Bedini solid state oscillator and Tesla switch combination

[Guruji]

Working

Yes I managed to make this circuit work at last
I think the problem was the pot not the lenght of the coils cause I used my original bedini circuit which is about 6ohms on pulse coil.
My pot was 1k and now changed it to 4.7k. When I turned it high up it began oscillation.
Voltage have risen very fast I noticed on charge batteries. Should see charge batteries hold the charge now when they reach the right voltage.
Thanks to all that tried to help.

There were 3 300cca (42)ah and 1 -18 ah. 12v side was 12.66 and 24.4v on the source side with the switch open. source 2x 300cca charge 1-18 & 1-300cca. Will start the switch closed today Doug

Any results on switch closed 49er?
Thanks

Hi Guruji

The switch closed, I didn't like it used up too many batteries before it charged the ones that I first put on. But the switch open I have had good luck with that one, just haven't posted yet. I wanted to get more data first. The one thing I can tell you the closer you match the batteries in amp hours the better you can see the balance of the power.

The more I work with this design I believe it is not a Tesla switch but a Oscillation circuit. Still trying to figure the 24v over 12v but I do know it is working very well. I am working with bigger batteries T105's know and waiting for the end of the first half and do a flip. I also have set the frequency to 3.5Hz when charging so no mater what amps go in at least the frequency is the same.

Hi mbrownn and all

First test with T105's with switch open

Start run voltage 26.4 (13.3 & 13.1) charge voltage 12.36
It ran 91 hrs. this is bifiler litz 18awg Air coil with 2n3055 1-1n4001 1-1n5408 and had 177 ohms on the trigger drawing .730MA
End run voltage 24.1 (12.1 & 12.0) charge voltage 13.77
now to do the turn around and start over. I think this work's great to desulfate batteries.

Hi 49er interesting results. What if you used the normal SSG would it be with same results? One should check about the difference of the two setups.
Thanks for sharing.

Sounds great!
Did you also try this one (the one to the right)?



Two batteries in series to drive it, and the rest in parallel charging.

This seems similar to a Tesla switch. Hm... a bit odd. It looks backward to me. I've done some analysis with capacitors and saw that energy and charge can be interchange to get one more than the other by changing capacitance.

Let's say you have 2 capacitors at 1F and 1V.
In series you have 1/2F 2 volts. q= CV = 1 . Energy E = 1/2CV^2 = 1
In parallel you have 2F 1 volt. q = CV = 2 . Energy E = 1/2CV^2 = 1

If q is the amount of discharge from cap/battery, why would we want to connect them in series. According to this, if total q is the current flow in the circuit and conserved, wouldn't we want to charge in series?

Overall, I think the correct set up is discharge in parallel, charge in series.

There is something going on to this circuit ; charging gets up fast. I want to see if I manage to charge four batteries to themselves. This is would be a great achievment. Fingers crossed.

Hi mbrownn and All

The second installment to the TS . Start voltage run 25.6 and charge 12.14 volts with 3.5 Hz and .7 ma. It ran 157 hrs and the end run 23.7 charge 13.57 volts. Do we need more info , I have started round 2 same set of batteries but it looks to me as we are not gaining in voltage or capacity.

Once you have the batteries all performing well we can do the real tests.

Calculate the total energy used to charge the batteries, then measure the total energy that has to be drawn out of the batteries to bring them back down. The best results will be at a C20 charge or discharge rate. Divide the first figure by the second and you have the COP. There is no point doing this with defective batteries as the COP will be always low.

Are the inductors connected, as in a Joule thief circuit, or are they independent? I admit I don't understand this circuit really -- can someone please show a photo of their recent set-up? That would help us trying to learn.
And -- best wishes for your success!

Hi Muon,

I think the joule thief circuit is good. My argument is we should connect a bunch of batteries in series to charge, the more the better and use high voltage from collapsing field for charging.

Thanks

Well and succinctly put, quantum-- and I agree. This seems to be a KEY idea, I agree -- to collect the "high voltage from collapsing field for charging". A good summary.

Hi folks, Hi quantum, are you saying to still use the tesla switch type method, where we say use 24 volt, 2 - 12 volt in series charging 12 volt, 2 - 12 volt in parallel and then we use the collapsing field of coil to charge multiple 12 volt batteries in series.
Or are you saying to try, say a 12 volt battery for input and charge many 12 volt batteries in series from single diode flyback charge.
I thought I have tried that in past, though maybe the batteries would need to be smaller amp hour capacity for the charging end and then use many of those in series to equal same watt hour equivalent of the larger 12 volt input battery.

For example, If we used a 12 volt-7 amp/hour input battery and if we were to use say 1.2 volt AA rechargeable cells for flyback charging, we would need around 35 AA's in series to equal similar watt/hour energy capability as that of the input battery.
What you are saying makes much sense quantum, i guess we just have to test this out and see how it performs.
The reason I mention lower capacity cells in the charge position, is because I seem to recall from past experiments, that putting a bunch of equal capacity, in this case, 12 volt-7 amp/hour batteries in the series charging position, they do not charge well, probably because that load requires too much current, which the collapsing coil field does not contain.
Though using lower capacity cells for charging, just might enable us to charge those efficiently with the low current flyback charge, whether or not we use the tesla switch type method or not.
Hope this helps and your thoughts appreciated and I will be testing this in some form.

Hi Sky,

The extreme of my thought would be using a 1.2V battery providing energy and several batteries in series for charging. Using high voltage charging means you won't get much current flow through, but I think the trade back is many batteries charge at the same time. Frequency maybe use to accelerate the process. The voltage depends on the rate of current collapse so may need as low on time as possible and open it as fast/clean as possible. I think the key here is to suppress input current and only use its rate of change. Still trying to do some experiment to see if this is valid. Thank you.

this is something i do now , using SSG circuit i am not sure what is charging it but definitely it works... and i change the frequency just by hearing it out..

I ran it 2 times overnight, now both times successful.

I checked today morning out of 7 batteries , the 3 small ones are all charged and 5 big ones are charged , the rest 2 are i think done for their life ..i mean they are dead.. very impressive result..

i cannot explain the 9v battery can still cause that oscialltion sound , that means i am ready to charge more using the same almost dead battery 9v..
