Itsu,

The only change is the connection of the clamps.



Regards

OK,  i understand now.

I have double checked my setup, but as i use speaker wire which i tagged with tape i am pretty sure i did not mix up any connections.

   Itsu and All:
   Perhaps you can help me out, if possible. As I'm still having mayor problems with my set up, and I can't seen to find the cause. At one time you helped me with my Mazilli circuit overheating, and now I have a similar issue, but with the TL494/Tc4420 drivers.
   To explain how I have things connected:
   I have connected the positive rail of my 24, 10A PSU directly through the choke and then going to the center tap of the yoke. The primary coil of the yoke going out to the center pin of the three pin IRFP260P mosfet. And the negative rail of the PSU to the right pin of the mosfets. Is that correct? Or not?
   I have also connected the 1000k resistor as well as the facing 18v zener diodes between the left pin of the mosfet (gate) and the right pin of the mosfets.
   I also have the MUR1530 diodes going from the right pin of the fets to the center pin. This with the diodes facing me, as well as the fets.
   If needed I can post a close up of my driver circuits, or anything else on the device which may help. I just can't see what I've done wrong. But, this thing has gone haywire, (and me too) even without the yoke connections from the yoke primary to the fets disconnected, to see if the fets stay cool when I try this test, which they do stay stone cold.
  It must be something simple, but I've spent much time overlooking the cause of this frustrating situation.

  Verpies: Thanks for the correction as to the lossless clamp circuit. I may have to make one myself, If I can't get this fet overheating problem solved, before I pull the rest of my hair out. As it is acting like a short circuit, while yet, I can still light some bulbs. But, I have no output on my 3t coil circuit at this time.



  EDIT: Verpies, at one time I mentioned what I had read about the TC4420 mosfet drivers from their data sheet concerning their function of impeding the fets from being both on at the same time. You mentioned that their job was not that, but to add current to the fets, instead.
   Below is the description you posted from the lossless clamp, point #5:
   "Pins #6 of the UCC27511 drivers (U1 and U2) are used to ensure that two power MOSFETs (Q1 and Q2) are not conducting both at the same time. The voltage on pin #6 must be above 2.4V in order for the driver to be enabled (this happens only when the opposite MOSFET stops conducting. This is sensed by R6 and R8)".

   So, I ask you again, is that not the same function provided by the TC4420 fet drivers, besides providing additional current to the mosfets?
   And could this be why apecore's fets are now not firing at the same time, along with the lossless clamp, as they were previously.
   My fets are still both on at the same time, at times. Depending on the duty cycle, and frequency controller settings.
Varying the setting by only slightly on my device, can cause them to both fire at the same time, still.
   
 

Nick,

your setup as you mention it looks OK by me, i have drawn it, see attached.
For now i can only suggest to connect 2 resistors (100K or so) instead of the primary coils and feed them in the middle with your 24V.

You should be able to scope around and see some nice waveforms on the gates and drains without the MOSFETs getting hot.

If that works OK your setup is basically good and we need to check on the yoke / coils to see if they are wired up OK etc.

Make sure your 24V is filtered enough by having a good choke and some electrolytic and film capacitors.

So, I ask you again, is that not the same function provided by the TC4420 fet drivers, besides providing additional current to the mosfets?
They are not the same.  The TC4420 gate drivers do not have an Enable pin like the pin #6 of the UCC27511 gate driver, thus the TC4420 gate drivers cannot be simply cross connected to ensure that both gates are not driven at the same time (causing what is known as FETs' "cross conduction").

But, but it is not even the job of these gate drivers to prevent this cross conduction. This is the job of the signal generator ! (e.g. the SG3525, TL494, NE555, Arduino, etc...)

The main job of the gate drivers is to provide more current for charging the FET gates quickly.

I have cross connected the UCC27511 gate drivers to prevent FETs' cross conduction only because they had the Enable pins available and unused.  It is merely a safety feature in case the signal generator fails, or Miller's turn-on happens, or severe EMI occurs e.g. from  the "Kacher", or some other such catastrophe...
That safety feature is not required for the functioning of the lossless clamping.

And could this be why apecore's fets are now not firing at the same time, along with the lossless clamp, as they were previously.
I don't even understand what signal generator he is driving his gate drivers with and why he gas reversed some windings.
...but if it ain't broke - don't fix it, ...so I'm refraining from negative feedback.

Good day Verpies,

I m using a SG3525 instead of the TL494 due it has more safety functions.

for each channel i use a UCC37322 (non-inverting driver) with ENABLE function using also.
Each UCC is driving a GDT which feeds the gates of the FET's  (and some extra Zener/diode/cap/resistor to create also a negative voltage for the gates)

I reversed the clam windings because connecting inductive loads my fets where firing at same time (as Nick mentioned), driving 12V bulbs it was OK.

I hope you have enough information te clarify why i had to reverse the clams.... and that the original drawing is not false.
Just for information and understandings

Regards

Hi all,

In regards to grenade windings, at least Sergey Alexeew and Dniester used additional winding.
Sergey's additional winding was under whole grenade and direction same as L1 and tuned to half frequency of grenade
Dniester additional winding was between L2 and L3 and under inductor(continued from L2 on same direction until middle then other way around for L3).

You might also test  those combintations as well.

Cheers!

T1000,

Usefull information ,.....  can you make a short drawing or some more specific information.
At this moment i don't fully understand how it is configurated.

Also i m running some S.A. test as Itsu explained, so it would be interesting to see what effect these changes will have.
As soon i have your information i will modify a grenade and post the S.A. shots

What winding is that then, the only winding I have seen that looks like one is the one in the Sergey video under L1 regarding the Adrian Guska device, there is a video where he takes the 'device apart I don't see any extra winding in his windings it's on his youtube channel.

I still have not all details. Just winding direction of extra coil in both cases is same as neighbor layer and the wire length follow same length as L1 in A.S. case and same as L2 in Dniester case. In addition to Dniester winding method the wire from the middle of grenade go straight to end then L3 is made as usual.
In A.S. case he explained only winding direction under L1 and said about that to be tuned to the half wave. Which end go to the L1 I am not sure and is something to find out. And the grenade L1 starts in series to extra winding before going to the ground. Plus one of inductor wires is also going to the ground in his case.

This is a shot off the Sergey device, is this what you mean ?

  I have replaced just about everything, including trying out three new TL494, new resistors, one new driver chip, and both mosfets. All are brand new. I also replaced the 20k pot on the duty cycle controls, with one that I had on there previously which tested ok. A new 20k pot has been ordered, also. I also have a brand new 50k pot that could be used in place of the 20k pot, if needed.
  I also just replaced the 12v voltage regulator, and all its filter caps. Including changing the smaller electrolytic caps it had on, to the 104j caps, as well as all of the 1000uf filter caps.
  As I don't have the new 15v voltage regulator yet, so I'm running the drivers from a separate 12v battery, and the yoke and fets from my 24v PSU.  Still having interference problems, and fets still heating up, even if running them on the 12v battery.

   I now think that possibly because I mounted the voltage regulators on the same board as the TL494/TC4420 drivers, that there is some kind of possible cross interference of some sort going on. As even my hand getting close to the TL chip and duty cycle controller is enough to change the duty cycle settings. So, I just don't know what the hell is going on. And am just about ready to take an axe to the board and whack off the voltage regulator part and it's filter caps from the rest of the PCB.

   Itsu: Thanks much for taking the time to help me out and draw the circuit diagram. It looks like the diagram is exactly how my drivers are mounted and wired on my board.
  I wish that I had bought the TL494 chip from ebay that you had used at one time, instead of making my own. I would still like to order the DC to DC converter, instead of using my own voltage regulators and filters.

  Verpies: Thanks for the info on the drivers not having the same functions circuit. Perhaps that is what I should do and change, to avoid both fets firing at the same time.

   apecore: Thanks for the info on what fet drivers you are now using. Maybe that is the difference between our circuits. Or maybe not. But, it's noted that you were having the same problems, previously. Keeping in mind, that none of the circuits that we have been following may be without faults or missing information.
   I do have another 3 inch yoke which was previously wired and was used for the 12v yoke circuit that I had used previously. This other yoke can be used for the lossless clamp design by Verpies, if needed. When I run out of hair to pull.

Does that circuit have dead time (DT) between flip-flop state?
Did you try primary winding on the yoke with bifilar wires? (the begining of 2 wires to mosfets and the end to the plus)
In worst case scenario you might end up just making new board similar to Geo used... It needs flip-flop + freq + duty cycle control for each channel. And the primary winding on the yoke is bifilar there.

I still have not all details. Just winding direction of extra coil in both cases is same as neighbor layer and the wire length follow same length as L1 in A.S. case and same as L2 in Dniester case.
1- When i m understanding it in the right context...... This is a extra coil outside of the grenade and have same wirelength of the L1 coil?

In addition to Dniester winding method the wire from the middle of grenade go straight to end then L3 is made as usual.
2- I understand...  normal flyback for starting L3

In A.S. case he explained only winding direction under L1 and said about that to be tuned to the half wave. Which end go to the L1 I am not sure and is something to find out.
Is this concerning point 1?.... so length has to be adjusted to half wave or Lambda/2

And the grenade L1 starts in series to extra winding before going to the ground. Plus one of inductor wires is also going to the ground in his case.
3- This point also is related to point 1 and 2?.....seems this extra coil is part of the GROUND wire?....creating half wave (lambda/2) from ground to L1 node.

This creates superimposed standing wave when bouncing to ground point, ... i guess he is using a STAR_GROUND point at his setup where the Null_node (L1) will be.
L6 is in this case the PEAK_node.
And inductor is connected to STAR_GROUND

Just a logical explanation,....  if i do understand it is configured in this way?



Regarding Spectrum analysing of grenades,....i see approx. same peaks as Itsu posted,...... (37.5m/50mm/2.5mm^2 kapanadze grenade)
i guess Itsu hasn't connected one node of his grenade to GROUND and also hasn't completely placed it as a DUT in the whole setup?
This to include the nearby capacitance of the system.
This will have effect on the resonance point.



The attached S.A. shot is from a grenade placed as a DUT and L1 node connected to GROUND.
I modified L4L5L6 in winding numbers in order to increases its LC resonance.

Due this grenade has a wire length of 40 meter its lambda/4 frequenty would be 1.875Mhz.
Without this modification of winding numbers i stay  approx. 200-250khz below the Lambda/4.
Also different connecting strategies will also influence the resonance peaks also.

So perhaps this gives some more inside information about modifying grenade configurations and S.A. shots.

   T-1000:
   I'm using the same type design for the TL494/TC4420 circuit that Stalker is using currently, but with some minor differences, such as the voltage regulators and filters are from TopRuslan 7, and the Pinoytech design for the connections of the TL494.
These changes were because I was trying to improve the original TopRuslan design which apecore also had to change.
   The pinoytech design is similar to how I'm connecting the TL494, and fet driver circuits.  I've posted all those diagrams previously.

  Below is what my signals look like, from the original TopRuslan design, as well as how they look now, similar, after all the changes. Not much difference, no matter what I do. Fets are both on at the same time, depending on controller settings.
