This project is on Design of 2.5kw automatic voltage regulation with seven segment display. The automatic voltage regulator with seven segment display is a design or circuit that monitors the input voltage at any point and display the regulated voltage level on the seven segment, It is very important for the electrical/electronic system that is delicate to an abnormal voltage level. It is usually connected as an intermediary between a voltage supply and appliance. The project Automatic voltage regulator with seven segment display includes a transformer, voltage sensor called comparators that is connected to the power source for sensing voltage level of the power when it is low or high and a processing device connected to the voltage sensor for comparing the sensed voltage level to a reference value. The seven segment display unit is been connected to the processing device that sensed voltage value is less than the reference value.
