Hi ,

The readings on scope shots are interesting with the non-dissipative snubber circuit as shown . I wonder what It would do to the device.
gives something like a spike at some point.

Currently modding the Akula Kacher, it looks like the output signals were not perfected as how it should be, my dead time to form nice spike
has to be adjusted ( Collapse time ) , might be that this is limiting me to get more out at output.
Have tried many points of tuning( many harmonics of the same spot) but nothing increased, but last video was best result till now,
it's all about the Tesla coil operation spikes that make the differences .

yes I agree some relevant and important issues brought up here,

Itsu  the 31.25 khz by channel 1 is that the combined output frequency or just the one channel ?

Also as I have previously mentioned The Tesla coil The C5200 device the gain of this device is clearly in adequate on it's own for self oscillating circuits although it might appear to work for some larger coils all tests show it does not shut off or fully turn on correctly as will be noticed in the amount of current it draws and it's over heating.

Hi Itsu. Good video! 

My coils in the non-dissipative snubbers seem to just get warm but not hot at 24V, 
by my coils are maybe using thicker gauge magnet wire on them. I think the wire gauge
is either #20 or #22 AWG. The coils are rated for 1.9A, and specified as 0.28 Ohms.
A coil with a higher resistance would likely show more heating.

Since the UF4007 diodes get hot when using 24V, I think that if anyone wants to
try this type of snubber it would be better to go with Schottky diodes that have a reverse
voltage rating of at least 500V and a current rating of at least say 8A or 10A.
Then the diodes should stay a fair bit cooler, I would guess.

So, with coils made with heavier gauge magnet wire to keep the coil resistance low, and
suitable Schottky diodes it seems non-dissipative snubbers may be workable for use at 24V
without excessive heating.

I am still testing at 24V. I removed the UF4007 diodes and put in 12R06D diodes instead,
as I had some available. They look like they should be OK for use at 24V, but they may still get
on the hot side if running for a long time, but at least small heat sinks can be mounted on them if needed
for running for long periods of time.

The Allega snubber is maybe simpler to implement, and probably workable at 24V for long   
run times if a 10W or higher wattage total resistance is used.


GeoFusion: Thanks for the update.

AG,

Itsu  the 31.25 khz by channel 1 is that the combined output frequency or just the one channel ?

that is for the yellow ch1 only, but i was running at 15.5 or so KHz, so i think the scope was measuring both the spike as the square, so doubling the frequency.


Void,

i did not measure the chokes resistance, but can do that when i try with schottky diodes, but as they do not get hot they seem OK.

How are you doing my friends? Nice to see the team again ready for new discoveries.

I just wonder, why don't you build Verpies lossless design to end this never ending push pull story? It is a rhetorical question. I know.  it is because you love to learn.. But for this specific job, i find Verpies design just what it needs. Lower consumption, no heating problems, clean drains. What else can someone may want?

All the best
