  Hoppy:
  The heating issue is not due to the smaller heat sinks. I've tried bigger ones such as the motherboard ones, and they worked worse and is why I changed to using the smaller ones that can dissipate the heat sooner. Less than one half minute running is enough to blow my last fets, in last nights testing. Bigger heat sinks will not dissipate the heat in time before the fets blow, as they have more mass but take longer to dissipate the heat from the start. In any case the excess heating is not solved by heat-sink size, fans, or heat sink compounds, as there is way to much heat being produced for any heat sinks to keep up with.
   Itsu used Verpies lossless clamp design, but, he had produced a very poor output at the bulbs, similar to what I'm seeing now.
   Apecore is also now using Verpies lossless clamp system, and 50v input to his Kacher, but I don't really see any better results at his output, as yet. Considering that I can light the single 100w bulb with just my Kacher by itself running on 24v.

   What value capacitor should I try at the TL's pin 5? I'm currently using the recommended 102.
   
   I believe the problem may be in the yoke coils, or connections methods, as the TL494 is producing nice clean signals on its own, with the yoke connected, until I connect the Kacher. But, the heating issue is not due to the Kacher, as the fets will heat up even without the Kacher being on.

  I'll answer your questions later today, as I've got to go somewhere now. 
   My load is a single 100w bulb which works much better than the smaller value bulbs.
   The same yoke/grenade set up could light 4 100w bulbs using the Mazilli driver, and same Kacher circuit, same input source. Also showing a great sync from the Kacher to the grenade. Unlike this type of TL494 circuit.

You are clearly pulling too much current. You could try heavier choking of the 24V supply to the yoke. I had this problem but managed to limit the pulse current with a suitable value high current choke. Have you got good duty cycle adjustment on the scope with the yoke connected and Kacher off? Don't run without a decent load on the yoke secondary.

102 (1nF) sounds about right to me for the right frequency range with a 100K pot, or 103 (10nF) with a 10K pot.

Nick,
I don' t know if you can do or did it alteady but try to compare your mazilli Fet driver (gates) signals with the TL's.

Nick Appcore, Hoppy and all, Suggest you find out what the resonant frequency of your yoke is you will get far more out if tuned to the sharp gain spike you might need a scope and a capacitor or two. But feel free to ignore my ramblings !

  apecor:  The Mazilli driver has been recycled and is not intact, so no, I can't compare the Mazilli with the TL board.
   What size, type, and number of windings are your yoke choke(s)?  As I can't understand how your fets are staying only warm.
How hot do your fets get when using 3 or 4 100w bulbs, while the bulbs are running at use able brightness?

   Hoppy: I am already running two chokes, a one inch yellow iron powder choke, and also a 3/4 inch iron powder core choke, as can be seen in my device images. Even they are getting way too hot, and will melt down their coils insulation coatings if I run them for over 5 or 10 minutes.
What do you suggest that I should I change to? Or, what would you consider as suitable?
Normally one choke is what most self runners are using.
  I have used as many as three chokes on the Mazilli driver to light up 700w worth of bulbs, as I've shown on previous videos. And the chokes did get hot. Way too hot, as well, but the fets stayed cooler than they are getting now, but even then the fets were also getting hot in due time.
  I was hoping that the TL board with it's duty cycle controller would not allow the fets and chokes to get as hot, nor draw so much current, as compared to the Mazilli running at 100% duty cycle.  But, I guessed wrong.

  Anyways, I just bought a couple more new fets, so I'm good to go.
  Waiting for your replies...

If you have chokes that are getting hot your incurring losses most likely the cores are low frequency or windings are badly tuned or windings are too thin note some cores are very low frequency whatever driver device your using it would be a good idea to make sure it's all in tune resonance bbut not all energy should come from the fets otherwise its a switch mode converter.

Nick,

The primary problem is likely to be lack of duty cycle control due to supply rail spiking adversely affecting the TL494. You should see an improvement if you use a separate supply for the TL494 and fet drivers and star ground to the primary power supply. You will need to experiment with chokes once you have gained reasonable duty cycle control. Getting the snubbing right takes experimentation whilst studying the waveforms. As you are finding, its a steep learning curve! As a start, increase the size of your heat sinks and make sure you have good thermal transfer from fets to heatsinks by using new pads or grease.

I just completed my construction of the TL494 + TC4420 halfbridge driver board. Seems to work fine so far. I'm using IRF3205 mosfets and they do not heat up appreciably. IRF830s did heat up more than I like. I don't have any spare P260s to try at the moment. The Base signals coming out of the 4420s have a Fall Time of under 5 ns, which pleases me greatly.
I'm using 400 pF of mica caps for the frequency (Pin 5) with 10k trimpots. This allows me to cover my own frequency range of interest (from around 125 to around 280 kHz or so, single channel). Snubbers are 10 nF + 22R.
No, I do not have the Kapa coil sets made up yet but early testing with some misc. inductive and resistive loads so far have not revealed any major problems.

   TK:
   Nice!!!
   It's easy to see how it's all connected up that way. You mentioned the Kapa coil set up. Is that what you will use the board for?
   I see that you have a newer digital scope now also, not the older analog Tektronics one you were using before, which was similar to mine.
   So, I'm waiting to see how it all works out for you.
   Maybe place a link to some of your newer videos, also, as I see you've got some out on YT.

    Hoppy: I believe that you are right about separating the inputs from the TL circuit and the Fet drivers circuits. That can be the cause of cross interference to the signals. I'm waiting for my new voltage regulators which I've ordered, but in the meantime I connected up an older used 12v regulator to both TL and to the fet drivers, and I do see plenty of interference to the signal between them, connecting both up together in this way.
  I'll will separate the inputs today. As I already know that it will help, and that has been one of my signal issue problems at times, as the TL circuits and the driver circuits, work fine by themselves.
   I believe that I also have found the cause of overheating. It may have been the way that I had my yoke connections set up previously.
So, I'm trying a different yoke/grenade connection set up now, as Stalker has them, and will know more about it all soon.
As my fets only heat up when I connect them up to the yoke/grenade circuits, of course. But, that IS where the problem lies.

   Good luck with your new rig TK. It's good to see you posting your work here with us, again.
   Some of the old timers from here have been posting at OUR forum, but I don't see much positive results going on over there, or anywhere else, for that matter.
                               NickZ

Thanks!

My new videos aren't really relevant to this thread, but this one may be of general interest anyway, especially since it has gotten my trolls to post their 5 thumbs-downs already:
http://www.youtube.com/watch?v=ChV7n0EY2h0

Meanwhile, I've been testing the 494 driver board using a small pot-core stepup transformer and a neon as load. I'm either connecting one end of the pot-core Primary to both drains and the other end of the Primary to the positive supply rail. Or, I'll connect each end of the Primary to a Drain and the Center Tap of the Primary to the positive supply rail.

In the scopeshot below CH1 and CH2 are the Gate signals from the twin 4420 chips, and CH3 is the common Drain signal using the first potcore hookup. (Remember Drain goes LOW when mosfets are ON). I have found that tuning can be tricky, in that sometimes one or the other of the 494 outputs collapses to a spike instead of a rectangular pulse. This may present a problem if one tries to tune without using the oscilloscope.
 
The Drain Snubbers using 22R 2W + 0.01 uF 1kV  are working well to absorb nastiness that could heat up and or damage the mosfets. I'm using IRF3205 mosfets and they are working well with the loads I have tried. Have not damaged anything in several hours of testing in all kinds of load conditions and current draw. (I have my PSU set to limit current at around 3 amps though.)

I have also installed a switch whereby I can select one of three different Timing Capacitors so I can cover a very broad frequency range. (Not shown on the Layout diagram.)

This is basically the Stalker circuit with the addition of the 1k pulldown resistors for the 494 open-collector outputs, and the Snubbers on each mosfet Drain, and the switch for Timing Capacitor choices.

An additional approach to FE/CE development - the (b) method?
« Reply #17232 on: May 23, 2017, 02:01:11 PM »
Posted the following in another form a few days back but it is likely relevant here as well. Food for thought!

 F.Y.I.
 
 In the real world progressing from a great idea to a viable product, believe it or not, can be
 relatively easy, a lot of fun and quite interesting. Developing a "new type of fuel-less generator"
 has an added bonus in that it can be done semi-professionally at relative low cost.
 
 Briefly, an example scenario:
 
 There are two development roads one can follow. Either the (a) iterative "cut and try" method, or,
 what I'll term, (b) the mathematical engineering physics route; or preferably a healthy slice of both
 (a) plus (b).

 
 Following only the (a) road, in my opinion, is quite valuable but quickly leads to a brick wall dead
 end. Youtube is littered with videos of coils and light bulbs including, in some rare cases,
 researchers attempting to educate other "seekers-of-knowledge" using a variety of primitive "aids" and
 "self derived" gibberish. Out of the many thousands of videos and comment pages there are but a hand
 full of "useful" demonstrations; and, more often than not, when their goal is reached the presenter moves
 on to further (usually very quiet retirement) development. Without the (b) route there is generally not much in the
 way of "value" to be had. We have all observed this over the years. I will address (b) further in a bit.
 
 Physical Hardware and T&M Equipment:
 
 Device hardware; that is, for wire, electronic components, brass-board, enclosure, and so forth the expenditures
 are minimal; likely less than a dining out for two with desert and drinks!
 
 Fundamental design Test Equipment; an old laptop, (isolated) USB PC Oscilloscope, digital meter,
 and battery again can be procured now days at very low cost. High voltage probes and other exotic
 measurement devices can be easily fabricated with a little ingenuity.
 
 Engineering Physics Tools (mathematics - multiphysics Computer Aided Engineering [CAE]):
 
 Much, if not all, of the "alternate" energy theory, in my opinion, can be uncovered and disclosed
 using conventional science with the assistance of modern engineering and physics tools that
 are just now becoming available to us; the (b) route . Here are a few of the many examples:
 
 Simulation Software: A Price and Performance for Everyone
 
 Multiphysics for the masses. COMSOL wants to democratize simulation in the design process– TV-report > ENGINEERING.com
 
 https://www.comsol.com/products
 
 Gaining access to these tools can be cost effective as well - take a course at your local educational
 institute; invest in an "off lease or surplus" HP Z820 Workstation; obtain demo or student versions
 of CAE software; put a business plan together and run it by your banker or rich uncle... A maybe "unseen
 additional bonus" involves developing a valuable "skill set" that can be applied in many other disciplines.
 
 There is enough valid evidence of viable alternate energy devices but to make it actually happen
 we need to do something besides light bulbs on Youtube, bicker about who's theory is correct or
 what "method or technique" is the best.
 
 With minimal expense and a little diligent effort, I firmly believe following the (b) route will bring
 success for all and, if not right away, it will be fun and very educational at worst.
 
 Plus; I see enough intelligence out here, I'm optimistic we can do it... we do however need a
 forum board where you can publish formulas and other science material in a usable fashion.
 
 Thanks for reading
 PS - My new 32 core servers arrive tomorrow so I too will now also "move to a very quiet retirement" [development].
 
 FIN

For many on the fora, tinkering around with electronic components and associated test equipment and software to develop skills in practical electronics is the primary source of enjoyment. The assumed primary purpose for doing this - to build a free energy device - for many, eventually becomes of secondary importance I would suggest.

   However, as fun or educational as tinkering with electronics may be, it would really be nice to build a self running device that works. Instead of spending thousands of hours, months and years, without anything useful to show for it. Some positive results would also provide us with further motivation to continue in the future.
In any case,  I'm dedicated to this cause, and will stick with it, come hell or high waters. As that is what I came to this world to re- discover, re-invent, and improve apon, once it's working.  And I will get it working.
   Thanks to all for your help and cooperation. We are a team, and a good one at that. Regardless of results.

  TK:  I'll study your circuit and get back to you on it a little later. Thanks for posting it.
