  • Patent number: 11932181
    Abstract: An electronic component includes external ground connections for connecting to a cable harness and internal ground connections electrically coupled to paired external ground connections so that the potential at each internal ground connection corresponds to the potential at the paired external ground connection. An analysis circuit determines on which internal ground connections first and second signal information is applied to infer a coding of the component from the pattern of the internal ground connections being supplied with the first and second potential. A combination circuit connects the internal ground connections to the external ground connections such that when a ground line of a cable harness is connected to precisely one of the external ground connections, the first signal information is applied to a respective different sub-quantity of internal ground connections depending on which of the external ground connections the ground line is connected to.

  • Patent number: 11894781
    Abstract: A housing and/or installation frameworks for a modular multi-level energy system includes a set of similar cabinets configured for orthogonal (e.g., vertical and horizontal) alignment of the modules. The cabinets are configured so modules of a particular phase are oriented along an axis parallel to a reference plane. Modules of the same level of the multi-level arrangement but of different phases are mounted in each cabinet, arranged such that a module for each phase is a defined distance from the reference plane. The cabinets are arranged equidistant and orthogonal to the reference plane, minimizing distance for connections between modules of the same phase across multiple cabinets, and facilitating convenient addition or removal of levels. The framework also facilitates data and reference signal connections between local control devices of the modules, and between the local control devices and a master control device for the system.

  • Patent number: 11878594
    Abstract: Methods and apparatus for detecting and characterizing arc faults in an aerospace electric propulsion system and then coordinating the operation of various elements of the protection system to execute a fault-clearing sequence. In a current-based method, the arc is detected and characterized based on differential readouts from current sensors. The difference between currents measured at two ends of a protection zone are compared to a difference threshold. In a power-based method, the arc is detected and characterized based on differential readouts from voltage and current sensors. The differential voltage and current readouts are used to compute the respective powers at two ends of a protection zone. The difference between the respective powers is integrated over a period of time and then the integrated difference is compared to a difference threshold. A differential protection trip mode is invoked when the difference threshold is exceeded.
