Coil Component Coupling Coefficient Control

The patent applies local quality by making the separation distance between turns non-uniform, specifically making the separation distance between adjacent turns of different coils different from the separation distance between adjacent turns of the same coil. This local variation in spacing enables control of the coupling coefficient between first and second coils while maintaining a regular winding pattern within each individual coil, thus achieving both manufacturing simplicity and coupling control.

The patent employs parameter changes by varying the separation distance between turns as a geometric parameter to control the coupling coefficient. By adjusting this separation distance parameter during manufacturing, the coupling coefficient can be optimized for different applications requiring different leakage inductance values, while the overall array-type structure and manufacturing process remain relatively simple.

The patent resolves this contradiction by applying local quality to the separation distance parameter in the array-type coil structure. By making the separation distance between adjacent turns of different coils different from that of the same coil, the design achieves compact array-type packaging while providing a straightforward method to control coupling coefficient through this localized geometric parameter.
