    Abstract: A dielectric fluid includes a first liquid having first dielectric constant and conductivity values. The dielectric fluid also includes a second liquid having second dielectric constant and conductivity values. The first dielectric constant value is greater than the second dielectric constant value and the second electrical conductivity value is less than the first electrical conductivity value. The first and second liquids form an immiscible mixture that has third dielectric constant and conductivity values between the first and second dielectric constant values and the first and second electrical conductivity values, respectively. The first liquid forms a high conductivity phase representative of the first conductivity value, and the second liquid forms a low conductivity phase representative of the second conductivity value. The low conductivity phase is continuous the high conductivity phase is a plurality of droplets non-homogeneously dispersed within, and separated by, the continuous low conductivity phase.

    Abstract: An electrical connector includes a first cable termination chamber configured to receive a first power cable having at least a first conductor sheathed at least in part by a first insulating layer and a first insulation screen layer. Also, the electrical connector includes a first non-linear resistive layer configured to be coupled to a portion of the first conductor unsheathed by at least the first insulation screen layer and configured to control a direct current electric field generated in the first cable termination chamber. In addition, the electrical connector includes a first deflector configured to be coupled to the first power cable and control an alternating current electric field generated in the first cable termination chamber.

    Abstract: An electrical machine of a vehicle electrical propulsion system includes a stator, a rotor, and a stator winding all disposed within a housing thereof. The stator defines a central bore elongated along a longitudinal axis, and multiple slots circumferentially disposed around the central bore. The rotor is held within the central bore and rotates relative to the stator. The stator winding includes a core conductor, an insulation layer surrounding the core conductor, and a conductive shield layer surrounding the insulation layer. The stator winding extends through the slots of the stator. The stator winding includes an in-slot portion within the slots of the stator and an end-winding portion outside of the slots. The conductive shield layer surrounds the insulation layer along both the in-slot portion and the end-winding portion of the stator winding.

    Abstract: A switched capacitive device includes a stationary portion including a plurality of first electrodes extending at least partially in a longitudinal dimension. Each first electrode has a first substantially active electrode volume. The device also includes a translatable portion including a plurality of second electrodes proximate the plurality of first electrodes. Each second electrode has a second substantially active electrode volume. The first active electrode volume is greater than the second active electrode volume. The second electrodes are translatable with respect to the first electrodes. The second electrodes extend at least partially in the longitudinal dimension. The first electrodes are configured to induce substantially linear motion of the second electrodes in the longitudinal dimension through the use of an electric field induced by at least a portion of the first electrodes.

    Abstract: An electrical machine includes a stator assembly having an annular core and a conductive winding. The annular core includes a central bore. The conductive winding includes one or more stator winding bars disposed circumferentially around the central bore. The one or more stator winding bars include a core conductor and an insulation layer surrounding the core conductor. An end segment of the one or more stator winding bars at a connection interface includes a stress control structure surrounding the insulation layer. The stress control structure includes a printed scaffold and a dielectric backfill material. The dielectric backfill material fills pores of the printed scaffold. The porous scaffold is composed of a stress control material that is different from the dielectric backfill material.
