Planar array coil for stable power conversion operations
The patent US12046404B2 describes a planar array coil designed for use in power supply devices. The invention features a multilayer substrate that accommodates multiple coils, each consisting of two parts with currents flowing in opposite directions. These coils are strategically arranged so that one part of a coil is adjacent to another part of a different coil, with a specified distance between them that is equal to or less than the opening width of the coils. The design aims to enhance the efficiency of the coils by ensuring that the currents in adjacent coil parts flow in the same direction when connected to a power conversion circuit.
Additionally, the patent outlines various configurations of the conductor patterns within the coils, which include linear-shaped central conductors and coil-shaped patterns. These patterns can be ring-shaped or spiral-shaped, and they are arranged across multiple base material layers within the multilayer substrate. The invention also includes a magnetic sheet that can be laminated over the coils to improve performance. The claims further detail the interlayer connections that facilitate current flow between the different conductor patterns, emphasizing the innovative arrangement of the coil parts and their connections, which contribute to the overall functionality of the switching power supply device.
