This is a DRSSTC. I don't have a specific parts list or schematic for
coil, and I'm hesitant to make that information public due to the amount
work I've put into this project. It is similar to Steve Ward's DRSSTC 4
that he has published on his site.
Some notable differences include the larger top load, different
dimensions, and much larger IGBTs. The picture I posted earlier was
the coil using 150A IGBTs, presently the coil is being rebuilt and will
