Power supply apparatus for information appliance e.g. PC, has rectification unit rectifying AC voltage to medium voltage DC, and conversion unit transforming medium voltage DC to low voltage DC to be output
The apparatus has a power supply input unit to input an alternating current voltage. A rectification unit (2) is connected to an input end of the power supply input unit. The rectification unit rectifies the AC voltage to a medium voltage DC to be output. A portion of the medium voltage DC is output to a conversion unit, which transforms the medium voltage DC to a low voltage DC to be output.
