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 […]

A 1.25KVA (2000W) inverter generator was designed, constructed and certified Ok. In this project, the design of the inverter generator is aimed at satisfying the need of converting, a D.C source of supply (12v battery) to an A.C voltage of 220v. The inverter range of output is between 200-220v. Since the inverter was designed to step-up voltage, the power transformer is being used as step-down transformer for charging and as step-up tr […]

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 machine is designed to serve with an output of 250A. it has two pats which are the primary and secondary parts. The primary part, through which voltage is supplied to the machine has 180 turns which is made of 2mm2 S.W.G 14 copper coil. The secondary part has 45 turns made of 4mm2 S.W.G 8 copper coil. Both turns are wound on separate limb of the laminated core. The voltage from primary turns flows to the secondary turn by induction […]

This project entails the design and construction of a pure sine wave inverter system, which generates a pure sine wave output identical to the mains supply. Unlike modified sine wave inverters, pure sine wave inverters produce a high-quality output that ensures proper functioning of high-end electronic equipment and smooth operation of appliances with reduced heat and noise. The pure sine wave inverter takes in 12V DC from a battery an […]
