Abstract
Structures, devices, and methods for wireless power transfer systems are described. A structure can include a plurality of strands a plurality arranged into a coil layer. For every fixed interval along a length of the structure, the plurality of strands can be folded at a lateral angle and vertically inverted in response to being folded at the lateral angle. The plurality of strands being folded can cause the plurality of strands to surround a center of the structure in a parallel path.
Claims17
A structure comprising:
- a plurality of strands arranged into a coil layer, wherein:
- the plurality of strands are flat rectangular wires arranged directly adjacent to one another;
- for every fixed interval along a length of the structure, the plurality of strands are folded at a lateral angle and vertically inverted in response to being folded at the lateral angle;
- and
- the plurality of strands being folded causes the plurality of strands to surround a center of the structure in a parallel path.
A device comprising:
- a power rectifier configured to rectify alternating current (AC) power into direct current (DC) power;
- a controller connected to the power rectifier, the controller being configured to control the power rectifier;
- a structure configured to receive the AC power, the structure including a plurality of strands arranged into a coil layer, wherein:
- the plurality of strands are flat rectangular wires arranged directly adjacent to one another;
- for every fixed interval along a length of the structure, the plurality of strands are folded at a lateral angle and vertically inverted in response to being folded at the lateral angle;
- and
- the plurality of strands being folded causes the plurality of strands to surround a center of the structure in a parallel path.
A method for constructing a coil of a device, the method comprising:
- arranging a plurality of strands in a parallel path, wherein the plurality of strands are flat rectangular wires arranged directly adjacent to one another;
- and
- at every fixed point along the parallel path, folding the plurality of strands at a lateral angle to vertically invert the plurality of strands, wherein the folding causes the plurality of strands to form a loop surrounding a center point.
