Power Supplies

Definition

A power supply is an electrical device that supplies electric power to an electrical load.

The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load.

As a result, power supplies are sometimes referred to as electric power converters.
