In order to illustrate my damaged memory, my age and
ignorance, but... hasn't that been the concept of many
early home computers? The external power supply would
generate (something like) 12V DC and feed that into the
computer, which would generate stabilized "sub-voltages"
(like 5V or 3 V DC) for the components on the mainboard?
If I remember correctly, computers like the ZX Spectrum,
the C64 and the Amiga 500 could be powered directly from
a battery...
