looking at building a second coil any reccomendations?
« on: January 11, 2023, 01:30:14 AM »
I built a DRSSTC about 8 years ago and have not done much with it lately until now, mostly because I could not use it at home without it annoying the neighbours.
I have however done a couple of public performances with it with great reception and have a friend who has a place I can operate it in front of visitors. I want to build something bigger with a bit more power this time.
Seems IGBTS are not only cheaper than before, but there is more to choose from.

Should I stay with CM300 series? Is there any particular part numbers that are better to go for nowdays? There are quite a few different variants in the CM300 series than I remember at the time.

Spec wise, how large a coil could I go for with CM300s? I need to dig up the specs for my coil, but at the time I think the MMC was only rated at 700 APK, possibly 800, will need to check.
I have been getting by with an 8A variac at 230V mains. Been using loneoceans UD 2.7 and have been getting streamers at least 2 metres long at full power.
Am i better going with higher rated IGBT's to make it more reliable such as CM600 and just operate at lower power?
Also looking at power requirements if I want to run 2 large coils together. Its difficult to run 2 of them if they are drawing 10A each at the wall outlet, that means I need to connect them to 2 individual outlets on a different circuit breaker.
Not sure now others are getting by when running multiple coils, do most people just turn the power down? Could I get a single variac and run 2 coils through it if the outlet can provide the power?

I think you can find many of the answers in my DRSSTC design guide: https://kaizerpowerelectronics.dk/tesla-coils/drsstc-design-guide/ especially look at the IGBT article and check out the table at the bottom for IGBT brick alternatives.

Stay with CM300 bricks or similar like (SKM200-400) if you have nothing more than 230VAC 10A available. A CM600 coil can easily pull up to 20kW from 3 phase 400VAC.

I also have a lot of calculators to help you design: https://kaizerpowerelectronics.dk/calculators/

Yes i have been looking at your page of builds. Quite a good amount of info, I loosley built my last coil based on loneoceans design, albeit a little less powered, but I could upgrade it to a higher power if i upgrade the MMC.
Basically from what I understand, you need to make the coil taller if you want longer streamers, or else they will strike the ground (and ring) more often?
I think I will stick with CM300, since I already have a pair of them on hand.
Whats the most power that you can put through a pair of these? From memory its around 1100APK?
I wouldnt mind making the next coil close to 2M in height, is this too unrealistic from a pair of these?
I can probably push my outlet to 20A peak if i had to, the fuse box has a 20A fuse on here, so it should be able to supply enough power, although I probably would only run at 15A max I think.
