AVR-AUTOMATIC VOLTAGE REGULATOR. AS THE NAME IMPLIES IT IS
USED FOR THE REGULATION OF VOLTAGE & VOLTAGE BUILD UP
PURPOSES.IT CONSISTS OF (VOLTAGE SENSING UNIT,VOLTAGE BUILD
UP CKT,PULSE WIDTH MODULATION CKT,etc...,).OBVIOUSLY IF AVR
FAILS THERE WILL BE NO VOLTAGE.SO DG RUNS WITHOUT VOLTAGE
AND THERE WILL BE NO LOAD.
