摘要： A closing mechanism controller includes contactor operating logic that generates a software or firmware based closing mechanism command signal. The controller also includes hardware interlock circuitry that generates an interlock signal, the hardware interlock circuity being configured to compare an interlock signal to the software based closing mechanism command signal and to provide an enable signal to the closing mechanism when the interlock signal matches the closing mechanism command signal.

摘要： A control system for an electric motor powered by a battery can be configured to receive an input power or torque command corresponding to a commanded power or torque. The control system can be configured to determine if the battery is capable of supplying and/or permitted to supply the commanded power or torque over a time period based on a state of charge (SOC) of the battery. The control system can be configured such that if the battery is capable of supplying and/or permitted to supply the commanded power or torque over the time period, the control system outputs the input power or torque command, and such that if the battery is not capable of supplying and/or not permitted to supply the commanded power or torque over the time period, the control system outputs an available maximum power or torque command corresponding to an available maximum power or torque over the time period that is less than the commanded power or torque.

摘要： A system includes a first AC bus configured to supply power from a first generator. A first generator line contactor (GLC) selectively connects the first AC bus to the first generator. A second AC bus is configured to supply power from a second generator. A second GLC selectively connecting the second AC bus to the second generator. An auxiliary generator line contactor (ALC) is connected to selectively supply power to the first and second AC buses from an auxiliary generator. A first bus tie contactor (BTC) electrically connects between the first GLC and the ALC. A second BTC electrically connects between the ALC and the second GLC. A ram air turbine (RAT) automatic deployment controller is operatively connected to automatically deploy a RAT based on the combined status of the first GLC, the second GLC, the ALC, the first BTC, and the second BTC.

摘要： A control system for an electric motor powered by a battery can be configured to receive an input instantaneous power or torque command corresponding to a commanded instantaneous power or torque. The control system can be configured to determine if the battery is capable of supplying the commanded instantaneous power or torque based on a state of charge (SOC) of the battery. The control system can be configured such that if the battery is capable of supplying the commanded instantaneous power or torque, the control system outputs the input instantaneous power or torque command, and such that if the battery is not capable of supplying the commanded instantaneous power or torque, the control system outputs an available maximum instantaneous power or torque command corresponding to an available maximum instantaneous power or torque that is less than the commanded instantaneous power or torque.

摘要： A contactor with a rotary actuation system, the contactor including a plurality of switching devices configured to switch a plurality of electrical circuits, a plurality of cam followers each operably coupled to one of the switching devices, wherein each cam follower is configured to actuate a switching device, and a cam mechanism, the cam pivotally attached to a point rotation, the cam having plurality of lobes about its perimeter, the cam in operable communication with each cam follower such that upon rotation of the cam mechanism, each cam follower engages a lobe of the plurality of lobes, it causes each cam follower to actuate the respective switching device. The contactor also includes an actuator connected to the cam, the actuator responsive to a control current and operable to rotate the cam and a controller, the controller operable to supply a control current the actuator.

摘要： A system includes a first AC bus configured to supply power from a first AC power source. A second AC bus is configured to supply power from a second AC power source. A first transformer rectifier unit (TRU) connects a first DC bus to the first AC bus through a first TRU contactor (TRUC). A second TRU connects a second DC bus to the second AC bus through a second TRUC. A ram air turbine (RAT) automatic deployment controller is operatively connected to the first TRUC and to the second TRUC to automatically deploy a RAT based on the combined status of the first TRUC and the second TRUC.
