Oops! Then WTF isn't it just using a pm 3 phase with full bridge
rectifier alternator driving a switching converter instead of a
needlessly complicated and inefficiently dc excited rotor field winding
automobile styled alternator then?

Re-reading the OP, maybe it is but the W lead suggests possibly not. I'm
a bit confused as to whether the terminals are those on the regulator box
or on the alternator itself (or maybe even both?)... What was the
question again? :-)
