Design and implementation of automatic voltage regulator

Abstract

This project presents the design of an automatic voltage regulator (AVR) implemented on ATmega microcontroller. Voltage regulation is a critical aspect of electronic systems, ensuring stable and reliable operation. Thus, it overcomes both undervoltage and over- voltage issues. The objective of this work is to develop a cost-effective and efficient AVR solution based on open-source hardware and software. The methodology involves the integration of the ATmega kit with voltage sensing and control circuits to achieve au- tomatic regulation. The implemented AVR system successfully monitored and adjusted the output voltage within predefined limits .Experimental results demonstrate the effectiveness of the design in maintaining voltage stability under varying load conditions. The AVR exhibited an average voltage deviation of less than 5% from the desired setpoint. Moreover, the project discusses the limitations faced during the implementation and proposes potential enhancements for future cycles, such as incorporating advanced control algorithms for improved performance. This project serves as a foundation for further research and practical applications in the fiel do fvoltage regulation using Arduino-based platforms.
