Abstract
A method and apparatus for operating a power distribution system includes a power converter adapted to receive a power supply and convert the power supply to a power output, a set of solid state switching elements connected with the power output, a set of sensors adapted to sense a power demand at the set of solid state switching elements, and a controller module communicatively connected with the set of sensors and the set of solid state switching elements.

A method of operating a power distribution system including a power converter having a power demand threshold, comprising:
- receiving, in a controller module, a set of present power demands from a set of solid state switching elements;
- summating the set of present power demands in the controller module;
- comparing the summated set of present power demands with the power demand threshold;
- and
- when the comparison satisfies the power demand threshold, dynamically limiting a maximum current for at least a subset of solid state switching elements;
- wherein the set of solid state switching elements are connected downstream of the power converter.
A power distribution system, comprising:
- a power converter adapted to receive a power supply and convert the power supply to a power output;
- a set of solid state switching elements connected with the power output;
- a set of sensors adapted to sense a power demand at the set of solid state switching elements;
- and
- a controller module communicatively connected with the set of sensors and the set of solid state switching elements;
- wherein the controller module is adapted to obtain the set of sensed power demands, summates the set of sensed power demands, and compares the summated power demand with a maximum power demand threshold for the power converter, and when the comparison satisfies the power demand threshold, controllably limits a maximum current for at least a subset of solid state switching elements.
A method of operating a power distribution system, comprising:
- receiving, in a controller module, a set of power demands from a set of power sensors associated with a respective set of controllably switchable elements;
- comparing the set of power demands with a power demand criteria;
- and
- when the comparison satisfies the power demand criteria, controllably limiting, by the controller module, at least a subset of switchable elements such that a maximum delivered power from a power converter remains less than the power demand criteria.
