Cutting edge as usual. Yeah. I built. Tweaked, modified his mini the year he designed it. I didn't use a 555 kick start on mine, the enable pulse was sufficient to start oscillation. It's amazing how much I learned about solid state switch mode power supplies from those sstc circuits and so many other concepts.
Well, I actually melted those secondary coils eventually so now I have forced air cooling with an acrylic sleeve to keep the air flow over the winding.
Looks like you're getting arcing out of the secondary of the right fat coil. Have you tried sealing the secondary, treating it as a chamber, and using dialectic oil? I've also used a thick polyethylene coating with a 1/4" poly carbonate tube that slides over the secondary. That seems to help in the higher frequencies.
That breakout was a mosquito. I now use acrylic pipe around the coils to act as additional insulation. I blow air through the pipe to cool the coil, as well.
@@SteveWard Very Nice. It seems that you've solved the racing arc issue as well from your latest experiments with the dialectic shielding. Any tips or resources on creating a cleaner ramp power supply? Seems like this project is producing more consistent and smoother ramps.
Hey, I'm working on this project that requires high voltage 3 phase outputs from something like a Tesla coil. I'm sorry to ask, but may I have a copy of your schematic so that I may replicate this circuit please? Thank you
How can I contact you? Curious to know more about your application. The brains of the operation on the 3p Tesla is just an STM32F4 microcontroller with some phase current feedback to help it adjust it's output frequency to maintain ideal switching load conditions for the 3 half bridge circuits. The ideal switch freq is above the coil's resonance, just slightly, so that the load appears inductive rather than resistive or capacitive.
@@NerdyNEET it's actually double resonant with only partial primary resonant boost due to detuning. The additional switching losses from frequency modulation are not very significant to total efficiency and it doesn't require extra hardware for modulation which is more attractive to me for a higher density design.

oh my word i wanted to always see one like this. thank you.
Beautiful. White electric flames with smaller purple discharges. Well done.
What the secondary did on the right was wild!!
I think that was a mosquito!
Oh wow, this is absolutely amazing! Thanks for sharing!
Awesome stuff! I’ve built your mini sstc and it works great!
This sheer amount of power is absolutely insane! Don't know how you're keeping your secondary coils cool

This is awesome, nice work Steve!
OMG!!......very well done!! WITH BPS CONTROL TOO!?!?👀👍 AWESOME COILS!!
It must be the biggest fly swatter we've ever seen ;-)
Wow... 😲
Subscribed!
You going to open up the portal bro
i was thinking of building this with 3 full size 4 in or 6 in coils driven by utility three phase with the original circuitry used by tesla himself
any thoughts?
Beautiful!
Hmmm. Interesting coincidence). Just the other day we finished testing a quad system, with alternating phasing. Draws a square ...
Sweet!

@@SteveWardAlso can't wait to see some more bass playing with this!
Awsome TC ;)

Tuch the sparks
That's SiC(k)!!
Could these be run fully CW ?
When I get brave enough, I have a 440v 150amp battery available to power it.
@@SteveWard Can't wait haha! Happy New Year :)
This is crazy, what is the maximum pulse length?
Few hundred milliseconds. Could try CW I suppose.
How much power does it draw? About 20-30 kW peak?
Maybe not peak, but average :D

My car needs more power for the spartan plugs.
Whuuuuuuuuut
Beautiful!
