1.1 BACKGROUND OF THE STUDY
Power supply is an electronic device that supplies electric energy to an electrical
load. The primary function of a power supply is to convert one form of electrical
energy to another and, as a result, power supplies are sometimes referred to as
electric power converters. Some power supplies are discrete, stand-alone devices,
whereas others are built into larger devices along with their loads. Examples of
the latter include power supplies found in desktop computers and consumer
electronics devices.
