  • Publication number: 20180145498
    Abstract: An electrical power distribution system can distribute electricity from a source to a load, and can comprise at least one solid state power controller (SSPC) having an input coupled to the source and an output coupled to the load. The SSPC can include an open shunt switch connecting the input to ground. A control circuit can couple to the shunt switch and can be configured to detect a failure in the SSPC. A fuse can be connected between the source and the input. A failure can be detected in the SSPC and the control circuit can close the shunt switch to cause a short circuit that will blow the fuse and isolate the SSPC from the source.
