160mm DRSSTC project
« on: January 10, 2023, 11:54:15 PM »
Hello everybody,

For a long time, I always wanted a DRSSTC but it was unimaginable for me to build one.
A few months ago I built my first "little" DRSSTC to begin, which I never would have thought of when I was 12.
Now that I've built a little DRSSTC to understand how it works, and have fun, I am embarking on a project that I would love to do for a very long time, a fairly large DRSSTC.

Since it's a pretty big project, I started doing CAD design to see what it could look like and avoid as many mechanical problems as possible.

Here are the plans I was able to make with SolidWorks :





The box should be 46x25.5 cm (not counting the wheels and the primary support).
The entire DRSSTC should be about 1m40.

Some specs :

  • Toroid: ~150mm minor diameter, ~700mm major diameter
  • Secondary : 160mm, 73cm winding with 0.315mm copper wire
  • Secondary frequency : 74kHz
  • I don't know yet exactly how the MMC will be (maybe Dawncap 3000v 0.47uf in 5s2p configuration)
  • For lGBT, I don't know exactly, maybe cm300 or skm300 depending on price and availability, I do not know yet if I make it work in 325v or with a voltage doubler in 678v
  • for the controller I will surely make the UD2.9 of profdc9
  • Bus capacitance: maybe 2x6800uF (or 6800uf with the voltage doubler)

I have already started a little, starting with the secondary circuit,
Here is some photo:



I will try to start making the aluminum case, and of course I will post the progress ;D !

Only concern that comes to mind is aluminum case top ring looks too close to primary coil.  See this post and many following ones related to the same issue with a large coil:
https://highvoltageforum.net/index.php?topic=1430.msg11047#msg11047
Top of aluminum frame makes shorted turn.  Issue in above link is that 8020 is anodized, so has a thin nonconductive coating on sides.  Initially frame top isn't quite a complete shorted turn due to this anodization.  Arc from secondary broke down this thin oxide layer.  Then the much higher current induced from primary coil melted screws.

Great material and looks like you are well prepared for building a coil like this :)

I think you should add longer legs from frame to platform that supports the primary coil. A total height of 140 cm for a CM300 coil, that can easily do 2-2.5 meter sparks, will just give you a lot of ground strikes and not take advantage of such a powerful bridge.

Your wheels on the base is going to give you stability problems, the foot print is simply not large enough for something that is this tall. I have made the same mistake on both my DRSSTC 1 and 3. For my large coil I simply had to build a support frame of 4 pieces of 2 meter long wood frame, to give it a large enough foot print. Somehow there is never a even surface where you are going to run a Tesla coil, as its mostly outside :)

A 5s2p MMC of 0.47uF capacitors is only going to net you around 0.188uF, that is too small for such a coil, in my opinion. Did you take your design for a ride in the MMC calculator? https://kaizerpowerelectronics.dk/calculators/mmc-calculator/

In my guide, I recommend 0.3 to 0.6 uF for a 160mm coil https://kaizerpowerelectronics.dk/tesla-coils/drsstc-design-guide/mmc-tank-capacitor/

I originally wanted to insulate the upper part of the chassis like the brOdin coil, but that's a good idea, I would put longer legs from the frame to the platform that supports the primary coil to gain some height, and to avoid problems with the primary coil.

I suspected that the MMC would have too small a capacity, I would try to make an MMC in this range of 0.3 to 0.6uf.

Thanks for this information, this can indeed be quite an annoying problem.

I started to look at how much it could cost me to make the UD 2.9 of profdc9, but I noticed that it works in pulse skip, I also looked at the UD 2.7 of profdc9 and it would cost me almost the same to do the UD 2.7 (without pulse skip) or the UD2.9 (with pulse skip).

I wonder if it can be a good idea to make the pulse skip controller, or I keep it simple with the UD 2.7.

The pulse skip mode really brings a plus for this coil size ?

I imagine the pulse skip mode adds maybe more stress on the IGBTs,  so maybe it's better to stay with UD 2.7 ?
I don't know at all if it can be a good idea to use the pulse skip mode, what do you think?

I also started looking at the IGBT bricks, after looking at the table on the IGBT page (which is very useful !) : https://kaizerpowerelectronics.dk/tesla-coils/drsstc-design-guide/igbts/
I saw the CM300DY-24H bricks which I think might work well with my setup, I read several threads on where to buy IGBT bricks, so I looked on eBay for IGBTs and found several sales, one of which I spotted: https://www.ebay.com/itm/282631487695

I also looked at the SKM300GB125D: https://www.ebay.com/itm/322570650877 but I'm thinking of using the CM300s

Are there any special things to pay attention to when selling IGBT bricks ? Are there many counterfeits ?

Hey,

Im not sure if theres a better way to do this but i would be happy to sell you 2 cm300dy-24h bricks for nearly half that price, I can confirm they are genuine as well.

Most bricks on ebay will be genuine but make sure they are functional and also not in too poor condition.

Kindest regards,
Davis

Thank you for the answer, it's an interesting offer, but the problem is that I live in France so I think the shipping can be very expensive :-\

Nice work so far!

Are you planning CM300 half-bridge or full-bridge?
Check out my similar 160 mm coil https://www.highvoltageforum.net/index.php?topic=78.0
I'm using SKM400 half-bridge with 340nF MMC, originally I had CM200 half-bridge and both worked great
 

I would suggest you use CM300 half-bridge with voltage doubler for your coil, especially with 240 VAC mains here in Europe
Mine survived 7 years of occasional use and I'm sure the inverter won't fail anytime soon. I recently rebuilt it, changed DC power supply and rewired everything- now I'm waiting for some good weather to test everything out

Very nice DRSSTC ! Interesting way to cool IGBTs

I planned to make a full bridge with two CM300 which will maybe CM300DY-24H.
