Abstract: A passive leakage management circuit (401) for a switch leakage current includes a switch (44) having operable in a first operating mode, wherein the switch output supplies an output current having a first predetermined voltage, and a second operating mode, wherein the switch output supplies a leakage current having a second voltage, a first current path, and a leakage current path.

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.

Abstract: A passive leakage management circuit for a switch leakage current includes a switch being operable in a first operating mode, wherein the switch output supplies an output current having a first predetermined voltage. In a second operating mode, the switch output supplies a leakage current having a second voltage, a first current path, and a leakage current path.
