Abstract: A system for acoustically detecting dielectric breakdown of, or partial discharge within, or on, an electrical device includes at least one electroacoustic (EA) transducer configured to detect an acoustic vibration of the electrical device, and a controller electrically connected to the at least one EA transducer. The controller is configured to receive a signal from the at least one EA transducer, and analyze the signal to determine whether the signal includes data associated with an acoustic vibration in a frequency range of dielectric breakdown and/or partial discharge of the electrical device. The applicability of such a system includes, but is not limited to, electronic parts or assembly screening, life characterization testing for materials and processes, diagnostic methods or aides, augmenting testing of components, assemblies or systems, and in service monitoring to support preventative or condition based maintenance to avert an in-service issues.

Abstract: An apparatus for magnetic field compression includes a plurality of tubes of different dimensions. Each smaller tube extends within a larger tube and each tube includes an electrically conductive material for generating a magnetic field in response to electric current flowing in the conductive material. A longitudinal slot is formed in each tube. The longitudinal slot in each tube is aligned to form an aperture in which the magnetic field is compressed or has a highest magnetic flux in the aperture in response to the electric current flowing in the conductive material of each tube.

Abstract: A system for generating an energy beam based laser includes an apparatus for receiving an energy beam and for generating an energy beam based laser. The apparatus is configurable or controllable for tuning an output wavelength of the laser generated by the apparatus using the energy beam. The apparatus includes a first component for producing a first magnetic field oriented in a first direction and a second component for producing a second magnetic field oriented in a second direction substantially opposite to the first direction. A channel through the apparatus is defined by the first component and the second component through which the energy beam passes to generate the laser at an output of the apparatus. The apparatus is configurable or controllable for modifying at least one of the first magnetic field and the second magnetic field for tuning the output wavelength of the laser.

Abstract: An apparatus for magnetic field compression includes a toroid and a plurality of separate coils wound around the toroid. The coils are spaced about a circumference of the toroid and each coil generates a magnetic field in response to electric current flowing in the coil. The toroid and a group of the coils each include a size that respectively gradually decreases over a predetermined portion of the toroid. The magnetic field is compressed or has a highest magnetic flux density proximate a central region of the coils around the toroid.

Abstract: A smart susceptor assembly including an electromagnetic flux source such as one or more inductors, a geometrically complex-shaped susceptor having one or more contours, and a cladding on or over the susceptor. The cladding can alter both the thermal performance and the electrical operation of the smart susceptor assembly. With regard to thermal performance, the cladding can function as a passive heat exchanger to dissipate thermal energy across the surface of the susceptor. With regard to electrical operation, the cladding can provide a current path after portions of the susceptor heat and become low or non-magnetic.

Abstract: A honeycomb thermal insulation structure may comprise a first facesheet, a second facesheet, and a honeycomb core between the first facesheet and the second facesheet. The honeycomb core may include a plurality of honeycomb unit cells each composed of walls having a height and spaced by a distance. The walls of the honeycomb cells may have perforations. The honeycomb thermal insulation structure may further comprise a non-convective gas loaded in the honeycomb unit cells between the walls. A flow of the gas through the perforations may be substantially absent.

Abstract: A method includes a first electrode exhibiting a first Seebeck coefficient, a second electrode exhibiting a second Seebeck coefficient greater than the first Seebeck coefficient, and particles between the first and second electrodes exhibiting a third Seebeck coefficient between the first and second Seebeck coefficients. Heat is generated due to the Peltier effect at a junction between the first electrode and the particles and at a junction between the second electrode and the particles. Heat is removed due to the Peltier effect at the junction between the first electrode and the particles and at the junction between the second electrode and the particles. The particles are densified due to heating and cooling phase transitions between a higher-temperature solid phase and a lower-temperature solid phase while compressing the particles. An apparatus includes the first and second electrodes and an alternating current power supply electrically connected to the first and second electrodes.

Abstract: Provided is a cooling device, and methods of fabricating and operating such cooling devices, for electromagnetic induction (EMI) filters. Specifically, a cooling device is provided which comprises a housing enclosing the electromagnetic induction filter. The housing may comprise one or more of the following: one or more exterior chambers, one or more central flow channels, and peripheral flow channels. The one or more exterior chambers surround an exterior surface of the EMI filter. The one or more central flow channels extend the length of the center of the EMI filter. The peripheral flow channels extend the length of the exterior of the electromagnetic induction filter. The peripheral flow channels may be disposed between one or more exterior chambers and open into the one or more exterior chambers. The one or more central flow channels, the peripheral flow channels, and the one or more exterior chambers are interconnected.

Abstract: Provided is a low-weight, high-efficiency inductor design for use with or in electrical power equipment, such as inverters. A toroidal power inductor includes a support structure comprising an outer shell, an inner shell, and one or more coolant channels formed therebetween, a plurality of conductors wrapped around and supported by an exterior surface of the outer shell, and an interior cavity substantially enclosed by the inner shell of the toroidal support structure. The plurality of conductors are configured to provide an inductance for the toroidal power inductor, and the one or more coolant channels are distributed beneath the exterior surface of the outer shell to cool the plurality of conductors. An air-core power inductor may implement the conductors using high-temperature superconducting (HTS) tapes cooled by cryogenic fluid flowing within the coolant channels.
