Design and Construction of a 0.75KVA Inverter Power Supply for Nigerian Homes and Offices

Over the years, there have been a gradual increase in the electricity generation capacity of Nigeria, with more gas power plants installed between 1999 2003 to augment power supply from the existing hydro and thermal power plants installed in the 1970s but despite gradual increase in Mega Watts MW of electric power generated, Nigerian electricity consumers continue to experience epileptic and unreliable power supply distribution. As at today, the power distribution companies referred to as the DISCOs supply epileptic or skeletal power to their customers which they termed 'load shading'. This term explains a situation whereby a power consumer or customer can obtain a power ration for some hours in the day and do not have power remaining hours in the day. Because of this, many consumers depend on generating sets as alternative source of power. This is inefficient and costly to maintain. Today it is possible to introduce the electric power inverter which converts battery DC voltage to AC voltage. Inside the inverter can be coupled an electric charging system which can charge the battery when there is power supply from utility power source. When this power source fails, the battery in turn supplies the inverter with DC which is being converted to A.C sometimes the inverter can also be connected to renewable energy source like solar, wind etc. These sources ensures an all round supply of DC for the inverter. Renewable energy can be particularly suitable for developing countries such as Nigeria where public power supply is totally unreliable. In response to the yearning of the majority of Nigerians for a steady power supply, this research paper tries to contribute in a little way by designing and constructing a 0.75KVA inverter to power homes and offices. The paper starts by defining what an inverter is, reviewed similar past works in literature, and it explained the principles of operation and components used with its circuit diagram. The completed work was tested and met its design specifications. Lois O. Nwobodo | Nkemdilim Ifeyinwa Obiokafor | Samuel C. Asogwa | Fidelis C.
