    摘要: The invention provides an apparatus for shunting leakage current of a solid state switching device (SSSD) (10). The apparatus selectively provides a shunt pathway to divert current away from the output load based on the switching state of the SSSD. The apparatus may include a shunt impedance component (14) connected to the SSSD, and a switching element (16) for selectively connecting the other end of the shunt impedance component to ground based on the switching state of the SSSD. Accordingly, when the SSSD is turned off, the switching element is switched to a state that connects the shunt impedance component to ground, thereby shunting leakage current.

    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: An AC/DC power converter has, as its first stage, a capacitor divider and rectifier and, as the second stage, a switch mode power supply. This configuration may be suitable for low power low voltage aerospace applications. The benefits of the circuit may include small reactive component size; near sinusoidal input current, low EMI emissions resulting from low inrush current; intrinsic current limiting that may eliminate the need for short circuit protection; and low overall component count.

    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: An electrical power distribution system comprises a solid state power controller in communication with an aircraft system main data bus via a gateway module and a condition based maintenance module in communication with the solid state power controller via a communication network distinct from the main data bus. A method of load/feeder health assessment for an electrical power distribution system includes applying a controlled excitation to a load; sampling information from the load/feeder system for the load; characterizing a normal behavior of the load/feeder system for the load; determining if the load characteristics are within the normal behavior profile for the load; and shutting down power to the load if load characteristics are not within the profile when immediate action is indicated or generating a health message for the load when immediate action is not required.

    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.
