I suppose if you want to be fussy, the DC will be lumpy every 120 degrees,
but hey, thats what lead acid batteries like being charged by....

Cam..

You mean the alternator on my car isn't
three phase furnishing DC to charge the battery"?

Yes, it is.

It is a 3 phase AC machine - the rectifiers make DC - which is DC no
mater how you slice it and dice it, and no matter what you roll it in.

Actually, no, but I'll let you ponder on the rest of the circuit.
