Backup control for solid state power controller (SSPC)

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 (SSS...

Zusammenfassung:	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.
