My "super-fancy" SSTC (Terry's characterization, I think--and quite 
accurate; >too< super, in fact) employs 6 paralleled primaries, tightly 
coupled & directly under the secondary.  Worked fine until an intractable 
problem developed.  I haven't summoned up new motivation yet to fix it.

Has anyone explored the use of paralleled primaries in SSTC use.

For example, say I had two SSTC full-bridge power supplies each with
their own dedicated primary winding and of course both supplies
switching frequency are synchronized.  Now i take those two independent
windings and use them either interweaved, or top/bottom configurations
and run both at the same time.

Neglecting losses, I would assume that two 5kW power supplies combined
like this would appear like one 10kW supply to
the secondary coil.  Is this correct???

If so, perhaps this is a way to increase power even more to a SSTC when
the maximum impedance of one coil limitations
are met.

Suppose I had four independent synchronized SSTC drivers with four
independent primaries . . . Hmmm . . . . could
get interesting!
