WIRELESS CHARGING TRANSCEIVER DEVICE AND WIRELESS CHARGING CONTROL METHOD

摘要

A wireless charging transceiver device includes an energy storage module, a coil, a switch module, a rectifier circuit, and a resonant circuit. The coil is used to induce an external magnetic field or receive an external charging signal, and is used to transmit a wireless charging signal. The switch module is used to be coupled between the energy storage module and the coil through a first or second electrical path. The rectifier circuit is coupled between the energy storage module and the switch module, and is sited in the first electrical path, and rectifying a first inducing current which is induced from the external magnetic field in a first mode. The resonant circuit is coupled between the energy storage module and the switch module, and is sited in the second electrical path.
