Solid-State Power Controller Channel Protection Systems and Methods

摘要

A scalable solid-state power controller system is provided with channel protection features. A plurality of output channels may be combined to provide a combined channel output. The current provided at the combined channel output is sourced from the plurality of output channels and each channel is protected from faults such as overcurrent events.

1. A scalable solid-state power controller system comprising:
a power source comprising a channel bank comprising a plurality of output channels comprising a first output channel and a second output channel; a first solid-state power controller comprising a first channel current switching circuit; a second solid-state power controller comprising a second channel current switching circuit; a controller in electrical communication with the first solid-state power controller and the second solid-state power controller; and a combined channel output, wherein the first channel current switching circuit is disposed in series between the combined channel output and the first output channel, wherein the second channel current switching circuit is disposed in series between the combined channel output and the second output channel, wherein the first channel current switching circuit controls a first current supplied by the first output channel in response to the controller, and wherein the second channel current switching circuit controls a second current supplied by the second output channel in response to the controller.
