| 336189000 | COIL WITH CROSSED TURNS | 6 |
| 20100328008 | DISC WINDING - A disc winding of a power transformer or a choke is provided. The disc winding includes a plurality of parallel single strand conductors. The working time for bending the strand conductors of cross-overs is reduced by sharing the winding axially in plurality of sections, and the cross-overs within a section are identical twin cross-overs. The the strand conductors are bent in two groups, and a standardized twin transposition cross-over is provided between the sections such that the strand conductors are being bent in two groups. The outermost strand conductor is in the first group, and the remaining strand conductors are in the other group. | 12-30-2010 |
| 20110090035 | COIL - In the winding wire at the winding completion end side, two wires are piled up vertically and wound together from the inner circumferential side towards the outer circumferential side. The winding wire at the winding start end side that has remained on the inner circumferential side is drawn forth from the inner circumferential side to the outer circumferential side so as to form a curve along the flat surface of the coil. In the crossing portions of the winding wire at the winding completion end side and the winding wire at the winding start end side, the two wires of each winding wire are superimposed and caused to cross each other in a state in which the wires are laid down transversely. | 04-21-2011 |
| 20110148558 | INDUCTOR - An inductor includes a conductive track forming at least three inductor turns. The conductive track has a plurality of track sections. The inductor also includes at least two groups of crossing points, each crossing point comprising a location at which the conductive track crosses over itself. The crossing points of each group collectively reverse the order of at least some of the track sections in the inductor, such that inner track sections of the conductive track cross over to become respective outer track sections, and such that outer track sections of the conductive track cross over to become respective inner track sections. | 06-23-2011 |
| 20150348697 | COIL CONSTRUCTIONS FOR IMPROVED INDUCTIVE ENERGY TRANSFER - An inductor coil for an inductive energy transfer system includes multiple layers of a single wire having windings that are interlaced within at least two of the multiple layers such that both an input end and an output end of the wire enter and exit the coil on a same side of the coil. The input end and the output end of the wire may abut one another at the location where the input and output wires enter and exit the inductor coil. The wire can include one or more bundles of strands and the strands in each bundle are twisted around an axis extending along a length of the wire, and when there are at least two bundles, the bundles may be twisted around the axis. At least one edge of the inductor coil can be formed into a variety of shapes, such as in a curved shape. | 12-03-2015 |
| 20160118181 | Transformers - A transformer may comprise a winding wrapped around a magnetic core, the winding having at least one winding portion extending between the magnetic core and the exterior of the winding in radial direction. The winding may comprise at least a first conductor and at least a second conductor, arranged radially adjacent to each other in each winding portion with the interposition of an insulating layer, wherein the first conductor is arranged radially inwardly with respect to the second conductor for part of each winding portion length, and radially outwardly with respect to the second conductor for another part of each winding portion length. | 04-28-2016 |
| 20160125995 | ARRAY OF INTERLEAVED 8-SHAPED TRANSFORMERS WITH HIGH ISOLATION BETWEEN ADJACENT ELEMENTS - An apparatus configured to isolate a direct current component voltage of a first circuit from a direct current component voltage of a second circuit in which the apparatus includes a first conductor and a second conductor. The first conductor has a first portion disposed to substantially enclose a first area, a second portion disposed within the first area, a third portion disposed to substantially enclose a second area, and a fourth portion disposed within the second area, the second area lacking an intersection with the first area. The second conductor is configured to be magnetically coupled to the first conductor and has a fifth portion disposed between the first portion and the second portion and a sixth portion disposed between the third portion and the fourth portion. | 05-05-2016 |
