ABSTRACT This project presents the design and construction of a DC to AC inverter system. It is designed to meet up with the power demand in the offices/homes in the absence of power supply from National Supply Authority.  It is designed in such a way that it will take up to 12V DC from battery and inverts it to an output of 220V, 50Hz AC. It... Continue Reading

ABSTRACT 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... Continue Reading

ABSTRACT Power inverter is an electrical appliance that can be used with DC battery as an alternativesource of energy supply in the event of power failures and energy crisis. It is cheap, clean,very conducive and silent when in operation and a very reliable source of power supply as togenerator. Modern research and technologies have shown that... Continue Reading

ABSTRACT 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... Continue Reading

ABSTRACT This project review the conformability of uninterrupted power supply through the use of inverter. An inverter is a system that converts a direct current to an alternating current.  However, inverter is of different categories base on power rating such as 1KVA, 1.5KVA,2KVA, 5KVA etc. Moreover, since the invention of inverter, some...

ABSTRACT This inverter is designed to convert ac power from higher capacity dc batteries to A.C voltage (power) for systems that use ac only. It uses 24v battery D.C times 2, which is converted by the MOSFET to A.C. it is used I.C. with the model number SG3525 where the four MOSFET is connected to it. It consists winding which enable to determine... Continue Reading

Abstract Welding is a way of heating pieces of metal using electricity or a flame so that they melt and stick together. It can simply be defined as the process of joining two or more pieces of metal to make the act as a single piece. This is often done by melting the work pieces and adding a filler material to form a pool of molten material that... Continue Reading
