RE: AVR
The AVR measures the terminal voltage and through some form of singal conditioning and amplification it produces a current output. Some AVRs are based on a permanent magnet generator (PMG) to provide the power to the field, others use the main output of the generator for their power. Some have a rectifier on the shaft, some pass DC from the AVR through slip rings. Some use a signal of a few amps to control a pilot exciter and main exciter which in turn feed the generator field, others directly deliver perhaps 6000A directly to to the main generator field. There are a lot of permutations!
In the machine you're considering in your other thread it's a fair bet that it uses a PMG and a rotating rectifier.
