DESIGN AND CONSTRUCTION OF 5KVA SINE WAVE INVERTER

It is a statement of fact that power plays a significant role in our daily life. However, Nigeria as a developing country has a lot of challenge in the area of electric power supply. The challenges include inadequate of electric power generating which causes instability of electric power supply in Nigeria. This problem is the course of low productivity in Nigeria, which highly affects our economy. In the above challenges, several efforts have been made to over come this challenge of power instability of electricity, but present outcome are difficult or rejected for its high disadvantages, which as generating set heavy duty diesel engine, solar panel, etc when this alterative source of energy for electric power supply are presented, it create another challenges such as fueling, replacement of parts and producing pollution all over the area. The inverter system is one substituted for these lapses seen in the above mentioned alternative sources. The inverter system is an electronic system that converts stored chemical energy in battery into electrical energy. Therefore, an inverter system is an electronics circuit that convert Direct  Current (DC) to Alternating Current (AC). The capacity of an inverter depends on the application of the appliances and the area by which appliances are to be used. For the purpose of being clearly, the inverter as we are discussing it here may have another scope, but is purely designed for domestic use with its maximum capacity of 5KVA is about 4000watts. It serves as UPS for where there is power failure and also serve as a generating source where there is no power supply form the national grid.
