I just did a little survey to see what these power things are called in
various electronics catalogs. I have checked major parts suppliers such as
Newark Electronics, Mouser Electronics, Digi-Key Corporation, etc.

Additionally, today we also have relatively inexpensive ways to convert DC
of one voltage to DC of another voltage, and some of these methods do not
involve oscillation-transformation-rectification like the old ones always
used.

How is this done, in addition to below? (voltage up.)

Not an old timer -- you forget self contained motor generators.

In any case, these are called DC-DC converters.
