what is AVR and tell principle and working?
Answer Posted / austin kpoto
AVR, automotive voltage regulator, important principle AVR,
exciter, when rectifies rotate induce voltage in excitation
motion. AVR, support the control system in three main ways
1.sence volts that moving to the main armature.
2. Supply current to exciter field in the in the generator.
3. AVR, will continue to function until generator maximum
output.
