Hi GWA,
Sounds like the same system we had on Vanguards (VC9).
You are correct - generators produce AC (avoids having slip rings and carbon bushes which arc at low air densities and your DC system avoids having to fit expensive Constant Speed Drives etc if you were to use AC electrics). The AC produced was rectified using banks of diodes.
