The AVR provides closed-loop control by sensing the alternator output voltage at the main stator windings and adjusting the exciter stator field strength. The voltage induced in the exciter rotor, rectified by the rotating diodes, magnetizes the rotating main field which induces a voltage in the main stator windings. A self-excited AVR receives power from the alternator output terminals.
