Solid State Bedini

[Sephiroth]

hey mart... how many transistors are you using? If you use multiple transistors in parellel (about 10 should do it ) it should bring the current through each componant back to a "normal" level... never tried multiple transistors on a single strand before but it should work.

[theremart]

What is my setup.

lol... you seem to be attracting electrical fires Mart! Play safe

Do you know the rpm you have with the new coil? and number of magnets on the rotor

I did not test rpm I am guessing about 6 - 700 rpm. magnets 4 monster neos.

160lb pull.

[theremart]

well...

I do have both of the speaker wires tied together in parallel .... Think I will try it with only one

[theremart]

Ok..

Went to the 2n3055 not as much kick, but very stable at 24V. Both target batteries rose to 13.25 from 12.89 in 15 min. Think I will hunt down another one of the transistors I had before and try that again.

Monday hope to do more tests if it is stable I will post a video soon.

F. me, I just spent the last 15 mins. typing out a reply only to accidentally press the 'back' button.

Anyway Mart, what kind of load are you able to get from your batteries with such short charging? I've found standing voltages produced this way can be misleading.

Hi all,

Jetijs, I am wondering if the wave that is produced from this solid state method is as effective as the "h-wave" seen on other solid state setups. I have notice that on small general batteries it works perfectly, but on larger batteries (car batteries etc) it takes quite a while to reach a decent voltage. (compared to the non solid state setup).

Last night I discharged a car battery I have at 2 amps for 9 hrs 40min. After 2 hours rest it was sitting at 12.41V (not bad for a battery that was to be tossed out last month ). I have been charging the battery for 7 hrs now with my 5 transistor coil at a fairly high draw, but not much above normal. The battery has only just reached 13.04V. I will let it go until it will not go any more, and then repeat the process. Only the next charge will be with my regular magnet setup. Should be a good comparison of the two wave types and there effectiveness.

Cheers,

Steve.

RE: Charging.

You are correct about being misleading.... I don't know for how long I could sustain this charging rate. Monday I do hope to do more tests with the 2n3055. However for the batteries to stay up to 12.30 under a 2 amp load is impressive to me. Yes I am way over the c20 rating of the battery, but it sure was fun lol

I thought about it some more, and the batteries that were charged were on the solid state charger for about 2 days. before where they reached a top voltage of 15.3 V. It seems from past experience that directly after I use the solid state charger, and put the batter on a wheel charger the top voltage goes up higher. So when they went up to 17V this could be simply because the battery was in great shape to receive charge. But... two of the batteries were not on the SS charger and they went up to 14V as I recall, which is still very impressive to me.

I could not sustain this charging, I looked at the data sheet for my transistor and it says the max amps is 1.5 amps peak for my transistor. So it is no wonder that I cooked it.

Hi teve
I have not hooked up a scope to see the wave, but I will do that. My batteries are charging up higher one each charging cycle. For example, on the fourth charging cycle, the battery went up to 14.01V but on the fifth charge cycle it already reached 14.11V And it's getting better and better. Also the tested capacity increased bit by bit after each cycle
Good luck!

Ok, here is a waveform on one of my transistors (across emitter and collector). The charging battery is attached.



That little spike that you can see, is probably there because the battery is not in the best shape yet and can not absorb all the radiant spike. I have no good batteries around (they all are in use) to test if a good battery will have a smaller spike. Anyway, the waveform looks good, the classical h form

[Shamus]

Just for fun (and you guys messing around with higher amp draw) I decided to lower the ohms on my triggers on the 4PMP (OK, it's not SS, so slightly off-topic) from 1K down to 390. The amp draw doubled (from 390mA to 800mA) and it seemed to push batteries up quite quickly. My gel cells which usually take a long time to get over 13V shot up to well over 16V and stood at around 12.8V after ~20 minutes of charging. Of course when I loaded them up, the voltage sank like a stone down to 12.4V (my usual load termination voltage) in a matter of seconds.

I did do a few tests with a six hour charge time and the load times were longer but seemed to be proportional to the charging I got at the lower amp draw. There's still some surprises here it would seem.

At any rate, I keep coming back to the idea that every drawing that John Bedini has put out shows at least two batteries on the charging side connected in parallel. Which, as I'm just now coming to realize, changes the impedance of the system. Then again, John has said that the machine doesn't care if there's one battery on the back end or four and I can't help but wonder why nobody has reported any success replicating this phenomenon. I would do it with my two 7Ah gel cells but one is damaged from overzealous load testing on my part. Perhaps it's time to bite the bullet and buy a few identical tractor batteries.

The other thing I notice is that the back end batteries on those drawings don't have any diodes to prevent backflow from one battery leaking into its paralleled neighbor. This would imply that the batteries are well matched to each other and in similar condition. So much to think about.

At any rate, this long winded message is really about impedance (doesn't it always come back to impedance? ) since I noticed that my 1000 MCA battery seems to respond better to the lower trigger resistance/higher amp draw--again, it seems to point to impedance as being a critical factor to success with the machine. I'm still struggling to understand it all, though, since John says it's the spike and not current that does the charging (and putting a 1 ohm resistor in the charge position and measuring the voltage drop and current through it seems to bear this out). But somehow pushing more current through the coil does something to the charging--creates higher spikes? I don't know since I don't have an oscilloscope to measure such things. It seems counterintuitive since you don't need a lot of current to get the spike, just a fast off switching.

Much to ponder.

Bedini Patent on SS methods

Circuits and related methods for ... - Google Patents

The above patent is well worth looking at.

Maybe it will resolve the page 46 FEG circuit objections.

[Shamus]

Actually, I thought I addressed that elephant in the room already. But just in case that wasn't enough, I believe you're talking about figure 4 on sheet 2 of that particular patent application.

Yeah, I don't understand the ferocity of some people to revealing the information on that page--after all, it's an idea and ideas are easily shared. *shrug*

Hi Jetijs,

Is that running on 12V?

You are right, that is a "h", and that is the same wave that I get, but I thought the one in the dvd was the shape we are after.

Cheers,

Steve.

[Jetijs]

Hi Steve
Yes, that waveform is when running at 12v.
What do you mean with the "waveform from the dvd" ? What should it look like?

[ren]

Dambit, I think you may be reffering to the cap pulsers waveform, as seen in the FEG book. The "H" wave form is the waveform the coil produces. The cap pulser waveform looks a little different. Specify which waveform you are reffering to.

Jet, does the SS setup you have there charge like the SG? Or is it collected into a cap before it returns to the battery?

Thats still quite a spike with the battery attached, my spike almost disappears when the charging battery is attached... YOu may be right about it being related to the condition of the battery. Interesting to see if the spike changes at all as your batteries get better
