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. Continue Reading
This project work-up deals on the design and construction of a single phase step down nations fermor, with raking IKVA, 240V/11OV, 80V 12U, 6V. It is a multi-circuit transformer that has one input as the primary and tappins to produce the output (secondary). It is considered as a single coil in series with the supply and a common coil to the head. ... Continue Reading
This modern era, life without electronics is unimaginable. With the progressive increase in the number of electronic gadgets, it becomes essential to design a remote control system that can control a number of them at the same time. A remote control system now finds a large number of crucial applications like controlling of artificial satel... Continue Reading
As the world is developing the need for electronics in human endeavor is now taking a larger scope. With the invention of certain electronics gadgets in our societies today, certain activities become easily handled for example; in communication where the telephone plays a part. In places where safety are needed an alarm system will be of much impo... Continue Reading
Due to inconsistent supply of power, there is a growing need for an alternative source of power supply. This has lead to heavy capital investment in a bid to suppress power failure and ensure regular power supply for the industry, hospitals, schools and homes. The problem of power failure can be checkmated with the use of stand-by generating set. Continue Reading
This is the design and construction of an Automatic Phase Selector. In the construction work, LM324 integrated circuit (comparator) and 2N2222 transistors were used as active components alongside other passive components. The circuit components were mounted on a Vero board. Result shows that, when the three phase A.C inputs: Red phase (P1), yellow ... Continue Reading
