Description

project report covers the design and implementation of a single-output inverter. It converts a single 12V DC input to a 70V AC output at 7watts using Arduino-controlled MOSFETs. This setup is cost- efficient because one inverter can supply different loads, saving money and space, especially in renewable energy systems. The goal is to develop an inverter that provides multiple AC outputs from one DC source for various uses, including renewable energy and portable power supplies. The core of the system is an Arduino microcontroller. It generates precise pulse-width modulation (PWM) signals to control the MOSFET switches, ensuring efficient conversion and stable output. The design process involves choosing the right MOSFETs and developing protective circuits to prevent overvoltage, under voltage, and short-circuits. Experimental results show that the inverter can produce a stable 70V AC output with low harmonic distortion, maintaining performance under different load conditions. The system's efficiency, output quality, and response to changing loads are thoroughly analyzed. This project demonstrates the effective combination of Arduino control with power electronics, providing a high-performance solution for converting DC to AC power.
