摘要： On an aircraft, primary power distribution control and secondary power distribution control may be performed with a single line replaceable module (LRM) having an integrated architecture. The LRM may be provided with trip engines that are based on digital signal processors (DSP's). The DSP's may be programmed to allow the trip engines to perform either ELCU functions or SSPC functions. Use of the single LRM precludes a need for complex circuitry that might otherwise be required to coordinate prior-art independent ELCU and SSPC controls.

摘要： The present invention provides an overload protection circuit having a first switch connected at a first side to a source of electrical power and at a second side to a load, the switch having on and off modes and a second switch connected between the first switch second side and ground, the second switch having on and off modes. A control module generates at least one signal controlling the first switch mode and the second switch mode wherein the signal turns the second switch to the off mode when turning the first switch to the on mode and the signal turning the second switch to an on mode when turning the first switch to the off mode. Both over current and leakage protection are thereby achieved.

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.

摘要： A system and method for control of an electric power distribution system is provided, which uses a communication network for centralized monitoring and control of the supply of electricity to a load. In one embodiment, the invention may use a wireless communication system connecting control nodes and master nodes to control and monitor a solid state power controller. As a result, the master node may remotely turn on and off the electrical power to the load. Also the control node may sense the current being supplied to the load and may turn off the supply of electrical power in the event of an over current situation. The control node may also report the state of the sensed current to the master node. In another embodiment, the communication system may be a power line carrier network.

摘要： A ground fault interruption (GFI) system is incorporated onto a DSP based LRM of an aerospace vehicle. The GFI system operates with digital controls and, unlike the prior art, the system does not employ current transformers. Synchronization pulses are employed to coordinate instantaneous current measurement samplings in each phase of a multi-phase power system. Coordinated sampling may reduce phase angle current differential errors and improve operational precision of the GFI system.
