@mgpwr: OK< ty.

The high-frequency output from secondary, using LF input from primary, is probably due to resonant ringing, and to get this to work properly the secondary must be loosely coupled magnetically to the primary. This is how Tesla achieved HF outputs from his LF spark-gap-interrupted primary supply. The idea is this: the primary drive circuit produces a fast risetime and falltime short pulse at a relatively low frequency. This causes the secondary to ring at its higher frequency of 1/4-wave resonance and allows VRSWR (voltage rise due to standing wave resonance). Like striking a bell with a hammer. A single strike produces a lot of vibration cycles in the bell. If the primary is too closely coupled to the secondary this causes the secondary to induce back into the primary and damps the resonant rise. If the secondary and its associated capacitance are carefully built for "high Q" then there is little or no decay of the secondary ringing, until the next LF pulse comes along from the primary.
But this is different from the way modern solid-state TCs work, where the primary is pulsed at the same HF rate as the resonant frequency of the secondary. So you get a primary pulse and a secondary sinus cycle, just one, and then another primary pulse comes along. In this setup the primary can be much more closely coupled to the secondary since you aren't worried about mutual damping.
I think the circuits you are working with are trying to do the first, older Tesla method of pulsing primary at a relatively low frequency with short pulses of fast rise and fall times, and allowing the secondary to ring freely at its higher quarterwave resonant frequency. So you might try actually reducing the electromagnetic coupling constant "k" between primary and secondary. Also think about "Q" of the secondary and try to maximize that with careful construction and low-loss components after the secondary output.

Just my "two cents worth" based on my experience with TCs and SSTCs and drive circuitry. Good luck!

hi TinselKoala,

I have managed to come up with this visual presentation which i have drawn in around 10 minutes.
This is how i correlate the singing bowl with kapanadze coil base on the result i have achieved.

Please see attachment.Maybe only a Physics Prof can understand the visual inner working of kapanadze coil.

--------------------------------------------------------
The above concept is similar to the Akula first self-running but unstable device without Earth which was presented in his backyard.

The internal tank coil of the earlier device was set at around 150khz for the kacher\tesla coil and the mini kapanadze coil in the middle of the pvc pipe.
But the applied frequency was exactly 1/3 of the tank circuit which is approx 50khz.

For the older device if the pwm was functioning at 50khz using inverter supply 220volts.This cause the let call it "tank circuit" in the middle of PVC pipe to resonate at it's resonance frequency say 150khz.
Matematically both this frequency 50khz and 150khz needed to be in sync if we are taking about 3rd harmonics.

My only theory related to the older Akula device-
Why Akula previously mentioned the older device was unstable was because of dift in resonance frequency or pwm frequency likely cause by drift in capacitance within capacitor whenever there is change in capacitor temperature.

The only way to solve the frequency drift problem even for pll base circuit is to use "Mica capacitor" where frequency stability is highly "desirable".

---------------------------------------------------------------------------
There are other topic i would like to discuss like "Dave Lawton circuit" HHO presented in my youtube years ago where my knowledge in pll was limited back then.
Related to the pin 11 and pin 12 resistors to use for maximum HHO production at pll resonance and getting circuit lock indicator led to be lit.
But time is limited for me to focus on HHO and space constraint,safety.

Since you have worked with pll...

That's all for this weekend..... :D time..... :(

Also; some/many of the technical details (including the mathematics) are given in the links
below, including several instructive Mathcad based animations. These will assist in detailing
the design analysis and engineering...

F.Y.I.

Combining several recently posted "information sources" might assist in
an increased understanding of the concept of FE - CE, BTG, over-unity
(call it what you will). These are postulations presented by their authors but
their theories, IMHO, are quite viable and the empirical references tend to
bare this out.

- http://gorchilin.com/articles/?lang=en the entire site, including Calculations,
and, in particular, these two papers:

- http://gorchilin.com/articles/free/magnetic?lang=en parts 1, 2 and 3;

- http://gorchilin.com/articles/energy/pull?lang=en

- Vasiliev's book (see post #16635 or #16636 in this thread); the entire book,
but in particular Chapters 12 and 19.
http://overunity.com/12736/kapanadze-cousin-dally-free-energy/dlattach/attach/162249/

I repeat these resources again since this valuable information may
have been missed or overlooked
...

The rewards will be well worth the time you spend reading and
comprehending the concepts presented!

I could simply regurgitate simplified portions of the material here but that would, in my
opinion, be counter productive and likely quite confusing. The authors have done a much
better job in detailing their assertions than I could do in a piece meal fashion on this thread.

Have a productive day and all the best...

Since it might be easy to overlook the importance of pulse
generated harmonics and how they relate to the overall operation
of the Standing Waves; Gorchillin also provides some underlying
theory and interactive calculation animations in his "Calculations"
section.

   It does look like the same or similar type of TL494 circuit as what I am working on. Adrian's push pull driver, (first blurry image below). 
 
   I've got my TL 494 push pull circuit connected up and running.  But, it's overheating the mosfets,  big time. Any ideas as to what to do about it.

Nick, can you please refresh my memory as to the following:

1. Are you using pulldown resistors on the pins 9 and 10 outputs of the 494, as in the Stalker schematic up above?
2. What is the value of the Gate resistors between the driver chips and the mosfet Gates?
3. What is the value of the resistors between the 494 outputs and the driver chips?
4. What is the voltage you are supplying to the gate driver chips, and where does it come from?
5. What is the part number of the mosfets you are using?

Can you post a scopeshot of the mosfet Drains, one on CH1 and the other on CH2, probe grounds to the common Source connection? (I'm assuming here that the Source connection is a true ground and you won't be creating a dangerous groundloop by connecting your probe grounds here.)

Mosfet overheating can be caused by a number of things but the most common is that the mosfet is staying in the "linear conduction region" too long and not switching fully ON and OFF hard enough. This can be caused by not enough Gate drive current, too short duty cycles, wrong mosfet for the job (too high Rdsson, too high gate capacitance, etc).

Yess, but this 60hz source would have effect on TC output coil?, this is possible right? :D

I'm afraid I can't answer that, because this is the first time I've seen that connection used. I can tell you that in normal Tesla coils, you definitely do NOT want the mains power supply connected to the secondary as this can be very dangerous to people and equipment.

   TK:
   I did find one thing that I did which may cause the mosfet overheating. I connected my 1k snubber resistor as well as the the 18v zeners before the 10 ohm resistor, and they should be connected after that 10 ohm resistor.
So, I'll correct that, first. And see if that helps with the overheating, or not.
  My push pull driver and snubbers are like the Stalker diagram that I posted just a few posts ago. His latest version,  same as the diagram below.   I am leaning on Stalker approach, as it's simpler, using only a barebone component count.
   I am using the IRFP260N MOSFETs. And I added MUR1560 diodes between drain and source, although it's hard to see them in the picture.
  Thanks for your help.
  I'll post another video when I get things working better, and show some scope shots also.

@Nick:
OK, that will make some difference I'm sure.
But...
1. Are you using pulldown resistors on the 494 output pins as indicated in Stalker's schematic? This may make a difference by assuring that the pins of the 494 turn off hard and fast.
2. Note that Stalker's schematic specifies IRF3205 mosfets. The ON state resistance of the P260n is 0.04 ohms and it is rated at 50 amps maximum. The 3205 has ON state resistance of 0.008 ohms and it is rated at 110 amps maximum. In your application with snubbers I am not sure whether the difference in maximum drain-source voltage is going to be significant (200V for the P260n and 55V for the 3205.) But the difference in the On-state resistance is significant: at the same current, the P260n will be dissipating a lot more power (getting hotter) than the 3205 would.
3. All that notwithstanding, how hot is too hot? The p260n may be getting hot to the touch but I've tested these mosfets and they have no problem running at over 100 degrees C (boiling water) as long as the heat is properly removed. You could try bigger heatsinks and/or fan cooling.
4. I still don't know the value of your Gate resistors between the drivers and the gates. (I'm not talking about the snubber network). I can't read what it says on the photo of Stalker's schematics. These resistors should probably be 10 ohms, certainly not greater than 100 ohms.
5. The MUR1560 is a good fast high-current diode, I use them a lot myself. I'm not clear, however, how this works when used in addition to the snubber network. Maybe someone with more experience can help out here.

Are you talking about this ? You also need large electrolytic and 100nf caps close to Fet drivers as they need to pulse large amounts of current driving capacitance loads 4.7uf is just not enough and keep wiring down to a minimum. As previously mentioned, you also need to drag the high voltage 'pulses' away from those HexFet devices. ( push to shove) personly Fast IGBT's would work far better in that placement and changing the 12v drive reg to 15 volt.

   TK:
   I'm using 460 ohm resistors from pin 9 and 10 to ground. And a 10 ohm resistor from those same pins (9,10) to the fet drivers.
As Verpies mentioned that the diagram which is showing 1k to ground is too much resistance, so I am using the 460 ohm to ground.
   Gate resistors between the drivers and the mosfet gates are 10 ohm.
   The fets are untouchable in 10 seconds running. And will melt their solder points in about 2 minutes running. But, I don't let them get that hot.
These are the same fets that I had on the same heat-sinks for the previous Mazilli/yoke, grenade driver, and they did not get so hot, then.
   The output at the bulbs was much better on the Mazilli circuit. As I have it now, there is very low light levels using one or two 100w, 110v bulbs as the load.
Which look similar to what Itsu had shown on his last video. Low output at the bulbs.

   I'll make the changes that I mentioned previously to the snubbers, and report back.

   Gyula:  Thank for adding contrast to the diagram.  Good to see you posting here, again.

Any ideas as to what to do about it.
Here's a couple of pics of my set up as it looks right now, (2nd and 3rd images) below.
I'd need a 2-ch scopeshot of the drain current vs. drain voltage to be able to see what is stressing your MOSFET (look at Itsu's videos how to take them).

4. What is the voltage you are supplying to the gate driver chips, and where does it come from?
Good question.  The "Stalker" schematic seems to show a +15V regulator on the TC4420's supply rail.

Note, that the 12V Zener diode string at the MOSFET's gate will break down at 12.6V which is 2.4V lower than that +15V supply rail, suggesting that these Zeners are conducting in every cycle (only the 10Ω resistor is limiting their current).
A Zener current scopeshot would reveal that.  Gate voltage would be interesting, too.

... I added MUR1560 diodes between drain and source, although it's hard to see them in the picture.
5. The MUR1560 is a good fast high-current diode, I use them a lot myself. I'm not clear, however, how this works when used in addition to the snubber network. Maybe someone with more experience can help out here.
Such diode placed in antiparallel with the MOSFET (D-S) would only augment its internal body diode.  This makes sense if the external diode is faster and has a lower forward voltage drop (VF) than the body diode.  Does it?

All this correct as you go reminds me of a build it yourself colour TV, witch is what the designer was in fact dooing, In the end I dad to get expert help from a supply and fix the dam thing myself with their help re Uni degree.

The other thing is the duty cycle or dead time which are totally different!!! and they do different things, which is it ???
