Pull the chip, install a socket, try to find some genuine Texas Instruments TL494 chips to experiment with.

  I'll be done with the snubbers and the rest of the circuit tomorrow. 
  I got the new zeners, resistors,and diodes to install so I can finish the push pull snubbers.
  No pulling ICs, at least not yet...

   Just got my snubber parts order, so I'll install them soon. Any way, this is what it looks like, so far.

hi,

Please don't forget the MOV's which should be rated just below the fast response protection diode(Assume 600volts) used to protect the source drain of mosfet(~600volts...650volts).

Around 470volts rated for MOV.

Without Mov the external "protection diode" will likely be destroyed upon turning on Kacher at the certain frequency but good news is expensive mosfet won't be damaged.

   What is a MOV?   
   I am now following the Stalker diagram that I posted previously, for the snubbers. But I'll be using the MUR1560  instead of the MUR460. Other than that, the rest of the snubbed components are the same.

hi,

MOV is Metal-oxide varistor.

Why use a MOV it's an energy waster and what you drain (waste) overheats the system and wastes your free energy (assuming you ever get any with this concoction) ;)  just use two fast diodes from the collectors a good cap and a bleed resistor back into the system somewhere like the EHT driver supply possibly.

There is also another way of using push-pull energy init's own drive by winding the drive transformer in a more efficient way.

Every dissipative snubber is an energy waster.
It snubs electric energy by converting it to heat.

just use two fast diode...
Diodes in snubbers waste energy, too.
That waste is proportional to their forward voltage drop, so Synchronous rectifiers waste the least energy, Schottky diodes waste more, Silicon diodes - even more, Silicon Carbide diodes - much more, and Zener diodes - the most.
...and MOVs get used up.

Yes, winding the transformer more efficiently minimizes its leakage inductance and the energy that snubbers must dissipate.
It is the energy stored in that leakage inductance that the snubbers must deal with.

Alternatively, the unwanted energy can be recycled back into the power supply by an auxiliary winding....without dissipating it as heat.

hi,

There is specfic reason why Akula used MOV,snubber and even zeners to protect his IGBT's.

I have explained to Nickz MOV is needed to protect the diode.

MOV for my case was not implemented at first since i am using 1.2KV SIC Mosfet with 2x external 1000volts diode UF5408 for each mosfet in snubber section.
But later on i discovered components are getting damaged because of kacher.
So implementing a 820volts  ZOV(Zinc oxide varistor) for my case solved my problem for good.MOV would do as well.
I did learn it the hard way.

Nothing much to discuss since i have shown the snubber circuit in PWM circuit as attachment few weeks back.

But for my other circuit none PWM or PLL variant i am sticking with IGBT used by Akula and had no problems from the start.
Less heat generated because IGBT's are properly driven at the right voltage at around 17.xxvolts
.

-----------------------------------------------------------------------------------------------------------

For nearly 5 years members are still getting stuck in basic PWM circuits.Do think about it.

   Verpies:
   I believe that my TL board is working as Stalker has his operating, and possibly similar to how apecore's T494L set up works, also.  Even though it may not be working as you would like to see it doing. It does produce the same or similar scope shots, as what Stalkers circuit produces, as can be seen on his last very comprehensive and well explained video.
   
   I may make another TL494 board, (without the voltage regulators and filters), and just test it on a 12v battery. That way I don't have to get the first board all messed up with more changes.
   The new board can be made exclusively for testing your "proper" connection method. As I have 4 more TL494 chips, as well as most other needed components.
  However, as I explained previously the reason that your suggestions did not work for me, was due to the connection to pin #3.
 
   As you can see on Stalker's set up, his toggle switch connected (when closed) between the #3 pins, and the three 13,14, and 15 pins will kill the output from the pin #9 and #10. That is exactly what it was doing on my set up, although only one of the two outputs was not working. And that was why I went back to the Stalker connection method. But, without the #3 pin connected up to anything, and just left open, with no toggle switch, as it's not needed, at all. 
   On Pinoy's schematic, the #3 pin is left open, as well as on the TopRuslan schematic. There must be a reason that they are doing it this way.
   
    In any case, I'm not afraid of getting "bitten", and expect to continue testing the circuit, until it WORKS, as expected.
    Thanks for your help. I do appreciated it.

    PS. Although I have been busy with other things, I expect to finish with the snubbers, and will be able to test the workings of the circuit connected to the rest of the device.  I will show in videos, step by step what I've done, and the results of those tests, for myself, and for anyone that may be interested.
                                                                                                                                                                                                               NickZ

Magpower Hi, that's an interesting comment, I did look back at your circuit but am a little confused on how you drive the IGBT's at 17 volts  I was wondering if you might have ment 15 volts via 7815 perhaps and seeing other circuit with IGBT's is a new one on me so to spoeak although I have used them in a couple of driver circuits, I have experimented with myself, regarding the Katcher what type of device are you using there, as Drain Sauce resistance is really important to keep to a minimum there if EHT quality is important ?

Regards AG

Ok, just a quick question about mixing AC signals of LF and HF.

In the configuration below, how do I tune Tesla coil frequency to get maximum power in (third) output coil?? to take energy from 60 HZ AC source.

Try tuning the output coil itself, by putting a capacitor in parallel with the coil and/or varying the number of turns in the coil. You could also try installing a ferrite core that can be adjusted in and out to vary the inductance of the coil.

Nick,

Its important to replicate the circuit as accurately as possible, just in case Stalker has achieved something special. However, its quite likely that you will do some TL494 config changes in the future, as suggested by Verpies, so order up a few IC sockets ready for the changes.
