I have a vague understanding of what it is but why is it called a
"Galvanic" isolator? What I am looking at is a bunch of DC/DC converters
for an industrial control system and they have them labeled as "Galvanic
Isolators". Why not just call them DC/DC power supplies? Are they more
than just a DC/DC converter? The circuit is a simple oscillator made
from discrete components that fires a 1:1 pulse transformer and the
output is just rectified and unregulated. Nothing fancy about it.

Merry Christmas to all.
