CONSTRUCTION OF A 12VDC TO 230VAC POWER INVERTERS

ABSTRACT

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

It is constructing in such a way that it will take up 12v DC from battery and inverts it to an output of 230v, 50Hz 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 where when compared to generator.This work is aimed at designing a modified sine wave inverter that can be used to power appliances both in homes and industries.
