Bedini Solid State Oscillators

[blackchisel97]

I re-make SSG Bedini motor and make this scheme

I don't why - but it's work. I have 8 cuircit coil and 5 c.coil.
The 3055 transistors.

The nois from the coil near 440-450 Herz ( a note of 1 octave)...may be this frequency is real. Now i can't to measure this.

But I have a questions. Why it work?

I have 100 Ohm per transistors.

Thye diameter of the wounds near 0.51-0.56 mm. Resistance near 10 Ohm. 700 turns. Air core. Whean I put the welding roes the freqiency coes down and it's stoped.

Why thebattery charge quickly (60 A/ Ah) but 40W buld discharge very fast. I was make near 10-15 cicles. And What the high Vo;tage lever for charge. It's hear a little noise rom batery near 13.6 V, it's HHO...It's normally?

It sounds like your circuit is self oscillating due to the base resistance being too high. When you inserted core self oscillation stopped. You'll notice voltage climbing quickly but it will be mainly surface charge. There is a gassing and HHO present during charging. Make sure you have a good ventilation and be careful with sparks.

Thank you V

Now I am use 50-100 Ohm base resistor and bulb/lamp with near 200 Ohm resistance.This lamp 14V 50 ma is like indikator and resistor.


Yes, it's true, when I use the core - the oscilations is stoped.
The air core is work and charge.

But tell me plaese why 40W lamp/bulb 12V is discarge the 60A h lead acid auto batery for 1 hour?

I make charge to 13.86 Volts. And discharge to 12.45.

May be 10 cicles is not enough? As far as I am understand , this kind battery may discharge more longer?

How many cikles I need for charge. I have a new battery.
Or I am make something wrong?

The first charge was be fast and the discharge is faster.

What I must to do?

My 20 transistors 100 (near 100 ma per one tranistor) charge for (1-2 hour) this battery. yes? it's- very quckly. but why 3.5 Amp of the lamp make fast discharge?

What is the mainly surface charge?

[blackchisel97]

What is the mainly surface charge?

Battery appear to be charged according to the voltmeter but there is no actual power behind, mostly potential showing.

I charge my batteries until they reach at least 14.5V or more. After that I start cycling them by discharge/charge processes.

60AH battery should hold charge longer than that. It may be still sulfated and doesn't have sufficient capacity. Glass density meter for electrolyte makes good indicator of such.

Try to keep charging longer until battery reaches at least 14.5V. Let it rest and make a note of its resting voltage. Discharge and make a note of time frame. Let it rest and charge again. You can also connect one clip of voltmeter to one of the terminals and use a piece of bare wire attached to the second clip. Now you can probe each cell starting from the terminal to determine the weak one. There are 6 cells and each should read above 2V.

[nafanja]

Thank you V

But the battery is new.
I was bue it at auto-shop. It's strater lead acid batery, packaged.
What is the sulfatation process may be?
The Voltage was be 12.6. The discharge has made by 40W lamp.

The week or more I don't make charge to 14.5 Volt.
Charge system in the auto is 14.5 Volt. as i am uderstands - the charge must be to 14.5 Volt.

But the first discharges was show me the very quck discharge.

Now I have 19 transistors and the Voltage stay charge fast.
but today morning I was find that this system to chare the batery very-very fast. Super fast.
The DC clamp-meter chow me total curent near 4.5 Amps.
But the bulb discharge the battery to 12.5 Volt very fast too. The battery try to stop the quck/fast discharge at the 12.5 Volt. May be the starter lead acid battery start slow discharge from 12.5 Volt or may be the batery was remember my charge to 13.00 Voltage?

What is the low Voltage may be used? You say about 12.35 Voltage, but starter battery when the car is start - stater moove the Voltage from 12.85 to 10.8. After that the car generator make 14.5 Volt.

I don't know what to do.

I have a good condition GEL lead acid 60 A h battery.
It's my second battery.This battery was chare by the standart (from the complecte) charger.
But situation is the same.
I may make the quick charge but the Voltage go down and stopped to Violtage which maked by standart charger:
I charge the batery by standart charger to 13.3 Volt. After that I discharge to 12.45-12.55 Volt by 40W bulb.
After, I connect the self oscillator and the charge is very fast. But when I use 40W 12 V lamp - the discharge is stay 12.55 very quckly. And stoped at this point ( 12.55V).

May be I make something wrong when I make formimg/condition proccess?

@ nafanja

HI! I don't see what is your problem, your battery seems to be good, you just don't know how to discharge it . If you want to see the full capacity of the battery try to discharge it to 10,5v (under load), then let it rest for one hour and then charge it up to 14,5v or 15.10v and let it rest for 12 hours and see the voltage - it should be around 13v.

You give me the answer)))

Dear V

YouTube - ‪6 FILAR SOLID STATE SG‬‏

As I am understand - it's your video.

What is the resistor at the trigger(first coil)?
I would like to replikate your schame.

How many wounds do you have at your coil?

As I see - the charge of your large batery a impressivly fast.

[shubhamforme]

one of the best solid state chargers..

hi ,
i am using this type of charger to charge my batteries and surely charges them well,
i have also recovered a 9v nimh battery with this set up...

i would really like to have everyone comment on the design and give their views..

i've beemn facing a problem and that is that either to use a single big toroid to make all the coils winding in one toroid or to do single winding of all 4 coils saperately on different small toroids...
I had tried both the setups and performs totally different in both the configurations...as i dont have an oscilloscope so i am not sure which configuration is the most efficient one...
kindly help me out
thanks
shubham

[sucahyo]

i would really like to have everyone comment on the design and give their views..

I think you need at least 100 ohm resistance between pin 3 output to each individual MOSFET. try 1K. but there are other design more correct for MOSFET. maybe need 100K resistor or something between the pin 3 output to negative and positive.

The questions




Dear V and everybody)))

I make the scheme which on the video.

I have a many questions:

1.Iam using the 2SC3281 Toshiba transistors. It's what I may find now. 15 Amp and 200V.
How I must tune this scheme for this transistors? May I use those resistors 10k 20k 220 Ohm?

2.What it's need for tune this SS with 7 transistors or how to tune the R1? I use 360 Ohm and I have impression that the scheme charge better with the resistance. But this resistors is warm. I some 2 or 1 W resistors. The scheme is have 1.8 Amp when I measure by DC clamp-meter.
3.As I am understand, you use 1 mm diameter ware for coils. But at the video it's looks like 0.8 mm. My 0.56 mm diameter ware is warm, near 40-50 C. As I am understand, the warm or hot ware is mean that the ware must have more diameter? Warm – it's mean the I have a loos? May this give a low charge? I look the video and the time for charge very impressively. My charger can't make fast like at the video. I would like to understand what it's need for get those speed of charge? My transistors is cold and they don't built to the aluminum panel. It's only the ware is warm.
I must have 1 mm ware?
The ratio must be 1- 1- 1- 1... or 1-2-2-2...? I see the 1-2 or 1- 1+1 Tesla coils variant at tis topic.
I show you the right direction of ware at the scheme? I was turn/wounding the coil with 8 wares, all wares has wounded/turned together. The first (master) coil is connected by low pin to “+” and the high side to BASE. I right?
How many turns/wounding the coil must have.? Aron's scheme (with 3055 transistors) the coils have 2000 turns, may be I need more turns?
At this time I am charging the 60 A h battery. But I have impression that it's will be the day. But at this video is a large industrial battery ad how many Amp/h they may be. It's looks like more than 100-150 A/h.

The diodes at the video looks like big diodes. Why it's need 1n4007? May be the Ultra fast diodes is better? I have 100V 15 A ultra fast diodes. May I use at this scheme? I wish to charge 60-100 A h batteries.

Does I need transistor cooling when I will try to make 24 Volts of power bock?

Does I need transistor cooling when I will try to make 24 Volts of power bock?

First of all, You have a mistake on your schematic. All transistors are NPN not PNP as VT3 as you have.
10 and 20k resistors are fine. 220 Ohm in each base should be fine too but your schematic has an error; each transistor should have its own base resistor. All of them are connected to the common adjustable rheostat or experimentally chosen resistor with or without the bulb in series. This resistor (rated at 10W minimum for such setup) is connected to the trigger coil wire. Other trigger wire can be connected to the negative rail (input neg.) or in inverted trigger fashion - to the positive rail (input pos.) I have 1:1 ratio in all my coils except wheel Simplified SG.
I used AWG#18 wire. All windings are the same length, 100' and twisted together. I power mine from 20V DC and coil is warm to touch. Transistors may be the same temp. At 12V input everything stays cold.
2000 turns are not needed for this setup. I don't count turns, just stretch the wire, cut into desired length and twist with cordless drill.
Of course you can use thinner wire if you have such at the moment. You may compensate thinner wire with more power windings. It should charge the same with 5 x #18 or 8 x #21.
You need 1000V rated diodes. Fast ones are ok as long as they're rated at such V. 100V diode will not survive.
If you decide to apply higher input V you'll also need to readjust base resistors for higher values and adjust common resistor accordingly. Also check the temperature to see if any cooling/ heatsink may be needed. Small PC processor fan will do the job if necessary. I have one to keep everything cool.
With highest setting in my 6 filar SS the current draw is about 4A and 0.8A on the lowest.

I hope this answered most of important questions you had.

[nafanja]

Thank you V

I try to copy your schame at this video.

YouTube - ‪6 FILAR SOLID STATE SG‬‏

Now I repaint the scheme and please look this.


I try to use 7 traiansistor for make the replacation of YOUR scheme.

Tell me plaese, how to tune the resistor R1?
And how to find the resistors at the base when I will have 24 Volts at the input (Power Block)

I have this scheme (like on the video), but my replication is not charge fast like at your video. Very long time.
I try to understand what I make wrong. Hopw on your help.

Tell me plaese, what is the resistor do you use at R1 place? I am aboutr your video.
YouTube - ‪6 filar solid state 2.AVI‬‏

The transistors is not with the heatsink and coolimg. They cold. But the coil is hot or warm. may be something wring?

Do you have the secrets for fast charger?

Do I need the Collector Emiter diod at the 12 and 24 Volt input power?

I have a question about the L1 or Triger coil. Do I show the coil pins write. The side with pin must connect to "+" of power and highest side to the base rsistor?

[blackchisel97]

Yes, this is correct.
I also have bridge rectifier connected to the output and pos/neg from the bridge going to the battery. You can charge off the diodes too, as per diagram.
Collector-emitter diodes are not necessary.
You can try with 200 -300 Ohm base resistors and 100 -150 Ohm common one or you can use 50 Ohm and 12V5W bulb in series. Bulb should barely glow. When gets bright than you have too much current going into the bases. I use MJL21194 and adjust resistors to have about 200 - 250mA going to the base of each one.
Don't worry about pins. If it doesn't work than reverse trigger wires.
My battery has been formatted with radiant chargers and they'll charge faster then regular ones. They will also climb up to 16 - 20V. New battery will not do that right away.

Tell me plaese again: how to forming the battery 60 A h or more?

When I make many cicles of charge -discharge and I make discharge to 12.35 Volts my lead auto-starter acid battery 60 A h very quick go to 12.35 but charge fast. At the naearest days I was discharge to 11.6 and 11.3. After that the batery stay to charge very slowly. Thay chage good to 12.00- 12.20 Volts and after that stay charge very slowly, but not like on your video.

I was see the recomendations to not discharge the battery to 12.20-12.35 Volts. but when the car is starting - the charge from 12.85 Volts go fast to 10.8 Volts intill the car is run and the generator make 14.4-14.5 Volts of charge.

As far as I am understand the starter car battery made for strong starter currents. The starter at the car near 250 Amp. I was see the diagrames and test of starter car battery and Optima and other may run the 250 Amps near 20 seconds. I would like understand how people use lead or lithium baery in electric car? The lithium battery may work in 0.3C.
I was see the test of one lead acid batery which may give 100% curent to the lioad, and people was charge this battery by big curent near 1.5-2 hour.

I try understand what kind of battery I may use for electric car and the home.
I know people who need 7 kW energy. And I try uderstand which kind of btery to use. How forming the battery and many other.

As I am understand the Solid State JB Charger not have the rotor. more smaller and may be charge a little faster. isn't it?

I try to undrestand, if it's will be the China lithium batterty 90 A h with 0.3C variant that mean 3 hour discharge by 30 Amps the 240V sanwich and 30 Amps = 7200 W per hour. Does cmake SS Charger the charge in 3 hour?

For example I have two sandwich. 240V. One bankes (3 houres) is discharge and second bankes/sandwich is on charge and thiees bankes is replased in time.

As far as I understand, the MJL21194 is may work up to 250 Volts. I just find 15 Amps and 200Volt 150W transistor Toshiba. as I am understand this transistors have nearest parameters and I must built it to heatsink for cooling.
My transistors is cold at the 12V , but 25 Volt make them hot.

As I am understand, I must to have thinner ware. My ware 0.56 mm is very warm and very hot at 25 V0lts. The rectifier diodes in input or power block without the heatsink is make the smoke. I need to cooling them too?

What is a better for fast charge - the higher Voltage or low Voltage and built more transistors?

Dear V: how many time do you forming your industrial battery. What is the discharge level do you make? It's battery near 100 A h? How many cicles did you make?

[nafanja]

The triger coil direction

Dear V

Tell me please how right to connect the trigger coil?

The down out of cil at the scheme or point side (Collector side of power coils) must connect to the "+" of input/power. The highest side or opposite of point side ( "+" power side of power coils) goes/connected to base resistor, I am right?

May my thikness of the ware ( 0.56 mm) give the losse of charge?

Today evening

At the nearest time I found two lamps/bulbs 3W 12 Volt. I am connected for get 6W that nearest power or resistance of 5W 12 V lamp. The lamps stay make a little light. But my clamp meter (when I clampimh aroun ware) is show me 6 Amps. It's mean that each from 7 transistors get near 0.8 Anps. I don't know may be my DC clamp-meter is not correct?
But the Voltage at the charging battery stay less and the charge is stoped.

I add 250 Ohms resistors. Clamp-meter is show me 1.6 Amps. The charging is start.
It's mean that my transistor have more amplifiring base current?
The light of the bulbs is off.
