DESIGN AND CONSTRUCTION OF A D.C TO A.C INVERTER SYSTEM(2)

ABSTRACT

This project is titled the design and construction of a DC to AC inverter system. It is designed to meet up with the power demand in the offices and in homes in the absence of power supply from the national supply authority, NEPA. In order words the device / item serves as a substitute for NEPA which almost monopolises the power supply to people.

It is designed in such a way that it will take up 12v DC from battery and inverts it to an output of 220v, 50H2 AC. It makes no noise during operation and no hazardous carbon monoxide is generated in the surrounding.

This is a feature that makes it safe to use any were when compared to generator. Also, the circuit is capable of charging the battery (i.e 12v source) when the power from the supply authority is on. This greatly reduces the cost of operation of the system.
