Development of an Arduino-Powered PWM Inverter for Efficient Power Conversion

Abstract

This project presents the design and implementation of an inverter controlled by an Arduino microcontroller. The primary objective is to convert direct current (DC) from a battery or other DC source into alternating current (AC) for powering household or industrial devices. The inverter system utilizes an Arduino to generate precise Pulse Width Modulation (PWM) signals, driving MOSFETs or transistors to produce the desired AC output. The Arduino-based control ensures flexibility, ease of programming, and integration of additional features, such as real-time monitoring of system parameters (input voltage, output voltage, current, and temperature), as well as overload and short-circuit protection. The project incorporates techniques to produce either a modified sine wave or a pure sine wave output, enhancing compatibility with various appliances while maintaining energy efficiency. The system is designed with a focus on simplicity, cost-effectiveness, and reliability, making it suitable for small-scale applications, such as powering LED lights, fans, and low-power electronic devices, as well as serving as a backup power source during outages. This project also serves as an educational tool for understanding the principles of inverters and the role of microcontrollers in power electronics. The results demonstrate a stable and efficient inverter system, highlighting the potential of Arduino as a versatile platform for advanced power control applications.
