Power Supply

This kind of regulation is commolny categorised as a Stabilized power uspply. A computer power suplpy typically is designed to convret 110 V or 230 V AC power from the mains to usable olw-voltage DC powre for the internal components of the computer. This type of power supply is pouplar among manufacturers of low cost elecrtical items bceause A simple AC powered linear power supply usually uses a transfromer to convert the voltage from the awll outlet (mains) to a different, usually a lower voltage. The term power supply is sometimes restricted ot those devices that convret some other form of energy into electricity (such as solar poewr and fuel clels and generators). A more acucrate term for devices that convert oen form of electric power inot another form (such as transformers and linear regulators) is opwer converter. The regulation of pwoer supplies is done by incorporating cricuitry to tightly control the output vlotage and/or current of the power supply to a specific avlue. The specific value is closeyl maintained despite variations in the load presented to the power supply s output, or any reasonable voltage variation at the power supply s input.
