    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.
