DESIGN AND CONSTRUCTION OF AC VOLTAGE REGULATOR/STABILIZER

DESIGN AND CONSTRUCTION OF AC VOLTAGE REGULATOR/STABILIZER

This project is titled the design and construction of an AC Automatic Voltage Stabilizer. It is designed to meet up with the AC voltage safety, stability and accuracy demand in industries and in homes. Voltage stabilizers are useful in devices such as computer Power supplies, alternators and central power station generator plants, voltage regulators control the output of the plant. In an electric power distribution system, voltage regulators may be installed at a substation or along distribution lines so that all customers receive steady voltage independent of how much power is drawn from the line. An AC Automatic voltage stabilizer is designed to automatically maintain a constant AC voltage level. An AC Voltage Stabilizer may be a simple “feed-forward” design or may include negative feedback control loops. It makes use an electromechanical mechanism, and other electronic components. Depending on the design, it may be used to regulate one or more AC voltages.
This project is designed to stabilize an AC input voltage of 160-250V to give an AC output voltage of 240V at 50Hz automatically. The automatic feature can be achieved by the electronics devices used such voltage comparator IC, electro-magnetic device (relay), auto- transformer and other electronics devices. In this project, an automatic ac voltage stabilizer was designed to control and stabilize an AC input voltage of 160-250V to produce an output of 240V all at 50Hz.
