Hmmm, i noticed that some of my typing letters are getting auto reduction
nor some sort of percentage bracket in between... No idea why


Any recommendation to avoid such?

Pin 14 is the internal 5V regulator output, so all those 4 pins should have a solid +5V!!
I agree.
Anything below 4.95V on this pin is a sure sign of trouble ...a current overloading or a bad chip, most likely.
4.6V is unacceptable.

  "In my and your TL494 setup, pins 2 and 13 and 14 and 15 are solidly connected together.
Pin 14 is the internal 5V regulator output, so all those 4 pins should have a solid +5V!!

So i don't understand you are able to read "10v down to 0V" on pin 2, it should have a solid +5V"
   end quote from Itsu.

   Itsu: Yes, that is exactly the problem, I believe.  I'll look into it... as it can vary the voltage on that #2 pin from 10v down to 0v as it drains the 4.7uf cap. There lies the error.

Hmmm... on my board, which works... pins 2, 3, and 15 are connected together, and to nothing else. 14 and 13 are connected together and to the non-ground end of the duty cycle adjust pot.

TK,

then you probably use the by verpies presented diagram like here:

http://overunity.com/12736/kapanadze-cousin-dally-free-energy/msg502495/#msg502495


Nick followed the Stalker / Pinoy_tech presented diagram like here:

http://overunity.com/12736/kapanadze-cousin-dally-free-energy/msg507286/#msg507286

Different wiring, same results

  Actually, is was the Ruslan (Oleg), Stalker, PinoyTech designs combination.  I adopted some of the their ideas.
  I took a little from each one of them for my version of the TL494/Uc4420 yoke Kacher/grenade circuit.
  Maybe it's not good to mix and match...?  We'll see.

  I found late last night that my Pin 2 was not directly nor "solidly" connected to the rest of the other 3 pins, #13,14, and 15 pins. Pin #2 is just connected to the 4.7uf cap positive side, but not to the rest of the group of the 3 other pins.  I'll fix that later today.
 Hopefully, that's the problem.



      Well, that WAS the problem. I connected the #2 pin back up to the rest of the three pins of that group, and I now have good clean signals at the fets gates throughout the entire duty cycle and frequency range. Thanks for the help with that, guys.
 But the MOSFETs are still getting too hot, like as if there is a short somewhere.  I'll be looking into that later tonight.

   So, one problem solved, but one more to go.
   And just now my PC won't start. Can't win for losing.

Warning This schematic does not need P2 and C2 and connect pin 1 and 16 of the 494 0 Volts the warning is because the 2 opamps control the same logic you can't have two drivers controlling the same logic IT LOCKS UP !  sorry, Verpies. ;) no offense intended ;)

Nick,

great, now take it to the next step.

(re)connect the MOSFETs to the 10K resistors or automotive bulbs as suggested earlier and scope the gate / drain signals for each MOSFET one by one.
They should show some fairly nice square wave like signals without the MOSFETs getting hot.
Run it through the frequency and duty cycle range to get a feeling of what the different setting do to the MOSFETs signals.

None taken, but no warning is necessary because when pins 1&16 as well as pins 2&15 are connected together, then the outputs of these two error op-amps are identical and there is no conflict.  Also, the OR-ing provided by internal diodes prevents any conflicts.
The TI Datasheet clearly states:
Quote from: TL494 Datasheet Section 9.3.6
Both amplifiers behave characteristically of a single-ended singlesupply amplifier, in that each output is active high only...
With both outputs ORed together at the inverting input node of the PWM comparator, the amplifier demanding the minimum pulse out, dominates.

If you want to, you can disconnect/disable one error op-amp by disconnecting pins 15&16 in my diagram and connecting pin 15 to pin 14 as well as connecting pin 16 to ground.

hi pinoy-tech, thanks for sharing the pcb layout. just wondering if you have the gerber file
 for this pcb  acr 576 so that i can get the Chinese to replicate it please .

Hi Seashells  silly question but why would you want to make a copy of that inverter for ??? wouldn't it be just as easy to plug a 240v bulb into the mains ?? his supply is coming of that computer plug I presume is 240 volts top left of middle of screen befog the 240 to 12v TL494 supply TX.

  He had uploaded some PDF files previously before he went on vacation.  Look for them around March 20 or 21st. 
  Or he may be persuaded to post them again. They are based on Ruslan's or rather Oleg's earlier TL494/UC4420 driver board.  Which is what Stalker has also simplified and is using a version of, presently. Same as I am, as well.

  Here's another short video showing the TL494 circuit and the TC4420 fet drivers in action. Signal problems fixed.
  Thanks to all for your help.

   I'm still working to solve yet another issue with the fets, and I'll know more about that shortly.  I hope.

Nick, 

thanks for the video, signals looking good.

I think your scope is set at 0.2ms/div, so at max frequency setting of your pot, it shows 9 pulses across the 10 divisions, making it (2ms/9) 0.22ms / pulse = 4.5KHz.
Thats kind of low as you probably would need something like 17Khz lateron.

What is your C4 capacitor at pin 5?    Is it 1nF?   Seems to me its much more.

Anyway,  now with the yoke disconnected and the 10K resistors in place, scope the gate and drain signals of each MOSFET, they should be stable now too.


As i have the lossless clamp design primaries on my yoke i can not check if your primaries are wound OK, but from memory they are ok (all turns the same direction).
Perhaps others can confirm this.
