    Abstract: An integrated power quality control system includes a transformer with a primary winding, a secondary winding and a compensation winding wound on a magnetic core. A power electronic converter in the system provides a reference voltage to the compensation winding for injecting a series voltage in the secondary winding of the transformer. A controller is utilized to generate the reference voltage for the power electronic converter based on a power quality control requirement.

    Abstract: A core includes a first layer, a second layer, and a third layer. The first layer has a first surface, a second surface, and a first recessed pattern extending from the second surface of the first layer toward the first surface of the first layer. The second layer has a third surface, a fourth surface, a second recessed pattern extending from the third surface of the second layer toward the fourth surface of the second layer, and a third recessed pattern extending from the fourth surface of the second layer toward the third surface of the second layer. The third layer has a fifth surface, a sixth surface, and a fourth recessed pattern extending from the fifth surface of the third layer toward the sixth surface of the third layer. The second layer is disposed between the first and third layers such that the second surface of the first layer faces the third surface of the second layer and the fourth surface of the second layer faces the fifth surface of the third layer. The first and second recessed patterns correspond to one another and are configured to receive a coil. The first, second, and third layers have non-uniform magnetic permeabilities.

    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.
