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
