AvR is automatic voltage regulator.It controls the voltage being fed to rotor to get required voltage(rated). it uses feedback system to get the set voltage.

Main advantage of auto transformer over two windings transformer is that A it needs no cooling B it uses only one winding C core losses are reduced D it has simple construction
