Abstract: Described herein are concepts, system and techniques which provide a means to construct robust high-field superconducting magnets using simple fabrication techniques and modular components that scale well toward commercialization. The resulting magnet assembly—which utilizes non-insulated, high temperature superconducting tapes (HTS) and provides for optimized coolant pathways—is inherently strong structurally, which enables maximum utilization of the high magnetic fields available with HTS technology. In addition, the concepts described herein provide for control of quench-induced current distributions within the tape stack and surrounding superstructure to safely dissipate quench energy, while at the same time obtaining acceptable magnet charge time. The net result is a structurally and thermally robust, high-field magnet assembly that is passively protected against quench fault conditions.

Abstract: A resistor assembly for a motor drive circuit for an electric motor assembly can have a generally circular shape. The resistor assembly includes a resistor with input and output connectors and a pair of conductor elements extending from the input and output connectors. The pair of conductor elements extend adjacent each other along a curved serpentine path so the resistor has a generally circular outer perimeter and a generally circular inner perimeter. The curved serpentine path of the pair of conductor elements allows current to flow through the pair of conductor elements so that magnetic fields generated by the current flow through the pair of conductor elements cancel each other, thereby providing the resistor with low inductance.

Abstract: Disclosed herein are passive triggering mechanisms for activation of pyrotechnic features within electrical switching devices, such as contactor devices and fuse devices.

In some embodiments, threshold strength of a magnetic field needed to trigger the passive triggering mechanism, which corresponds to a threshold level of current running through the switching devices indicating a dangerous overcurrent, can be adjusted based upon the distance between the passive triggering mechanism and a portion of the device such as a power terminal or feature connected to a power terminal.
