ABSTRACT
The AVR is an automatic voltage regulator and it is a device which
is used to regulate or stabilize electrical power supply for electrical or
electronic appliances.
Inthisprojecttherefore,weareinterestedintheconstructionof
this allimportantdevice.Furthermore we shalldiscuses the
techniques,processes,switching stages and then the working
principleoftheautomaticvoltageregulator
