Abstract: In accordance with at least one aspect of this disclosure, a failure detection system for an integrated circuit component includes an integrated circuit component configured to connect to a circuit board, a first sensor operatively connected to sense and output a signal indicative of an actual current output of the component in a first state, and a second sensor operatively connected to sense and output a signal indicative of an actual condition of the component in the first state. A logic module can be configured to output a component failed state signal based at least in part on the signal indicative of the actual current output of the component in the first state and the signal indicative of the actual condition of the component in the first state.

Abstract: A thermal management includes an inductor, a housing in thermal communication with the inductor, the housing defining a wall, and a conductor. The conductor has a greater heat transfer rate than the wall and is positioned within a groove and/or an aperture formed in the wall. The conductor is configured to transfer heat through the wall more efficiently than if the conductor were not present. A method of manufacturing a thermal management system includes forming a housing by additive manufacturing. The housing defines a wall having at least one of a groove and an aperture defined therein. The method includes positioning a conductor in at least one of the groove and the aperture. The conductor has a greater heat transfer rate than the wall. The method includes positioning an inductor into thermal communication with the housing.

Abstract: A wedge for a wound rotor includes a wedge body. The wedge body has a first layer and one or more second layers interfused with one another to provide structural support and limit resistive heating of the wedge from current flow within the wedge body by windings spaced apart by the rotor wedge. Generator rotors and methods of making generator rotors are also described.

Abstract: A transformer assembly includes a housing, a core within an interior of the housing, and at least one winding positioned around the core. The at least one winding and the core are mounted to the housing with potting material. At least a portion of a fluid circuit is defined within at least one wall of the housing. The at least the portion of the fluid circuit is defined through an opening in the at least one wall of the housing in fluid communication with the interior of the housing. A transformer assembly includes a housing, a core within an interior of the housing, at least one winding positioned around the core, and a fluid circuit defined at least partially within at least one wall of the housing being configured such that heat is transferred to the fluid from at least one of the core and the at least one winding.
