The uninterruptible power supply (UPS) is design to help in the offices, workshops and house hold appliances, due to the unstable power supply being supplied by (NEPA) presently known as Power Holding Company of Nigeria (PHCN) usually supply to us. With the help of the “UPS” we don’t need to depend much on PHCN it is stress free because it don’t need someone to change it over when light goes off, once there is any power failure it wil […]

This project is titled the design and construction of a DC to AC inverter system. It is designed to meet up with the power demand in the offices and in homes in the absence of power supply from the national supply authority, NEPA. In order words the device / item serves as a substitute for NEPA which almost monopolises the power supply to people. It is designed in such a way that it will take up 12v DC from battery and inverts it to an […]

Renewable energy sources i.e. energy generated from solar, wind, biomass, hydro power, geothermal and ocean resources are considered as a technological option for generating clean energy. But the energy generated from Renewable energy is much less than the production by fossil fuels, however, electricity generation by utilizing PV cells increased rapidly in recent years. This paper presents the Solar-UPS hybrid Power system that harnes […]

The aim of this project is to design and implement a single phase inverter which can convert DC voltage to AC voltage at high efficiency and low cost. Solar and wind powered electricity generation are being favored nowadays as the world increasingly focuses on environmental concerns. Power inverters, which convert solar-cell DC into domestic-use AC, are one of the key technologies for delivering efficient AC power. A low voltage DC sou […]

The purpose of this project is to design and construct an uninterruptible power supply. Uninterruptible power supply is a voltage regulatory and uninterruptible power device planned to electromechanically sustain a constant voltage level and supply an uninterruptible power to devices. This device receive minimum voltage of 120vac and maximum of 260vac and filter the current and voltage thereby brings out suitable voltage output to be […]
