摘要： A power line communication-based aircraft power distribution system may allow for both power line communication (PLC) technology and spread spectrum time domain reflectometry (SSTDR) technology to be utilized in aircraft power distribution systems to achieve key maintenance functions. Unlike conventional power distribution systems, which may, for example, use only SSTDR for fault detection, the present invention includes a hardware platform that may allow both the PLC and the SSTDR to be utilized in aircraft power distribution systems to achieve key maintenance functions, such as real time wire fault location, and cost and weight savings. Further, unlike conventional power distribution systems, which may only detect and locate damage in feeder conductor wire sections before the power is applied to the load, the power distribution system of the present invention may permit real time wire fault location.

摘要： Redundant functionality is implemented in a control of solid state power switching controller (SSPC) (1) to ensure that each power switching channel operates according to a default configuration in case of failure. Each power switching channel in the SSPC includes a solid state switching device (SSSD) (120) that is controlled by a supervisory controller (10) to perform power switching functions for a corresponding load. The SSPC further includes a nonvolatile memory device (44) that stores default commands for controlling the SSSDs in case the SSPC enters into a backup mode, e.g., due to a failure in the supervisory controller. The nonvolatile memory device may be assembled on the same SSPC circuit board as the power switching channels, thereby ensuring that backup control is performed locally in the SSPC device.
