It seems strange to me that you can turn up the duty cycle on that pin 10 signal to about 98%.
Yes, such variation should be possible only when pin 13 is grounded.

For anyone interested, here is the TL494 schematic with separate dead time and duty cycle adjustments:

Dear Verpies.

That's a great start! How about going one step further and add the driver section? One suitable for both
MOSFET or IGBT.

If such a diagram could be prototyped I might even jump into the " affray " again, knowing that at least one part of it would work correctly!!   ;)

Cheers Graham.

Here the link to Nick's latest video showing the pin 10 output only:
https://www.youtube.com/watch?v=irIKzaCY1Q8

It seems strange to me that you can turn up the duty cycle on that pin 10 signal to about 98%.

Itsu


   That video is showing the signal from pin #9 on the TL494.  Pin #10 is the one that is showing no output, still.
   I do have several more of the TL494 IC. But, I hope that I don't have to pull it out of the board, just yet.
I'll continue to look for the problem.
   
   Please watch Stalker's last video showing the workings of his newest TL494 circuit.  Peaks are in the
middle, as I had shown previously. Check his diagram, also, and let me know what you think.
 The thing is, that he does not show what it can do at the output towards providing for a self runner.

  I have checked and touched up all of the possible connections to the #10 TL pin.  And still no output from that channel. I see no other solution other than to pull the faililed or shorted TL494.  A job for Super Man...
   Wish me luck.


  The other output at pin #9 seems to be working OK, although it's proper function has still not been confirmed by Verpies, nor anyone else.

Good day NickZ

A quick recap:

If pin#13 (output mode selector) is *grounded* then push-pull mode is inhibited;  if you are able to reach 98% d/c on pin#9, then something is NOT correct.  For a push-pull topology, the maximum permitted is 48-49% d/c  per Channel (output 9 & 10) as the *DeadTime* will consume the remaining d/c, ie; 2-4%.

I would verify the function of pin#13; 
Pin#13 >> Ground = Single Ended operation;  d/c = 98% max / channel.
Pin#13 >> Vref     = Push-Pull operation;       d/c = 48% max / channel.

I hope this helps.

take care, peace

Good day Grumage

Check Verpies Lossless Clamp / driver circuit.
That can be used *as is* with the previously posted TL494 circuit.
You can set the Lossless Clamp circuit up to switch in/out the regenerative clamping portion for your experiments.

take care, peace

Yes but why not get the device working and then refine it, after all something else needs attention as we only have what they want us to know, not what we need so badly to know.

Good luck!  ( I learned some time ago always to use sockets for chips in my experimental circuits when possible....    :-[    )

   The TL 494 has the #13 and #14 pins soldered together,  and going to the #1 pin of the duty cycle pot. No ground.

I may have to rewire it again possibly useing Stalkers TL494  circuit, which is different than Verpies posted diagram.
He has the 13, 14, as well as the 15 pins joined together. Among other changes.
  Many ways to skin a cat, just wished that one way works.

  I'll rewire as I had it previously, just see if I can get #10 pin to show an output,  again, before I try to pull out that IC.

   Thanks or the tip TK.   However I'm not close to where I can get solder wick,  nor a solder sucker.  May have to just cut it out,  from the top side, and then remove the cut off legs.   What fun!!!
  But, it maybe that the TL chip is still OK, I hope.

If you do that, then pin 16 must be grounded.
That change does not alter the operation of the circuit I posted here.

Just like Lost-Bro wrote, but without the 74ABT04 inverter.

Wesley,

Is this the 'surprise' part 3 video you told us you would be posting?

@Wesley: I don't understand the principle of electrostatic pump conversion - it's still too ad hoced. Will you explain it in some future videos?
