A transformer includes: a magnetic core including a lower magnetic structure and an upper magnetic structure; a printed circuit board arranged between the lower magnetic structure and the upper magnetic structure and including a core hole through which a midsection of the magnetic core penetrates, a primary coil, a secondary coil, a primary via-hole formed at an end of the printed circuit board and electrically connected to the primary coil, and a secondary via-hole formed at another end of the printed circuit board and electrically connected to the secondary coil; a primary pin inserted into the primary via-hole; a secondary pin inserted into the secondary via-hole; an insulating block into which a portion of the printed circuit board is inserted; and a mount on which the printed circuit board and the insulating block are mounted.

A dry-type transformer, comprises a magnetic core, at least one high voltage (HV) winding, and at least one low voltage (LV) winding inductively coupled to the magnetic core. The transformer is made by determining a shape of an electric field that is generated, 3D printing a dielectric structure shaped to conform to the determined shape of the electric field, and mounting the dielectric structure between the HV and LV windings. A dielectric barrier arrangement for electrically isolating a coil of a transformer assembly from a further coil of the transformer assembly or from a core of the transformer assembly comprises a first dielectric structure having a first cylindrical dielectric structure extending along a longitudinal axis (L).

Methods and systems are provided for a multi-stage solenoid actuator. In one example, a system may include a solenoid actuator comprising a series of coils, the first coil enclosed by a first housing, the second and third coils enclosed by a second housing, and a plunger enclosed by the second housing. The method may include the first and second housing, and the plunger, moving in series, increasing the total displace of the actuator via single electric signal.

A magnetically tunable ferrimagnetic filter, including a top casing, a top magnetic conductor, a bottom magnetic conductor, coils, a balance coil, ferrimagnetic-based filters, and a bottom casing. The ferrimagnetic-based filters utilize ferrimagnetic resonator elements, such as yttrium-iron-garnet (YIG), configured to reduce a magnetic gap of the YIG filter and thereby to improve performance.

A tank assembly has heat-generating equipment contained therein. The tank assembly includes a tank having an opening, and a thermal siphon fixed to the tank and sealing the opening of the tank. The thermal siphon has a main body portion and a loop portion. The thermal siphon contains a liquid and a gas. A center of the loop portion is exposed to the environment.

A transformer includes two first cores, a primary winding and a secondary winding. The secondary winding has a first section and a second section. The first section has a first outlet end, a second outlet end, and a first connection end, wherein the first outlet end and the second outlet end are located at a side of the first section, the first connection end is located at an opposite side of the first section. The second section has a third outlet end, a fourth outlet end, and a second connection end. The third outlet end and the fourth outlet end are located at a side of the second section, and the second connection end is located at an opposite side of the second section. A portion of the primary winding is located between the first section and the second section of the secondary winding.

A magnetic part including: a coil that generates a magnetic flux when a current flows through the coil; a core that is formed of a magnetic substance that forms a magnetic path of the magnetic flux; a support member that supports the core; and a fixing member that fixes the core to the support member. The core includes a column portion that is vertically provided with respect to a surface where the core is in contact with the support member. The fixing member presses the column portion of the core against the support member. The support member has a recess in a portion of a facing surface that faces the core, where the portion of a facing surface does not face the column portion.
