Generating AC from DC _does_ always involve generation of "inverted" voltages

It does not, due to unidirectionality.
But in general, diodes can be (and are) used as controlled AC switches.
One good example are the head select diodes in disk drives. You apply a
direct voltage and thus "open" the diode. You then have a overlayed

Ouch... an alternating current current and direct current current ;-)
And you usually add the voltages, not
