You can’t readily increase a DC voltage unless you convert it into some sort of AC first. This was a particularly bad problem in the era of tubes–especially tubes in car radios. The car’s ...

you’ll probably use a DC to DC converter. Really, these converters generate some sort of AC waveform and then use either an inductor or a transformer to boost or buck the voltage as desired.

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.

They are used in power electronic applications where the power input a 50 Hz or 60 Hz sine-wave AC voltage that requires power conversion for a DC output. AC to DC converters use rectifiers to turn AC ...

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 ...
