AC INVERTER FOR AUTOMOBILE

Abstract

"In automobiles, the electrical and electronic accessories are supported by the car battery. The type of AC inverter developed will generates from a input voltage of DC12V battery loaded on a vehicle body which drives a motor to an output voltage of AC230V, enabling electric appliances such as laptop, mobile phone, electric light, digital camera, DVD player, TV, fan, radio and other electric apparatuses to be used in automobiles.

This report will provide a better understanding of the DC-AC inverter for automobiles. There are mainly two major classifications of inverters, external and self-commutation techniques. The basic principles of DC-to-AC power conversion using power electronics inverter and the current and voltage control techniques are also explained. Different types of inverter topologies are also described with their operating modes.

Testing and troubleshooting of the constructed PCB board is made possible with the aid of NI ELVIS software. The software will allows an adjustable DC input voltage to power up the circuit and thus enabling easy capture of the output waveform. The overall schematic shall be mounted together with the power transformer to step up or step down the voltage required which is enclosed in a chassis. "
