Bedini Capacitive Discharge Chargers

I have thought of this too

Ewhaz, I don't know why your capacitor is behaving like this, but I also have a question that someone hopefully can answer. I am going to try the cap pulser setup, but instead a scr or neon I want to use a solid state relay, driven by a 555 timer. The relay is rated for switching up to 250V and 60A. What do you think about this?

Yes, I thought of doing this too. Relays can make much better contacts and may produce better charging effects. Please tell us if you get better results.

I just got batteries to test my self oscilating circuit with but something strange happened.

After about 15 mins or so my capacitor began to overheat on the charging side. It's a 450v 3.3 uf capacitor so it should be set properly and be well within range for the unit. I'm using a Neon bulb to trigger the scr so the voltage never gets much above 55 volts in the cap.

Any one have any idea how to keep this from happening?

2 volts over and high vs. low capacitance

The 2 v over battery from the caps is a direct reading attached to the capacitors so I would have to say it is very accurate. Capacitors take out a lot of the pulsing questionability I believe.

I have used high voltage caps with low capacitance as low as 1uf and even as low as 0.1uf and 0.01uf. With these, yes the battery voltage goes up but it is TOOOOOO radiant meaning not enough current is moving the lead ions and it becomes just a fluffy electrostatic charge and not a real charge. Even though we are wanting to charge with voltage potential, there is still a voltage-potential:current ratio that we want to be idea. Too must potential and not enough current is bad...too much current and it is just a hot charge. We want the bare minimum amount of current to get the battery in real charging mode and that doesn't happen if using super low capacitance and high voltage (from my personal hands on experience).

thats the spirit splocal. I know how you feel. A part of me is yelling out to wind ten huge coils and make a 20ft, half ton rotor! Maybe its a good thing that I cant afford that kind of wire at the moment.

There are many different variations you can attempt too. I got a little window motor up and running on the Bedini/Cole circuit the other day, which was rather satisfying. The circuit is a little more complex and it took me a few go's to get it. You can have a few projects on the side, and perhaps start collecting things for a cap pulser setup and constructing bit by bit. The best work I've done so far, is the work I have forced myself to be patient with.

Thanx for the advice

welcome. I would recommend replicating a ssg circuit and studying its charging capabilities on some new batteries to get some experience. If you get a feel for the basics then you will have a better understanding of the more advanced setups and are less likely to make mistakes. If unlike me, you're an electrical genius then dive right in! I have already learnt so much from the ssg circuit, and it is proving to be a stable platform from which to advance from.

Good luck!

Thanx for the advice Ren, definatly not an electrical genius, I will keep charging, and documenting. I know their is more to learn then what is obvious, Just get anxious sometimes. Need to walk befor I run though.

so this 2V over battery-voltage, is measured with dvm straight on the battery poles during charging?

[ren]

It seems to me that there are two ways to cap dump into the battery. On one side there is a high voltage(high potential) but low current hence a 500-600v cap @ 3.3 uf or such. Then I have seen other setups, like Johns in EFTV2 and Aarons video which have a minimum voltage (usually 2 or three volts over source) but a large current capacity, 100,000 uf plus, maybe even Farads. Id be interested to see if anyone has experimented with both as I am hesitant to spend big bucks on large capacitors if a small one but larger potential will achieve the same result.

2 volts over battery voltage

2V over the battery is just what John told me to start with and that was 6-7 years ago. It is still a good recommendation I believe especially if you're using high capacitance discharges. I was doing 6 caps at 33,000 uf's each.

[terence123]

Hi All. I'm running a 555 on my circuit. On my scope I see the signal over the cap rise to 120V (4.7 micro-farad). The voltage over the battery (4Ah) during charge rises to 16V.

question: when you people report about the voltage over the cap, do you use an oscilloscope or DVM (or analog meter)? And if DVM, (digital volt meter), is it true rms?

I'm confused now, because Aaron saying that it is good just to charge 2V over the battery voltage...

Finally Im in.

Been trying to get in for weeks to post but had some strange problem that also strangly corrected itself. very strange! anyways I have been reading many of the discussions regarding the bedini motors here and thanks to all of you especially you aron for the simplified SG schematic I have succesfully replicated my first SG single coil. Well I havent yet tuned my SG but was thinking of using the cap circuit which was given in the free energy book by John. Or maybe I need to master my first creation before moving on.n What do you think?

[Aaron]

caps and high voltage

Hi Mario,

These caps seem pretty hardy and I haven't had any perceivable problems with them. John has used caps around the same voltages I think and with quite a bit higher capacitance.

Discharge info

Hi Aaron,

thanks for the info. I was wondering, you said you used these hi capacitance caps rated for 60 V, but even if you discharge them at say 16V they still get hit by a few hundred volts from the coil. Isn't this bad for them? Does John do the same?

best regards,

Mario
