Design of DC-AC inverter using microcontroller PIC control

Abstract

This project aims to design single-phase sine wave DC-AC power inverter integrated with a microcontroller (PIC16F877A), simulated by using proteus software and implementation inverter circuit and discuss the result to output AC power quality an input DC power supply. It involves generating of unipolar signals using programming to Programmable Interface Computer (PIC) and hex inverter. Control on output to use them to modulate a 12 V DC to 230 V AC with stable frequency (50 Hz). The focus is on designing inverter system is an inexpensive, more stable, high efficient system and smooth sine wave inverter because of the reliability of power company electricity service varies greatly due to many factors including the design of the power grid, protective features, power system maintenance practices and severe weather and availability of renewable energy sources . The results of simulation were successful results of inversion.
