AC DC converter chips rectify AC input into DC output. They also adjust the voltage level through a regulator and smooth the pulsating DC through a capacitor. This video explains AC to DC conversion.

AC/DC adapters may be capable of more than one output. Many AC/DC adapters have a rating of the nominal total DC power supplied. Input plug styles, or AC pin (blade) type for AC/DC adapters can be two ...

Also called an "AC adapter" or "charger," power adapters plug into a wall outlet and convert AC to a single DC voltage. Computers use multiple DC voltages, and the power adapter is the external ...
