Abstract

The present invention discloses an adjustable frequency wireless charging transmitter side module which comprises a coil with a plurality of leads, a magnetic isolation shim for enhancing wireless charging efficiency, and a control IC for controlling wireless charging frequency, wherein the coil with a plurality of leads is positioned on an upper layer and is attached to the magnetic isolation shim for enhancing wireless charging efficiency. The control IC for the wireless charging frequency can be matched according to a charging device and can select different leads of the coil with a plurality of leads to adjust the charging frequency for performing electromagnetic coupling for different devices to provide power. The adjustable frequency wireless charging transmitter side module solves the problem that different devices have inconsistent requirements for the wireless charging frequency, greatly improves the concept and reality of consumers for troublesome management of a wireless charging device, and further reduces the use cost of the consumers for a wireless charging transmitter side.

Description

technical field [0001] The invention relates to the field of wireless charging, in particular to an adjustable-frequency wireless charging transmitter module. Background technique [0002] In recent years, wireless charging technology has gradually become popular with the development of smart phones, and more and more electronic devices have begun to use this technology to charge their own devices. Among the international mainstream wireless charging technologies, the most widely used is to charge devices through electromagnetic induction, and the Qi standard and PMA standard are the most widely used. The Qi standard is the wireless charging interface standard launched by WPC (Wireless Power Consortium), the world's first wireless charging technology standardization organization. It adopts the most mainstream electromagnetic induction technology, and the electromagnetic wave frequency is between 100-205kHz. 15W of power for wireless power transfer. The PMA standard is a wi...
