Yes.
And i have done it in several setups.
Unfortunately diodes eats potential.

Here i did another test on the subject:
YouTube - Tesla-switch part 7
I will redo this test using better equipment when time permits.

Nil said...Unfortunately diodes eats potential.

Thats why have been encouraging a switching solution. Solid state relays or something low resistants. Switching also allows for a timely event.

If you use series dual shottkey diodes like the one's in PC switching power supplies you won't loose to much potential as the voltage drop over them are only about 0.2v and even less if you parallel them. The MBR3045ct diodes can handle 30A at 45V.
So with 4 caps you will only loose 0.6v in series and it looks like 0.4V in parallel.
This is what I thought the circuit can look like.

Cap diode Series to parallel switch

I put together 2 caps and 3 diodes to test this principle this morning and it does indeed works like that. I charged them with 2 batteries to 24v and when you remove the batteries , you measure 12v over the cap ready to be dumped to a load. A nice little current doubler.

Whats the input / output ratio like?

It was just a manual test to see how it works. Only measured voltge.
I ordered a panel ammeter and will test as soon as I installed the diodes into my relay cap setup.
I'm sure you can use Shottkey diodes in your capacitor bank instead of relays. Much easier to test with anyway.

[nvisser]

It looks like it is working as expected.
I made a few changes on the circuit.
The cap over the relay coil are 47uf to keep the relay closer for a shorter time, otherwise the 470uf on the input side charge up to high and cause problems.
I only used 4 x 15 000uf caps. When in series they are only 3750uF and they charge up very quickly to about 75V when the relay switch and dump the then parallel caps (60 000uF) with about 18V to the batteries.
It dumps twice every second.
The 4 parallel batteries that were full from previous tests ,resting voltage were 13.45V and after pulsing for 30 sec the surface voltage over them went up to 15.5v.
I would only love to know what the current pulses are as I am still waiting for my panel ammeter. When the wire from the battery terminals came loose it made a large spike.
The relay does not spark at all with the faster switching.
I must say that the inputs to the SSG and joule thief that drives this charger are 24V as I needed good radiant pulses to charge this caps up fast enough.
I am not going to leave it on overnight. To scared that something will go wrong.
Here is the latest diagram
Thank you Hob for the diode circuit idea!!

Howdy.

It sounds like its been determined that there is a SS SG or similar on the input being used as the source to charge up the two caps (or however many) in series and then discharge them in parallel into the battery or load.

I finally got the pin header installed and made the cable for the additional transistor arrays and I've rigged the system to charge in parallel two caps and then discharge these two caps in series into a battery as load.

Input shows 2.4amp pulses... output shows 1.2amp pulses... there is pretty much always a 2:1 constant between input amp readings on the analog ammeter and output amp readings from the same analog ammeter.

To go it the reverse and charge in series discharge in parallel the only way to get above the load charge battery at 12volts is to push a minimum of ~13volts into each cap, more like 15volts if you account for losses in junctions of the semiconductors perhaps. This means that at two caps in series you have to reach a peak charge volts of at least 30 volts. For four caps all in series its at least 60 volts. etc.

This can't be done with 18volts and 3amps "direct" from the DC supply source without doing some switching or SS SG type front end on the system. The one method was to take the 18volts and make an initial stage where you charge two caps in parallel with 18volts then put them in series to discharge into the two caps that are in series on stage 2 to be charged to the 36volts-ish, which then are put back in parallel and discharged into the charge battery at 18volts. However if C1/C2 in stage one are say 10,000uF, and C3/C4 in stage two are also 10,000uF, what was the difference of just isolating the parallel charge into the first pair of caps to then discharge to load directly? The only way I can see that as being functional would be if the stage 1 caps were like 10,000uF and the stage 2 caps were 1,000,000uF and the voltage passed forward was retained and not adjusted to more current and less volts due the skew in capacity. Unless someone has logic or benching that shows this latter skew works, I don't know how it could and thus haven't tried it.

The SS SG tho, that could be used to charge up the source caps in series to whatever target voltage... the only variable then is time taken to reach that voltage which is dependant on how the SS SG is laid out and how much current density/power is behind it. Really the SS Sg or some variant is the only way I can see that the series placed caps can get to a voltage higher than the charge batteries own voltage causing a current to flow into the battery, since at 18vdc source into two caps in series ends up being 9 volts in parallel in each cap. Just not gonna cut it. (unless I'm not understanding the goal properly, perhaps we want the inverse charge to press back upon the caps? I dunno... )

Is there any chance the capacitors internal resistance might be part of the issue here too in terms of matching impedances of the internal resistance of the battery to the internal resistance of the capacitor?

Take it easy,

Thank you Hob for the diode circuit idea!!

My intention with the S/P-caps was to spike them directly from a coil,
but you might have found another use for them,
i don't know, cool anyway.

What about the P/S-coils?

/Hob

[nvisser]

They are spiked from a ssg coil.
Iwill still look into the diagram of the P-S coil

You forgot the key element to the SSSG is that it is driven by a Tesla Switch.

This is what allow the ratio's of input out to go up. You can run a monopole on a Tesla switch and the COP of the machine goes through the roof. I do not think a SSSG or Joule thief type circuit would be any different.

I have run 1/2 farad caps in a Tesla switch and watched them run a 250 watts motor/load for 3 minutes on there own.
Thats good extension of the potential energy.

well said matt. Everyone keeps saying they can't quite get the a) tesla switch b) scalar charger c) SSG working. But i've yet to hear someone saying they combined all three and still can't get it to work.

I am sure Nvisser will get there soon. I want to set one up but I got much going on.

YouTube - ISCC_Running.MPG, May still be processing.
This switch has turned pretty good but it is doing weird stuff. One of which I whenever I go to run the motor it shuts the camera off.
4 attempts to complete the video and the same thing happened everytime.
I think its zapping the acyline's in the camera. It the weirdest thing I have ever seen, but I seen it 3 times now. Go figure.

TS powering SS SG.

Has anyone actually done what you note? I've run a mechanical SG using a static layout of the "tesla switch" principle of relative charge and that lets you charge the normal bedini charge battery as well as it charges the parallel stack acting as the low side of the potential being applied to the SG. I've not yet built the "switching tesla switch" to use that to power the Mechanical SG. (or SS SG).

The gain noted will be on two different banks of batteries... there is the normal bedini charge bank of batteries and then there will be the parallel stack of batteries acting as the low side potential from the relative charge on the staticly wired tesla switch layout.

Its not a big stretch for me to merge the actual switching tesla switch as the source to a mechanical SG I have so I will maybe look at that going forward as I've not yet managed to get decent results with the replica of the bedini solar charger attempt I'd built out.

Were you able to keep the system going for more than 3 minutes with your half farad caps? Any asymetry in cap charge vs. powering load?
