interleaved boost
other advantages would be the reduced output current ripple (so bulk capacitor size can also be reduced).
the magnetics are also "distributed" so it's easy to manage the temperatures..
it increases the efficiency not only in full load, but also in light load (to do this, it's need to disable the other rail(s) during partial load.)
interleaving requires smaller EMI filters.
(the reduce input ripple current also minized or elimated the use of differential mode EMI filter.)
