A few DRSSTC Questions
« on: April 02, 2021, 09:52:23 PM »
I am getting the parts together for a medium sized DRSSTC using SKM100 devices. I have e few questions that I haven't been able to find the answers to.

Any inputs are welcome.

First, the breakout point on most coils I see are on the edge of the toroid. It would seem to make more sense to have the breakout on top, like a QCW.
The only reason I can see for the side breakout it that you can get those cool looking ground strikes.

Second, I am wondering if it is a good idea to put an insulating disk (Lexan) over the primary to partially shield it from strikes. I have a strike ring build on
the coil so the insulating disk would not be the only protection.

Finally, I have not been able to find any information about the SKM100 as far as built in overcurrent protection. I know that other IGBJTs have this feature
and need to have surgery to remove a few bonds.

Thanks for reading this far.

Cheers.

I have a polycarbonate insulating shield on my DRSSTC primary.  No proof that it helps.  Shouldn't do any harm unless it gets too close to the secondary OD.
