circuits. If you look at the drawing right above it you can that one has inductors, large caps and Mosfets, it is an example of a parallel FET "charger desulfator", many of the circuits on that page are untested and are only meant as helpfull examples. If you scroll down you can see there are another two white papers with other examples of how to drive mosfets. And further down still is a pulse amplifier, it's not a desulfator either.

You can design a circuit to use it with fairly easily, but all it can do on it's own is put out pulses the same as any other mosfet driver circuit.

power

Ok, I got the optoisolators and diodes that farmhand mentioned in this thread. The optocoupler is going to help a lot, looking forward to trying it. I also got a darlington optoisolator, I might use that to try and drive a lot of power with a bipolar transistor. I also got some SCRs, I think there is a relatively easy oscillator I can make with one.

I'm not sure any particular opto is going to allow you to get any more power out of a bipolar. They can only pass so much current per their rating.

Thanks Farmhand !

I thought that this totem pole circuit is self sustained (no needing
inductor), and i thought that even more because i had same value
readings while testing with meter this pole circuit without inductor
and that one 555 with inductor...
But it seems that you suggest that this one also need in addition
at least inductor to be functional...

Never mind, i wont bother you any more about this subject since
your last answer was so clear and complete that i just have to
be completely content with it, and i am of course !

So, thanks once more for your patience with my so often beginners
and inadequate questions !

Cheers !

[Farmhand]

No probs cikljamas, Every day we all learn something new. It all helps in the long run, you help me, I help you. I don't mind at all, i'm sorry if the way I write seems a bit funny. But I have trouble trying to explain things I only just worked out by chance myself.

I didn't get the opportunity to go to town today for the inverter parts. Did you try one of your transformer windings reversed to make it a 9 0 -9 transformer, with your inverter ?

I'm basically sitting here tapping my finger nails into my fingers waiting for something to come in the mail. I just hope all of it didn't get washed out to sea in the floods. I'll have quite a wait to find out what is coming and what isn't.

Oh well i'll get some stuff tomorrow from town I hope.

Cheers

[Farmhand]

Yippee, some stuff came, I got my nano scope, inductance meter and a box of componants, I forgot what I ordered, but I have 12v regulators, op-amps, 4011 chips a couple of IRFZ46N Fet's, some tiny caps and some normal 1mm magnet wire.

I measured my serial pancake and it has a negative inductance -4uH, And my serial conical is -8uH What does that mean ?

My new very small desulfator coils are 60uH they should be 200 at least, the first one I made is 268uH which is good enough, the core material must be very different type of iron powder.

This nano is difficult to understand but i'm getting there, hopefully later I can measure the shortest on time I can get.

Cheers

P.S. Couple of shots attached. What do they mean ? Except that I havn't worked out how to use it properly. The PWM pulses are a bit slopey but it doesn't seem to have too much effect on the recovery waveform. All these settings are confusing.

Hey Greg, have you cut up your primary yet, cause I was thinking maybe you could wind one primary winding correct turns, without cutting the wire then leaving a bit extra you could cut that one unwind it and use it for measuring the other two against. Gee wizz, I should have thought of that before, there could be left over wire like you said.

[cikljamas]

Glad to hear your stuff came after all !
Now problems in Victoria state ? How come New South Walles
stayed untouched ?

No i did not make my transformer, and i have not intended to do such thing
so soon...

But something else i hesitate for certain amount of time to open as a theme here, and now when it seems your conversation in "this is it" subject slowed down recently maybe i could tell you what is on my mind : HHO !

Greg has big experience with that, and few months ago i printed certain
pdf file (firs 100 or so pages ), it is about EFIE , and other electronics that
is necessary to be implement in car together with joe cell, and after winter
i am planing to bite this stuff as a crocodile since prices of gasoline just
jump as kangaroo here, now one litre is 1,5 $...Mother "#$%ers !!!

So, maybe in Australia and America is a little bit better situation than
here but i think your guys over there would like to drive your car in
Stan Mayers manner too...

So, Farmhand where are your thoughts concerning this problematic ?
I mean, HHO (in Croatia this acronym goes for Croatian Helsinki committee
so no one could say i mean something else by this than that )is
something that we could make following instructions and regarding this
fact it is closer and much more realistic than "this is it" theme which is
interesting and desirable subject but seems to me just too far away from
us and it is going to take who knows how much of our (Yours) precious
time to be accomplished....And confute me if i am wrong, but i think that
time is money !

Do not get these words wrong, i am not discouraged in this Watkjyky stuff
too, but even if you made it (and it would be as dream come true )HHO is
still waiting to be made as inevitable project for every one of us who seek
cost cutting of our gasoline bills...

Maybe we need new thread about this ?

Cheers !

[Farmhand]

Hho

Hi cikljamas, I made some HHO a while ago and it's a bit dangerous if you ask me, in the car would be OK I guess. I wasn't very carefull with it. I put the HHO through a bubbler and blew up a latex glove with it. Then I poped the cap of the bubbler (a detergent bottle with small hole in the cap) and as I lit it I squeezed the glove. Bang the whole cap blew off the top and smashed on the cieling. Everyone hit the deck and all our ears rang for a while. It worked much the same as an Oxy-Acetelene ballon. Instantanious incineration with much expansion and noise. Didn't even see a flame, it was all over too quick, no injuries except to our ears.

Anyway I don't do that anymore. But a setup in a car would be pretty good.

As for this project it's just intermission, i'm waiting on wire, when I get it my fun will start. I am going to finsh this project with Greg we already have our stuff paid for, and we have lots of idea's, after all Nikola is counting on us, or laughing at us, either way at least he won't be spinning in his grave in disgust about us. I plan on buying more cores and making some big one's too.

I hope to finish this project before May/June so I can start on some earth batteries and Van De-Graff machine for my infinity c.o.p. project. I'm actually starting to reduce my other non electronic projects so I will have more time. My time has nothing to do with money i'm very fortunate that I don't need much money, I only use it because I have to, I don't want to, but the electronic store won't accept eggs and meat as payment or veges either, don't know why, they mustn't eat.

Greg will be able to give a better opinion on HHO than me not sure if he likes hydroxy but he like's to say HHO so i'm sure he'll be happy for the opportunity to type HHO a few time's.

I must admit cikljamas, I get a smile or a laugh out of most of your posts. Your a funny and cheerful guy, but serious too.

With any luck the mail is flowing fast now and my wire will be here soon. Wish it God Speed for me. It might arrive quicker. Oh and by the way I don't drink alcohol I gave it up a long time ago, the bottles you might notice in my vids are home made stuff in normal bottles, for the visitors.

Can I put a HHO kit on my 100cc farm bike ? 20 litres of fuel lasts me for months.

Cheers.

Farmhand, awesome scope shots, thanks! It looks like you have a non standard firmware. Since it's open source there are forks. I have heard of that branch of the code, I should install it and see how it's different... Looks pretty nice...


Greg, are you going to clue me in on which technology you are planning on using for the new impulser? I'd love to start learning about it.

Thanks

[Farmhand]

7imix, it's version " 1.5.20p " yeah it's pretty good, once I got the hang of it a bit. Pretty screen, still having trouble with the offset I think, if I post shots and you can see where i'm going wrong be sure and tell me. I don't get offended, well not for long anyway. It was about 6 % duty, I can't decifer a time out of those shots. Might take a few go's to work that out. Anyway but when I strech out the gate pulses they are not all that straight up and down.

But the recovery waveform is fairly straight. Wierd. I'd like to be able to get some rise and fall times if I can somehow, on the gate pulses, to compare drivers. Next time I go to town i'll get some 330 ohm resistors for the opto's. And those 4047 chips for an inverter.

Have you measured negative inductance like i did, on a pancake ? negative 8 uH That still has me puzzled. No idea what to make of that.
