| 20150302969 | Transformer with Improved Power Handling Capacity - Disclosed is an electrical transformer for improved transformer power capacity and efficiency designed by the application of disclosed design considerations. One embodiment design consideration is a method to configure power transformer windings wherein the minimum distance of the primary windings from the winding axis/core center is greater (the primary windings are more distal) from the winding axis than the minimum distance of the secondary windings, which are wound around the minimum interior core diameter. This design consideration is extended from single bobbin transformer designs to split bobbin designs, with the requisite distal increase of the primary windings (from the core axis) geometrically provided by an enlarged core bobbin center leg (axial) dimension beneath the primary winding window. Another disclosed design consideration is to fix the primary winding length relationship to the core weight for given transformer specifications in accordance with the disclosed unexpected experimental results and formula. | 10-22-2015 |
| 20150302978 | BOBBIN STRUCTURE WITH WINDING GROOVES FOR ADJUSTING COUPLING - A bobbin structure with winding grooves for adjusting coupling at least includes: a bobbin body, a hole provided in the bobbin body for allowing magnetic wires to pass through, and at least three separated winding grooves with different lengths provided around the outer peripheral side of the hole. The primary winding (or the secondary winding) of the coils of a transformer is selectively wound into one of the winding groove, while the secondary windings (or the primary windings) are wound into the rest of the winding grooves. By altering the numbers of turns of the secondary windings (or the primary windings) distributed in the winding grooves, different coupling effects can be achieved with respect to the primary winding (or the secondary winding). As a result, the transformer leakage inductance and the output impedance can be conveniently adjusted. The design of multiple grooves also reduces the stray capacitances of the windings, thereby increasing the bandwidth of the transformer. | 10-22-2015 |
| 20150364245 | COIL COMPONENT AND POWER SUPPLY UNIT INCLUDING THE SAME - The coil component includes a core, first and second coil parts coupled to the core while being stacked with each other, and an insulating member accommodating the second coil part therein. In addition, the second coil part is formed of a flat-type wire. | 12-17-2015 |
| 20160005529 | WINDING LAYER PITCH COMPENSATION FOR AN AIR-CORE REACTOR - A winding layer pitch compensation for an air-core reactor which has at least two radially spaced apart concentric winding layers, includes a first set of strip-shaped star sheets, each of which is configured to be arranged radially below or above the winding layers and which are provided with at least one receiving slot along an edge extending from that edge, a second set of strip-shaped compensation sheets, each of which is provided with at least one insert slot along an extending from another edge, where a compensation sheet can be inserted into each receiving slot of a star sheet in a formfitting manner, where the star sheet engages into the insert slot of the compensation sheet in a formfitting manner, and where the slot depths of at least two receiving slots of the set of star sheets are different. | 01-07-2016 |

| 20160086724 | SEGMENTATION OF WINDING SUPPORT STRUCTURES - The present invention provides a method of manufacturing magnets, including magnets comprising coil windings which may be multiple meters in length. In an embodiment, the support structure comprises a cylinder in which machined grooves are formed to define the magnet conductor path. The segments may consist of a composite material or a metal in the shape of a cylinder, but which need not be manufactured from a single piece of material. Rather, the support structure may be formed in multiple connectable segments which, when connected together, form a completed wiring support structure. Each segment may be of sufficient length to support multiple individual coil turns in a helical configuration. When the segments are connected the helical configuration continues without interruption from connectable segment to connectable segment. The segmented wiring support structure of the invention may be applied to linear or curved magnet geometries. | 03-24-2016 |
