Capacitive Battery Charger & Capacitive Transformer

Danger!

Circuit too dangerous to replicate.

That is a very dangerous circuit and should not be posted on an open forum like this.
People with little knowledge on electronics can kill themselfs with that circuit.
The moment you remove the leads from the battery a voltage of about 150V will appear on that leads.

I wish some people would stop trying to censor me. Open means free. It wouldn't be much of an open forum if I censored this information, now, would it?

But to placate the critics and safety trolls, I'll put up a disclaimer.

That is not a capacitive transformer. It is a reactive voltage divider. The impedance of different capacitors will differ based on their capacitance, and so will offer differing "resistance" to the AC current, meaning you essentially have two resistors one after another, creating...A voltage divider.

This is a true capacitive transformer, and a very good idea.

I was reporting on the booklet. George Wiseman, the author, calls it a capacitive transformer.

Yes I see that, no fault on your end, but it really is just a voltage divider.

Interesting concept—your C-stack.

Correct me if I am wrong, but...

I've looked over the circuit, read the pamphlet, and as long as you follow the instructions, AND USE THE SECOND CAPACITOR, not just run the circuit with a single one...

it appears that what you will have at the batteries, is whatever you designed the circuit to have... and nothing more.

It would appear, the danger level is, whatever you set it to be.

I think that was George's whole point. It's not like he's a dummy. Furthermore, his commercial electrolysers exploit this method so they damn well better be safe and have probably had to go through CSA?

Thanks. Just an observation, not a "known"

Thanks for the link.

Great Post!

Great post and thanks!

A while back, I purchased a booklet from Eagle Research on capacitive battery charging for about $10. They included a booklet on capacitive transformers free of charge with my order.

Essentially, it shows how you can charge a battery using a capacitor instead of a transformer.

I thought it was of interest.

Funny, I did not know this thread existed. I started on some research nearly identical to this, however instead of using multiple plates it was to test the displacement theory of current.

The circuits here are the same as what I've tried. running the neutral lead to the bridge puts the circuit into the mains circuit and as such will always see a load, so that amperage can get dangerous if not careful.

I was more interested in Psi charge fluctuations, Although the amperage I'm getting is low, it's not drawing from the circuit on the capacitor.

I read thru that, thanks

Any idea where this went if anywhere? It's exactly what I've been currently working on. There is some strange things with capacitive transformers, they don't obey conventional electrodynamic theories for one.

Hi madH,

Could you state those strange things you have observed with capacitive transformers? What have you been doing?

Thanks!

going to dig up the thread I started on this, check there for updates

Change volage/ capacitance?

Hi
Couple of Qs:
1 My mains V is 250, can I build one or must I step down to 120/150- I have capacitors rated 450V AC and bridge rectifier to 1KV.?
2 My caps are only 11 MFD each - can I parallel some to increase the charging current?
Thanks!
