[Ladyada] is working on a tutorial series covering power supplies ... with the first installment which covers AC/DC converters based on a transformer like the one seen above.
The transformer isolates and steps down the AC voltage, the rectifier turns it into a rough DC, and the capacitors filter the DC to remove as much AC ripple as possible. In an audio power supply ...
A computer power supply converts AC into multiple DC voltages. For example ... For more details, see transformer. See power adapter. THIS DEFINITION IS FOR PERSONAL USE ONLY.
A power supply for electronic devices. 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 ...
