Akula0083 Light No3 - Dual TL494
« on: May 08, 2014, 05:34:00 PM »
Hi All,

I have opened this thread to discuss the Akula light No3 with dual TL494.

I have drawn a circuit based on what i saw in this movie from Wesley aka Stivep1
http://youtu.be/1BNgo09N0yM

I still need to add the values of the components, but if you like you can help out to.

Please dont add any other circuits from Akula in this thread as it might confuse things more, cause there are somany circuits out there that do not really match up, and i have made this as close as possible as to the origenal circuit in the movie.

Here is the youtube version of the circuit drawing that i made
http://youtu.be/7yJytHhudX8

I will add info on the coil later, but the coil is not hard to make, just a flyback ferrite with 3 coils, 7 turns, 12 turns, and 19 turns ( info will be added later )

For the component values we can compare other common TL494 circuits and see what we need.

If you have values that are for sure then you can add them to the drawing , so we all can fill in the blanks

Thnx!

Greets JB

Thanks John

You will notice the schematic I referenced came from someone who reverse engineered the board at the site you signed up for. The controls sequence position on your drawing agree exactly with the legend on the right of the schematic if flipped vertically.

I am working to fill in some of the component values on the right of your drawing, also am checking the layout.

Thnx Vortex,

I will try to make the left side of the circuit first, with same values used from that circuit you showed.

Once both TL494 work i will try to fix the mosfet drivers.  If i dont have those parts i would have to order them, or i will use the MC34151 mosfet driver that i also in my ACMMJB circuit.

I will also compare the circuit with common tl494 circuits by using google images.

Once all is working correctly, thats when the search for ferro resonance starts

Akula also mentioned his principles are based on Trangenerator Andrei Melnichenko magnetic field

Just for comparisment, i added the pic you showed, so we atleast have some start values.

Made the first signal gen IC1

The components i used for that are

R3: 4.7k
R4: 2.2k
R5: 82 ohm
C4: 222 aka 22nf
R6: 150 ohm
VR1: 10k aka 103 - 1 turn pot
VR2: 20k aka 203 - multi turn pot

frequency data
Min Freq: 31.2kHz
Min DC: 6.3%
Max DC: 87.5%
Min PW: 2 uS
Max PW: 28 uS

Max Freq: 660kHz
Min DC: 4.1%
Max DC: 76.9%
Min PW: 62.5 nS
Max PW: 1.17 uS

Input power used 6.86v @ 0.05mA

The scope was connected at pin 9, cause i did not really get a good signal at the end of the 1n4148

I have completed the circuit, and is ready to be tested.

I will still test different mosfet drivers.

The pot in the center acts like a voltage limiter from 5v and up, when i go above 5v the 2e tl494 goes of, but if i turn the center pot then the 2tl494 goes on again but goes off by 6v etc etc.

The duty cycle of the 2e tl494 doesnt go higher then 37% and max frequency is about 336kHz but i will have to play with that some more.

The 1e tl494 acts like the oscilator, and the 2e as a solid state tesla or inverter circuit.

For mosfet driver i used the bc557b (tr1) transistor and the mosfet for now the irf3205

I have noticed that when 2 harmonics from both tl494 come close to each other they automaticly attract and melt together and turn into 1 big harmonic, its like a lock on when they come close together.

Sofare no noises from the core, and the led stays longer on when closing the switch but that is because the cap C1 helps out.

But the circuit is ready to be tested to the fullest, i have added resistor R9 ( 4.7k ) from vcc of the 2e tl494 and going to ground, and R8 ( 82 ) ohm comming from pin 16 going to ground.

Instead of the SF56 i used the HFA08TB60 cause i use that in my ACMMJB to capture extra energy going to my 2e ouput of my ACMMJB

Once all is working as i want it, i will solder everything to a pcb

I will also update the circuit drawing,


Thats it for now! :)

@JB,

Nice work! Keep us up to date on this I would be very interested!

All the Best

  Chris

P.S: My circuit draws way too much current to be powered, I should say started from a 9 Volt Battery that's why I started to look at the series resonant ideas that are incorporated.

How I understand, can be modulation feroresonance, then posible put to transistor packs of pulses, duration betwen packs is standart transformatio and duration and frenquency of pulse is feroresonance frenquency.

Akula say, that burn many ferites, then long hold on feroresonance its. Burn means, probarly, that ferite lose important features. And say, that must be sinchronisation of two generators by first fronts, end fronts syncronise comparator. 50 ns if be diference, here is to much.

Akula advice make sinchronisation with triger, because triger lets you make synchronisation in range 40-50 nanoseconds. Without triger wery dificult sincronisate, if you try sinchronisate with inside comarators, that make be almost not possible, you stop in range 1 milisecond. Any triger lets you make sinchronisation in range 50 nanoseconds, then you not destroy feroresonance in that small divices.

Hello All,
I hope this helps.

It's a big help, thanks.

The area I question (lower right just above the input capacitor) is right  after  and below the switch. I think that the power to the two coils (dots) comes from the land area right after the switch, and it is shown after the diode on Johns sketch of the layout.

This would conform to the revised schematic.

Finally getting some high voltage :)

when rectifieng i get 7,8v when bulb is connected without bulb OL on meter.
when hooking up directly to the coil voltage is 22.7v

https://www.youtube.com/watch?v=7tOtGrWX9IU

i will do some more tests.  only thing is that my scope shot looks like crap, must be some disturbance going back to the mosfet, what can i do about that?
