Abstract: Due to the erratic power supply in some parts of the World, it is imperative to source for an alternative to the municipal power supply; power generators are uneconomical and generate undesirable noise when in operation. Thus, a power inverter was designed and constructed as an operational unit to serve as an automatic supply unit in case of interruption in the main supply of power and hence reduce power failure for rural and commercial usage. The main objective of this study was to construct and evaluate the performance an electrical power inverter. It was constructed according to the rules and regulation of International Electronic Engineering Standard. Materials used for construction and evaluation of the inverter were carefully sorted and selected locally considering strength, availability, durability and cost. The main component parts include transformer, relay, capacitor, socket, alternator, multi-vibrator, resistor, integrated circuit and transistor. The efficiency was obtained by varying the load on the inverter and measuring the respective power output. The inverter has the highest efficiency of 97.40% at a load of 75W and lowest efficiency of 71.70% at a load of 600W. It was also observed that there is a decrease in the output of the machine when there is a high increase in the load. The inverter can be used for commercial purposes due to its availability in terms of material for construction, strength, its efficiency, conversion of direct current to alternating current and it can also be adopted for use in agricultural establishments.See More
