Hi David

If you use a center tapped (CT) secondary transformer (X3) with HV 3ph 
applied to primaries, and tie all CT's together on secondaries, will easily 
make a 6ph output.  12 ph can be also done using delta wired primaries on 
one 3ph transformer bank and wye wired primaries (1.73V ratio on primaries) 
on other transformer bank  Both banks center tapped connections are tied 
together will make 12 ph.  'n' phases can be created by appropriate tapping 
of a extended delta (with wye extension) taps to adjust relative 
phasing.  See North's Transmitter Book (power supplies) at Jim Lux's site 
for more info...

I built a 6 ph high power linear power supply (0-22V @200A) for R&D using 
this method to allow +/-11V referenced to equipment ground (120-208Y 
input), so first method mentioned definitely works...   ;^D
