1. A system, comprising:
a first DC-to-DC converter, connected between a first node and a second node, and configured to maintain a first voltage level at the second node;
a second DC-to-DC converter, connected between the first node and the second node; and
a controller configured to:
measure a current through the first DC-to-DC converter;
cause, in response to a measure of the current being in a specific relationship with respect to a first threshold current, a change in electric power being conveyed through the second DC-to-DC converter to cause the second DC-to-DC converter to respond to a first subsequent change in electric power being conveyed through the second node, the first subsequent change in electric power being one of an increase or a decrease; and
cause, in response to the second DC-to-DC converter having been caused to respond to the first subsequent change in electric power being conveyed through the second node:
an output electric power of the first DC-to-DC converter to change in a manner that is different from the first subsequent change in electric power; and
an output electric power of the second DC-to-DC converter to change according to the first subsequent change in electric power.
