US 2019/0356152 A1 · INDUCTIVELY COUPLED WIRELESS CHARGER

Abstract

An inductively coupled wireless charging system produces a high magnetic flux density to induce voltages in one or more coils of an electronic device via magnetic induction. These induced voltages are used to operate or charge batteries in the one or more electronic devices. The high magnetic flux density may cause electromagnetic interference to other adjacent devices, including other adjacent wireless charging systems. Methods, systems, and devices of the present disclosure are directed to reducing interference among adjacent wireless charging systems during concurrent operation of the adjacent wireless charging systems.

Dependent claims

A wireless charging system for reducing interference in adjacent active wireless charging components comprising:

a first wireless charging component comprising a first resonant circuit, the first charging component operatively coupled to a first electronic device;
and
a second wireless charging component comprising a second resonant circuit, the second charging component being located adjacent to the first charging component and operatively coupled to a second electronic device, wherein a first resonant frequency of the first resonant circuit is different than a second resonant frequency of the second resonant circuit.
