   Verpies, TK, and All:
   Well I finally got my order of new IRFP260N mosfets, but what I actually received were IRFP250P. So, I guess I'll make due with them, instead.
   
   As my TL494 board seems to be working now, I connected up two new fets to it, but find that they still heat up, as they had done previously with the now burnt out fets.
   So, my overheating problem is still with me, and any help or ideas are welcome, in order to solve this issue. 
I only get very low light output at my bulbs, so, there must be something which is not right, and which is causing the burning out of my fets.
   
   I also replaced my TL's board output resistors with new 1k resistors to ground, (instead of the 460ohm), and also the 1k resistors going to the TC4420 drivers, (instead of the stated 1k5 resistors). I had only 10 ohm resistors going to the drivers, previously, and 460ohm to ground.

Are you still using this circuit ?

I had only 10 ohm resistors going to the drivers, previously, and 460ohm to ground.
That would have given you faster rise and fall times.

If the TL494.pin13 has 5V on it and you are taking the outputs from pins 9&10, then it means the TL494 is operating in push-pull mode with active-high pulses out of emitter follower outputs (pins 9&10 are emitters). 
The TC4420 is a non-inverting driver and the IRFP250P is an N-Ch enhancement mode MOSFET so their polarities are matching with active-high pulses.

I am afraid it will be difficult to help you without a scopeshot of drain currents and drain-source voltages.

Nick Hi have you tried disconnecting the yoke 3 to 6  turn winding from the 0.47 uf cap and connecting a car tail light bulb or head light bulb and seeing if the driver stage can light it up mine can light a 50 watt bulb up no problem, if it can you might have a shorted turn somewhere, see if you can break it down till you find the fault. good luck.

My test rig device is running with 16 to 24 volts 3.5 Amp on this test, (it's a 6 turn winding) and using high-speed IGBTs and even running a 50W quartz bulb nothing gets warm only the bulb.

It sounds like they are overheating due to overlapping of the triggering pulses or they are not turning off fast enough (my guess is they are not turning off fast enough before the other FET is energizing).

Unless he shows us a scope shot or breaks it down who knows ?

Hi all,

While trying out Sergey grenade mod in the lab I had to calculate wire lengths/etc. So I made calculator script (Python) which may be useful for others as well:


$ ./grenade_calc.py
Grenade configuration - alexewsergey mod.
Coil wire length: 37.50m
Tesla Coil(CCW) aluminum wire length: 37.50m
Copper strip(CW) (after Tesla Coil) wire length: 0.94m
Ground wire length: 25.00m
Inductor Coil(CW) length: 12.50m


Coil length: 22.00cm
        L0(CW): 22.00cm, Wire Length: 9.42m                 
        L1/L2(CW): 22.00cm, L1 turns: 60, L2 turns: 60        2.68 x 4  per layer
        L3/L4(CCW): 11.00cm, L3 turns: 30, L4 turns: 30       '' ''   x 2    ''    ''
        L5/L6(CCW): 5.50cm, L5 turns: 15, L6 turns: 15         '' ''   x1     ''    ''
                                                                                  37.5m /14 = 1/4 wave in this case


P.S> Please see akula explanation diagram about where extra energy comes from and what to aim for:

Cheers!

test 1

winding the grenade with a 37.5m length please note I don't think winding 60 t + 60t and 30 t + 30 t and 15 t +15 is going to work I just tried it I ran out or wire at L4 !!! and it's not tuned to anything at all on our test equipment.

test 2

Two of us also tried winding a 'none inductive wind' of 2 layers, that gives you nothing at all in volts just current.

Fun ain it !  ;)

I note the thread has many readers but no one is sharing, if you want to keep it going please share !

Nick,

It is too bad that you got sent the IRFP250 mosfets instead of the IRFP260n mosfets that you ordered. The P250 has twice the RdssOn and a lower maximum Drain-Source current than the P260n.

The P250 does however have lower capacitance  and gate charge values and this will work in your favour.

We really need to see those scopeshots to figure out what is causing your mosfets to overheat, though.

  TK and All:
  I will upload some scope shots when I can. The circuit was working just like I showed in my last video. But, it was still overheating the new IRFP250N mosfets, and producing very little light at the bulbs.  However, right now the TL board is not working at all, so I replaced the TL494 chip, to another new one, but it still won't fire up. So, I'm working on it, and will upload the scope shots when I get it working again.
  I have not forgotten about the scope shots. "They will come",  like Geo says...  or built it,  and,  IT will come.

  I want to replace the driver chips to the bigger through hole ones mounted on some sockets, when my order of the bigger TC4420 drivers gets here. I have the IC sockets, but not the drivers for them. As I was sent the wrong size ones previously, and I have not received the new through hole bigger size drivers, yet.
 In any case, I'm still working on all of this, to the degree that I can work on the circuit, even though I was sent the wrong P250N fets also, instead of the P260N.
   Might be a lot easier just to buy the TL494 board for $7, like Itsu had bought and tested on his push-pull set up, at one time.
Also, a cheap and more efficient DC to DC converter, like Stalker is using on his last videos.

   Verpies:
   I did some more testing last night to see what is causing the TL board to not fire up.
   From my 24v, 10A PS, through the 12v voltage regulators to the TL494 IC, is exactly 12v,  to pins 11, 12, and 8. I also get 5v from pins 13, 14, and 15, which are bridged together. But, no voltage is coming out of the IC output pins 9 and 10, at all. I've tried three new TL494 ICs, but get no output to the drivers.
Disconnecting the 1000ohm resistor to the fet drivers so there won't be any interference if there is something wrong there, makes no difference.
  Any ideas as to what to check?  I'm still using the Pinoy Tech circuit diagram below.

That's OK.
What waveform do you have on TL494.pin5 ?

But, no voltage is coming out of the IC output pins 9 and 10, at all. I've tried three new TL494 ICs, but get no output to the drivers.
Disconnecting the 1000ohm resistor to the fet drivers so there won't be any interference if there is something wrong there, makes no difference.
That's a bad test because disconnecting R3 or R4 also disconnects R6 & R?, which are pull-down resistors (resistors connected to ground), which are needed for a varying signals to appear at TL494.pin9 & pin10.

For this test, it's better to pull out the FET drivers from their sockets than disconnecting R3 or R4.

  The 1000 ohm resistors from pin 9 and 10 to ground are still connected.  The scope is connected to the ground resistor, only, to the ground side of that 1000 ohm resistor, and to the other side of that same resistor which is connected to pin 9 or 10. I've shown how this works this way,  only disconnecting the 1000 ohm that go to the drivers. 
   The TL's connections look OK, no shorts or loose solder points that I can see. This happened while the circuit was running. The problem may lie at the trim pots, perhaps. As it happened while I was tuning with them if I recall correctly.
    Here's a scope shot of pin 13 and ground (ground from pin 1 and 16). It's a mess alright...scope probes are on channel 1.

  OK,  I think that I found the problem,  a possibly faulty electrolytic capacitor C2, a small 4.7uf cap on pin 2 of the TL494. I'll replace it out tomorrow, and see if that takes care of it, as it's late here tonight. Thought I'd let you know, but, in any case I'll know more tomorrow night.

   Verpies, TK, and All:
   I'm still having problems with my new TL494 circuit board. Sorry to say...
   Below is a video that I just posted, showing the scope signals on the GATES, (not the drains as I had mentioned in the video).
   No matter what I do, the fets still overheat when they are mounted, and also the signals get real messy when the Kacher is on.
   Let me know what you think, and any suggestions that may help. As at this point, I don't know what else to try.
