The availability and stability of electrical energy is necessary for domestic and industrial use. But unfortunately the monopoly which the Power holding company of Nigeria (PHCN) enjoys in this country is not in favor of the electricity users, because the supply is never constant and damages occur due to inconsistency of this supply is very enormous. However, millions of naira’s are lost every day in the commercial and industrial sectors, and even at the same time a lot of Lives are wasted in hospital, theaters and emergency wards. All these should give causes to an alternative to electricity supply.
Conventionally, there are two ways in which electrical power is transmitted. Direct current (DC) comes from a source of constant voltage and is suited to short-range or device level transmission. Alternating current (AC) power consists of a sinusoidal voltage source in which a continuously changing voltage (and current) can be used to employ magnetic components. Long distance electrical transmission favors AC power, since the voltage can be boosted easily with the use of transformers. By boosting the voltage, less current is needed to deliver a given amount of power to a load, reducing the resistive loss through conductors.SQUARE WAVE TO SINOUNSIDAL WAVE FORM
