Design and Construction of a 300-Watts Modify Sine Wave Inverter

Abstract

An inverter is a device that converts power from a direct current (DC) battery
into conventional alternating current (AC) that can be used to operate all kinds
of electrical devices. The design and construction of a power inverter for low
power requirements of an electronics workshop is described. The inverter is
expected to power soldering iron, laptop and a standing fan from a car battery.
The integrated circuits (ICs) and other design materials were chosen based on
their simplicity and availability in most of the electronics shops. From the nature
of the load, a modify sine wave inverter was chosen. To minimize cost and size,
the circuit was designed to operate on a high frequency transformer and hybrid
circuitry. Modules associated to the design were first conducted on MULTISIM
software to ascertain their working conditions before the construction procedure.
The performance analysis of the functional units was carried out and found
working as anticipated with a power rating of 250 watts against the targeted 300
watts.
