DESIGN AND CONSTRUCTION OF 100W ELECTRIC POWER INVERTER

ABSTRACT

No one form of power can sustain a nation. The ever increasing demand for electrical power has arisen from our lifestyles with revolves around electric power to speed up processes of development such as manufacturing, service provision and general well being of man.

The need for the provision of quick but minute energy to prevent the disruption of small but very important business or personal processes could be life saving promoting efficiency at all times.

This project work goes through the design, local manufacture of a 100w inverter a light weight device used to solve very meager power problems yet so vital.
