A system that converts AC current from the wall outlet into the DC currents required by electronic circuits. A computer power supply converts AC into multiple DC voltages. For example, 12 volts is ...

and the capacitors filter the DC to remove as much AC ripple as possible. In an audio power supply the capacitors have the dual role of filtering and providing an impulse reservoir for the supply ...

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 ...

The PC power supply has been a standard of the junk box ... a pair of high-voltage power transistors that switch the resulting DC at a few tens of kHz into a ferrite-cored transformer whose ...
