Abstract: A solid state power controller for delivering power to a load is provided. The solid state power controller includes a set of sections, where each section includes at least one power switching block. The solid state power controller further includes protection circuitry in each section. The protection circuitry is configured to prevent a fault occurring in one power switching block to propagate to the other sections, to other power switching blocks, or to the load.

Abstract: An electrical power distribution system is provided. The electrical power distribution system includes one or more power distribution cards comprising a first portion and a second portion. The electrical power distribution system further includes one or more power switching components coupled to the first portion of one of the one or more power distribution cards. The electrical power distribution system further includes one or more control devices configured to control operation of at least one of the one or more power switching components. Each control device is coupled to the second portion of one of the one or more power distribution cards. The first portion of each power distribution card is separated from the second portion, such that, during operation of the power distribution card, the control devices operate at a lower average temperature than the power switching components.

Abstract: Method(s) for limiting current in an electrical circuit having transmission wires for power transmission include determining whether an unexpected operating condition exists along the transmission wires and limiting the current to prevent (damage caused by) the unexpected operating condition. The method may further include disabling the electrical circuit if the unexpected operating condition persists. Additionally, a system includes a power source, a solid state power controller (SSPC) configured to operate in a first conducting state and a second non-conducing state, and a controller.
