I'm interested how is solved the weight problem for such supplies.
I guess one of the schematic choice is based on one or more switching
supplies connected in parallel followed by a low drop linear
regulator. Both the switching and the regulator should be
synchronised.
Probably using ferrite core and high frequency for switching is the
way for decreasing the weight.
I can't imagine 50/60Hz toroidal transformers in those supplies, or I wrong
?

thx,
Vasile
