35KHZ AC RECTIFIED QUESTIONS

[magnetman12003]

I been experimenting with a plasma globe for quite some time.
I have used a full wave diode bridge to rectify the harvested voltage/current and presently have 2800+ volts after rectification. Better than 35 milliamps. I know this DC voltage is pulsing voltage and my question to all is can I use 10 volts of this pulsing  DC voltage and store it inside a 20 volt rated capacitor? Without the cap blowing up.   Or does the voltage have to be almost pure DC to store it?    I found a slick way to downsize 2800 pulsing volts and come up with 10 pulsing volts and lots of current. I have a huge car audio type 20 volt rated 20 FARAD capacitor I would like to store the energy in.

Any help appreciated.

Yes, Capacitors (both polarized & non-polarized) can be successfully charged
with pulsating DC.  The most important thing is that you don't go over the
Voltage rating of the cap.

No sure if this thread is still alive but here is my 2 cents:


I know that P=V*I


That beeing that your input power is 12W=P,  with  V=12v and I=1amp (lets say) ... an then you use a transfo to change this to   V=1200v using I=0.001amp for the plasma effect...


If you harness you 1200v in your cap or caps, there a good change you will get the same power spread to each one of your caps over time.


This is not free energy ... its transfo effect and distribution effect, like a hose to a yard...you may collect the dropplets and fill the jars,  but your not making anymore water here.


Voila.

that sounds interesting. if plasma creates the potential for more collectable energy at the same time than being limited to the input power.

if that is the case, could some sort of low powered inline overcharge protection circuit monitor levels and switch over to a 2nd then a 3rd etc capacitor until the entire bank is filled, then have some small fan or heating element to take care of the rest?
or even skip the fan and the element, instead using air conditioners tv's or other electrical appliances and charging systems that stay running and drain the capacitors in a cycle?
hmm..

or is it only possible to get the same power rating as the power supply the plasma bulb uses, no matter how many extra power drawing metal conductors are connected to the surface of the globe?
and if that is the limitation, is there a way to recycle any losses of energy that left the globes outer surface without actually physically having anything connected to its surface? (radiant) i guess not. those would be is the term 'inductive'?

somehow i imagine its still limited to the plasma bulbs power supply.
and having mulitple connectors on the surface would only cause the arc inside the bulb to divide up its rated power limit, as smaller arcs only transferred alot less power than any main arcs would create.

after looking up plasma globes:

Hazards

Bringing conductive materials or electronic devices close to a plasma globe may cause the glass to become hot. The high voltage radio frequency energy coupled to them from within the globe may cause a mild electric shock, even through a protective plastic casing. The radio frequency field produced by plasma lamps can interfere with the operation of touchpads used on laptop computers, digital audio players, cell phones, and other similar devices.[1] Some types can radiate sufficient radio frequency interference (RFI) to interfere with cordless telephones and Wi-Fi devices several feet away.

If a tinfoil hat is placed on the globe, capacitive coupling can transfer enough current through the foil to give a small arc burn or light a small lamp connected to earth ground. This is possible because the globe's glass acts as a capacitor dielectric: the inside of the lamp acts as one plate, and any conductive object on the outside acts as the other capacitor plate.[3] This is dangerous to do, can damage the globe, and presents a fire hazard.[1]

haha, a tin foil hat.
