    摘要: Magnetic devices, and associated methods of manufacture, using flex circuits. Conductive flex circuit traces, or combinations of such traces with conductive printed circuit board or other substrate traces, form windings around toroidal ferromagnetic cores. Bending the flex circuit into a partial loop or a full loop forms partial or full windings respectively. Bonding or flow soldering electrically connects the windings together and to a printed circuit board or other substrate. The methods yield transformers with high conversion efficiency, are compatible with conventional printed circuit boards and readily available high-volume assembly equipment, and avoid the higher cost of manually made windings.

    摘要: An improved structure of an SMD (Surface Mount Device) includes a magnetic core and a plurality of conductive wire. The magnetic core has two ends each forming a connection portion and the connection portion has a side forming at least four soldering sections. The conductive wires are wound around the magnetic core and two ends of each of the conductive wires are respectively soldered to the soldering sections. The conductive wires are subjected to a mechanized automatic winding operation. The magnetic core is an SMD core. With such an arrangement, the volume of the signal transformer can be greatly reduced. Further, an advantage of human-labor-free manufacture can be achieved with the mechanized winding operation and also, the quality of the signal transformer is made more stable to increase the throughput. Advantages including stable electric characteristics, fully automatized manufacture, and high throughput, can be achieved.

    摘要: Provided is a transmission line transformer having increased signal efficiency. The transmission line transformer is formed on an integrated circuit (IC), wherein a first transmission line disposed in one direction. Second and third transmission lines have same length direction as the first transmission line and are spaced apart from each other in a lateral direction above or below the first transmission line. Accordingly, an area of the first transmission line and areas of the second and third transmission lines, which face each other, are increased, thereby improving a coupling factor. Also, since a secondary transmission line is divided into two regions and uses the second and third transmission lines that have narrower widths than the first transmission line, parasitic capacitance components generated between the first through third transmission lines and a semiconductor substrate may be decreased.

    摘要: A current transformer is provided for the electronic trip unit of a molded case circuit breaker. The current transformer has a core with a winding encoiled about the core and a bus spiraled about the core. The spiral bus establishes a current path from one end of the bus to the other which will conduct current through the core in a spiral fashion. The spiral bus design effectively rotates the bus 90 degrees achieving a narrow transformer design which fits into the electronic trip unit without increasing the width of the trip unit.

    摘要: A transformer comprising an outer coil former (1) having a first outer end portion (13), to which is secured a resilient device (49) which exerts a force on a first core part (47) directed towards a second outer end portion (15) of the outer coil former. Within the outer coil former (1) is arranged an inner coil former (3) having a first inner end portion (25), which is received by a recess in the first outer end portion (13) in a manner such that the resilient device engages only the first outer end portion and the first core part (47) but does not engage the first inner end portion. As a result, the resilient device not only holds the first core part in position, but also prevents the two coil formers (1,3) from moving away from each other.
