Answer / austin kpoto

Derived from a closed loop system from alternator, when
exciter rotate rectifer induce dc voltage. Exciter diode
convert dc current from diode to rotor main armuture to

alternator.Poles turns produce minus and plus sign from
main armature than alternator send dc current to AVR.
