摘要： A wireless, parasitically powered data processing unit 1 is fastened to a current carrying conductor 3 without additional tools, by means of a flexible ferromagnetic belt 11 that is clamped by its housing around the conductor and forms a transformer core to concentrate magnetic flux 5 produced by the conductor and provide operational power to a sensor interface 18, a data processing device 16, and a wireless transceiver 22, without the need for batteries. Sensor signals 33 received from local sensors are processed by the data processing device and information derived from the sensor signals is wirelessly transmitted to remote receivers. The sensor signals may represent measurements of the physical condition of the current carrying conductor or another electrical device, for such conditions as temperature, humidity, vibration, or noise.

摘要： The inductor comprises a winding arranged around a core formed by at least two rigid magnetic elements connected in an articulated manner forming an oblong assembly, each comprising: a head end A provided with a circular convex curved surface and a tail end B provided with a circular concave curved configuration, in relation to a transverse axis of the tail, parallel to the transverse axis of the head, and the configuration being complementary to said circular convex curved configuration. The head end A is coupled to the tail end B forming an articulated attachment, and the transverse axes of the head and tail coincide in the coupling area, providing a joint having a variable, adjustable angle, wherein the assembly of said two or more rigid magnetic cores is surrounded by a flexible polymer casing, including magnetic charges that work together to prevent magnetic flux dispersion in the coupling gaps or interstices between the magnetic cores.

摘要： An object of the present invention is to improve a mechanical strength and to ensure a low magnetic loss without using a supporting member even when amorphous ribbons are used for an inner core. To attain the object, a stationary induction apparatus core of the present invention includes an inner core formed from the amorphous ribbons and outer cores formed from silicon steel sheets, the outer cores being disposed on two sides of the inner core in a depth direction as opposed to a standing direction of the inner core in such a manner as to sandwich the inner core therebetween.

摘要： An electronic filter assembly includes a magnetically conductive annular body extending around a center axis, a set of magnetically conductive prongs radially extending from the center axis toward the annular body, and conductive windings extending around the prongs. The conductive windings can be disposed around the prongs instead of the annular body to assist in conduction of common mode magnetic flux, to reduce impedance of the filter assembly, and/or to more evenly distribute temperature in the filter assembly. A method for forming an electronic filter assembly includes forming an electronic filter assembly having a magnetically conductive annular body extending around a center axis and a set of magnetically conductive prongs radially extending from the center axis toward the annular body. The annular body and the prongs can be formed by coupling plural layers of magnetically conductive bodies together.

摘要： A resonant high current density transformer with an improved structure includes a secondary insulating bobbin, a primary insulating bobbin and a core assembly. The secondary insulating bobbin includes a base. Two posts extend from a first side of the base, and a raised plate extends from a second side of the base, the second side is opposite to the first side. The two posts and the raised plate form a receiving space for receiving an insulating sheath having a plurality of sleeves. A secondary winding is provided on each of the sleeve. The primary insulating bobbin having a tunnel is provided at one side of the secondary insulating bobbin. The surface of the primary insulating bobbin is provided with a primary winding and covered by an insulating cover. A core assembly includes a first core and a second core. A first primary core column and a second primary core column opposite to each other extend from a side of the first and second cores, respectively, and a plurality of first secondary core columns and a plurality of second secondary core columns extend from another side of the first and second cores, respectively. The first primary core column and the second primary core column are inserted into the tunnel of the primary insulating bobbin, while each of the first secondary core columns and each of the second secondary core columns are inserted into a corresponding one of the sleeves. As a result, the secondary windings are capable of withstanding large current. Their overall length covers the air gap of the core assembly, thus achieving magnetic shielding. Meanwhile, production and assembly processes are simplified.

摘要： A coil former, also referred to herein as a bobbin, is provided for use in conduction-cooled magnetic components that contain an air gap. The diameter of the disclosed bobbin is increased and ribs/splines or tabs are created to keep the winding centered about the core center post while allowing thermally conductive silicone-based or equivalent encapsulant to fill the voids between the coil former and the core, the coil former and the windings and/or both depending on the placement of the locating tabs. The disclosed bobbin may be fabricated from traditional injection molding resins or from high-thermal conductivity resins. As a result of the disclosed bobbin designs, the achievable power density is increased while maintaining acceptable temperatures.

摘要： In an embodiments, a coil component 10 is constituted by a drum core 20, a ring core 30, and a resin base 70. A metal plate is embedded in the resin base 70, terminal electrodes 50A, 50B are exposed on a mounting surface side, and connecting parts 52A, 52B internally connected with the terminal electrodes 50A, 50B are pulled out from side surfaces 74A, 74B of the resin base 70. A coating 44 is laser-stripped from lead parts 46A, 46B at both ends of the winding wire 40 wound around a winding shaft 22 of the drum core 20. An end of the conductive wire 42, from which the coating 44 is stripped, is sandwiched by the connecting parts 52A, 52B and securing parts 54A, 54B, and joined together by laser irradiation, forming joining parts 56A, 56B which are separated from the coating end 45.
