RE-EMF Charger

[Blargus]

Hi,

Was wondering if anyone knew how to look at the spikes with oscilloscope...I'm stumped at the moment . Some things I noticed from my breadboard version--it doesn't seem to hum with Bedini bifilar 18 AWG coil and 2n3055, but it seems to work pretty fast so far . I also have possibly transistor heat issues, but might be ok at 1k ohms potentiometer setting so shot in the dark will maybe try 2sc3552 instead or maybe heatsink. I think not at all close to 400 degree F max of 2n3055.

Looking forward to testing this, it's so simple! Simple is best! Thanks Rene!

Hi Blargus!
Do you try to connect the scope probe on the negative charging battery and the colector of the transistor...?
It would be great to see a photo of your scope mesure!
Ciao!

Hi Blargus, I've been using a 2SC2555 lately as it was the only one that was giving any kick with my setup. 2N3055 didn't cut it at all. I just put my center scope lead on the positive going to the battery. I don't even connect the ground but that is probably not needed in my setup since both o-scope and power supply are on same outlet. I've also found the spikes vary greatly depending on the input power. I'm using a 0-30V DC supply. At around 10-13 volts the spikes are big and narrow. At higher voltages they get lower and wider and more current is being drawn from the P.S.

Hi Wistiti and ewizard,

Thanks! I tried the probe on collector ground on neg of battery and some others. I will try to post a photo of the waveform when I get it, maybe with different transistor...or power supply! Noticed that as battery approaches full charge, the transistor doesn't get as hot. That's very interesting about the voltage of the power supply changing the waveform and the current draw!

I just found another interesting thing for this circuit. It caused the o-scope pattern to jump about 5 times higher in the spike. It's not only higher but a different pattern that looks to me like it will charge even better and faster. It's still essentially a square wave with a spike on top of the upper left square and more solid looking all the way around. To get this effect I just added an antenna to the base of the transistor. This antenna is only about 20 feet total and goes out my window after the first 5 feet. I think it would probably work even hanging around in a room.

My first construction of an electronic circuit

Good harmony to all of us,

thanks for your work in spreading the free energy,
I am an Italian, I write from Italy, I know little English and my message is created with the Google translator.

I have no experience in electronics and analysis tools having only one meter and an ammeter, and for this I ask you a helping hand in the creation of the charger RE-EMF.


According to the understanding of the circuit, list the following components of the circuit RE-EMF that I have available at the moment:

A) Transistor: 1 (TIP3055) or 1 (TIP31C) or 1 (TIP32C) or 1 (2SC3552);

B) Diodes: 3 (UF5408) or 6 (UF4007);

C) Resistance: 1 (330 ohms);

D) Potentiometer: 1 (1k ohm), 1 (10k ohms), 1 (100k ohms);

E) Coil:
- A coil with two-wire (magnet wire - diameter 0.7 mm.) Consists of a toroid outer diameter of 2.6 cm. (see photo for understanding)
- 1 coil with a wire (magnet wire - diameter 0.7 mm.) Consists of a, a toroid outer diameter of 2.0 cm.
- From a PSU, 1 toroid outer diameter of 27 mm (1.063 inches)
- Enameled wire (diameter of about 0.5 mm. - 24 or 25 AWG) long about 9 mt. (29.52 feet);

F) Batteries available:
- N ° 2 (06V - 5.0 Ah) - 1 (06V - 4.0 Ah)
- N ° 1 (12V - 2.0 Ah) - 1 (12V - 2.1 Ah) - 2 (12V - 2.3 Ah)
- N ° 3 (12V - 7.0 Ah) - 3 (12V - 7.2 Ah)

G) Optional Components:
- 3 capacitors of the type 250V AC
- 8 diodes UF4007

the coil with two separate wires for half, the single-wire coil and the toroid.jpg

In relation to the components described above, what and how can I use them better?

What type of diodes and what type of condenser in the circuit after the release?

What and how to connect the source and output in order to charge more batteries?

If I put a flat coil wire tesla can be better?

In the understanding of my little knowledge in electronics and, in wishing to help in this first embodiment of an electronic circuit,

Good operation constructive evolutionary loving to all of us

Hi! To all!
Ewizard, thank you for your update! i will shurely give it a try! Do you try to put a ground connection someware???

Hey Maurizio, i sugest you to use:
Transistor: test each npn... But 2sc3552 it's a real good one
Diode: uf4007 good!!
Resistor: 330ohm ok!
Pot: 1kohm or 10kohm ok!
Coil: do your best. But it must be bifilard ...

To evreyone, my best solid charge its with higher ohm on the pot... For my test 2k ohm +330 ohm. But take your time .... To full charge a 600a power pack it's take 30h00...

[Blargus]

Was going to ask about the diodes, I am using 1n4007...not as fast as uf4007? Here's what I get with probe ground to neg of battery and tip to collector of transistor (ECG2348). Maybe I have wrong diodes? Or maybe spike is being absorbed by battery like in Bedini SSG?
.

Good Luck animacosmica!

Good harmony to all of us Wistiti,
thanking you for your help,
to understand the response on the power supply wonder:

A) connect the AC 600V output on the verge of the battery charger or AC or DC output of the small circuit (separate in the top right corner as shown in the figure) with 4 diodes and capacitor to the circuit?

B) What are the 4 type diode and capacitor placed in separate small circuit mentioned above and what is its name in electronics (I think a simple inverter)?

C) What type and what is the 600V power supply can be found in the commercial sale?

D) The batteries recharge can be directly connected in series or in parallel to the output shown in the circuit without the aforementioned small separate circuit (4 diodes with capacitor for AC-DC)?

E) To improve the efficiency of the circuit, you can replace the coil wire with a flat coil 2 wire tesla?

The many questions I described above are useful to better understand the electronic components as they are the first electronic circuit.

Thank you for your loving support,
good operation to all of us

No, No ground but since I'm using a plug in the wall power supply the negative from it may be grounded or it could be isolated. Not sure right now but will check later today or tomorrow.

Cost of the circuit... around 2 dollars... Now thats fun !

Very excited about this concept, Rene & all for sharing, will have to dig around in the junk box to see if we have all the needed parts to put this together, will post results as we get them.

Hi Maurizio,

A) It is not 600 Volt but 600 Amper power battery pack what Wistiti mention to charge up during 30 hours, ok?
The 4 diodes with the puffer electrolytic capacitor on the top left corner is an alternative suggestion to operate the circuit from a 12V - 15V AC voltage (taken from a wall plug-in 50 Hz normal mains transformer, small power)

B) The four diode is connected to form a full wave rectifier or a diode bridge (a Graetz rectifier if you like) and with the electrolytic capacitor 1000uF or 2200uF 35V they give a clean DC output to feed the circuit.

C) There is no 600 V power supply as I wrote above.

D) Yes, the batteries can be connected without the 4 diodes and capacitor IF you have at least a DC voltage source of 20 Volt output to feed the charger circuit as shown in the diagram. Such 20 V voltage source can be made from two series 9V batteries (2 x 9=18 V no problem the missing 2 Volt). Or even you may wish to use three 6 V batteries in series. Or you can use any power supply from the mains voltage that is able to give a DC voltage output of 18 to 20 Volt at least with say 500 mA load. Wall plug-in power supply in that range is okay too.

E) Yes, experimenting with coils is always good, in this case I do not think the coil is very critical so what you show as toroidal cores in your previous post is good for a start.

Good harmony to all of us Gyula,
I thank you deeply for your response which gives me more understanding and clarity as I can, at best, realize the circuit RE-EMF.

About the toroid of 3 cm in diameter,
use an enameled wire 9 meters long
The wire fold it in half and then wrap it with a drill so as to form it pulled the wire type beds.
After the wrap in the toroid

We thank you for the help given,
good evolutionary operation loving to all of us

What is the value of capacitor after diode bridge ? Is that a diode bridge or a set of 4 ultra fast diodes ?

[gyula]

Boguslaw:

see answer to question B in my above post.

you can use the usual diode bridge (that include slow speed diodes) for the 50 or 60 Hz down-transformed mains voltage, no need for fast diodes. Just a simple low voltage full wave rectifier with the puffer capacitor.
