Design And Construction Of 1KVA Automatic Voltage Regulator (AVR)

This project, titled “Design and Construction of a 1KVA Automatic Voltage Regulator,” aims to develop a device that ensures AC voltage safety, stability, and accuracy in industrial and domestic settings. Voltage regulators play a crucial role in various applications, including computer power supplies, alternators, and central power station generator plants, where they control output voltage. In electric power distribution systems, voltage regulators are installed at substations or along distribution lines to provide steady voltage to all customers, regardless of power consumption.
The AC Automatic Voltage Regulator designed in this project maintains a constant AC voltage level automatically. The design employs an electromechanical mechanism and electronic components, including voltage comparator IC, electromagnetic device (relay), auto-transformer, and others. The project aims to stabilize an AC input voltage of 160-250V to produce a stable output of 220V at 50Hz. A 1KW capacity was designed to achieve this voltage control and stabilization.
