ABSTRACT

The automatic voltage regulator AVR) technology have been modify to what. is obtainable today, in today's world of civilization technology are virtually -the frame-work on 'which civilization has evolved, electricity charges is the backbone art which technology strives. It is on {his note that electricity charge generation, distribution, and transmission requires a device to improve stability, making it reduce over voltage on loss of load and better system voltage regulator. Automatic voltage regulator is designed with electronic control circuit technology eliminating voltage surge and fluctuation to bear minimum, having, powder supply AC regulator where by it input mains are regulated with a comparator which fed the drivers controlling the relays that charge the taping of the autotransformer in the system, it is necessary to develop the electronic control system which regulate power input in a device or system, and is widely used in electrical power field to obtain the stability and' good regulation of the electric system. The main objective of these project work is to modify the AVR technology, construct circuit with improve overall effectiveness, these include a more accurate measurement of voltage and current, as well as improving the response time and stem stability of input fluctuating voltage from 16volts to 230 giving a regulated output voltage of 23L± L5V.
