Power Source and Requirement

Power sources or power supplies are electronic circuits composed of different electronic components, that convert an alternating current (AC) into direct current (DC). Power supply devices are commonly known as AC-DC or AC to DC converters. Power sources are often known as power supply units (PSU) and are used almost in every electronic device that uses a DC power supply. Armature radio transmitters, receivers, and uninterruptible power supply (UPS) are some examples of power supply units. The requirement of UPS is as a crucial power supply unit for computers, which prevents data from getting corrupted in case of sudden power failure, it also prevents various components used in the computer motherboard from getting damaged. The similarity between these units is that all of them use AC as the main power source, which requires the power chord to plug into the wall power socket.
