Abstract

Provided is a dual-purpose device for inductively coupled power transfer and electric field coupled power transfer. The device comprises a power converter, a control circuit, a wireless communication receiving circuit and a metal flat plate. The power converter receives an input voltage and converts the input voltage into a specific voltage. The control circuit is used for controlling the power converter. The wireless communication receiving circuit is used for receiving a power identification signal, wherein the power identification signal is from power demand information of a first or second external device. The metal flat plate is coupled to the power converter. When in an inductively coupled power transfer mode, the control circuit causes the power converter to output magnetic field power to charge the first external device. When in an electric field coupled power transfer mode, the control circuit causes the power converter to output high-frequency and high-voltage power to the metal flat plate in order to output electric field power to charge the second external device.

Description

technical field [0001] The invention relates to a wireless charging technology, and in particular to a dual-purpose circuit for inductive coupling power transmission and electric field coupling power transmission. Background technique [0002] With the reduction in weight and thickness of electronic devices, users have gradually become accustomed to carrying these electronic devices with them. Common electronic devices, such as mobile phones, personal digital assistants (PDA, Personal Digital Assistance), notebook computers, tablet computers, digital cameras and digital video recorders (digital camcorder), etc., have been widely used by the public and have become modern An integral part of information life. [0003] In order to reduce the trouble of wiring and charging, the concept of a system that uses the principle of electromagnetic induction to provide wireless power has been proposed many years ago. Existing wireless charging systems are considerably limited due to pr...
