Conical pulse skip DRSSTC
« on: March 29, 2020, 11:48:49 AM »
Almost completed building my conical coil.
Learned allot in the last year hehehe.



Overview of the coil assembly





Skm200 H-bridge



TEDR (modded ud2.5)



Fan control and lockout + softstart




Tank cap



Power distribution + control lights


Saving money for a lathe toroid atm.
Would be a nice addition to the looks =)

Ill post some of the specs and videos later.

A very rare conical coil, I heard they were such a pain to wind that I never tried it :) How was your experience with slipping wire and did you start from the top to let it slip up against that turn?

Looking forward to see the specs, I was just wondering if 2x 2200uF is enough bus capacitance for pulse skipping without serious dc bus sagging?

You also printed a lot of parts for this coil, my favorites are by far the "square-aluminum-bar-to-wood" adapter for fastening the primary platform with! Did you share your models on some 3D printer websites?

Actually dont try it unless you have to much time...
I actually had to build it a couple of times to get it right.

First had lots of internal form arcing...
Before i filled the form up with expanding foam and polyester.

Yeah it was wound from top to bottom. Kinda the only way hehehehe :)

Yeah those caps might come a bit short.
I have some caps with double the capacitance laying arround.
Might be thinking of replacing them.
Coil is working fine so far though :)

Havmt shared any of the files yet.
I might when its finished!
