In theory, there are 3 kinds of generator or alternator
that are synchronus, induction and DC.
So the question is why DC excitaion is used for
alternators. The answer is becuase this a synchronus
generator. And that is philosophy of this kind. For example
if you use AC Excitaion it will not be synchrounus but it
will be induction generator
