Title:
COIL AND WIRELESS CHARGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/052183
Kind Code:
A1
Abstract:
A coil and a wireless charging device. Coils are arranged in a spaced and crossed manner to achieve a symmetrical coil distribution in which head ends are connected to tail ends; that is, the coil closest to an input port and the coil closest to an output port form a group, the coil second closest to the input port and the coil second closest to the output port form a group, and so on. The lengths of two coils in each group are equal, such that the coil current distribution is more uniform and the magnetic field distribution is more uniform, thereby reducing alternating current resistance.
