Power supplies convert AC input to DC output.

Detailed explanation-1: -Transformer. This component changes (increases or decreases) the voltage of the incoming power to the necessary voltage level for the connected device. Rectifier. In AC-DC power supplies, this component converts the AC current of the incoming power to the DC format.
Detailed explanation-2: -By definition, a power supply is a device that converts the output from an ac power line to a steady dc output or multiple outputs. The ac voltage is first rectified to provide a pulsating dc and then filtered to produce a smooth voltage.
Detailed explanation-3: -A power supply takes the AC from the wall outlet, converts it to unregulated DC, and reduces the voltage using an input power transformer, typically stepping it down to the voltage required by the load. For safety reasons, the transformer also separates the output power supply from the mains input.
