Wireless power receiver and controlling method thereof
First Claim
1. A method for controlling an electronic device including a charging circuit, the method comprising:
- receiving power wirelessly from a power transmitting device;
rectifying, through a rectifying circuit of the electronic device, the received power;
comparing a voltage of the rectified power with an allowable voltage of the charging circuit;
in response to the voltage of the rectified power being greater than or equal to the allowable voltage of the charging circuit, controlling a converting circuit of the electronic device to convert the rectified power and to output the converted power to the charging circuit for charging a battery of the electronic device, wherein the allowable voltage relates to a maximum voltage or a preferable voltage to be applied to the charging circuit; and
in response to the voltage of the rectified power being less than the allowable voltage of the charging circuit, controlling to output the rectified power directly to the charging circuit by allowing the rectified power to bypass the converting circuit.

Abstract
A method for controlling an electronic device including a charging circuit is provided. The method includes receiving power wirelessly from a power transmitting device; rectifying the received power; based on a voltage of the rectified power being greater than or equal to an allowable voltage of the charging circuit, controlling to convert the rectified power through a converting circuit of the electronic device and to output the converted power to the charging circuit for charging a battery of the electronic device, wherein the allowable voltage relates to a maximum voltage or a preferable voltage to be applied to the charging circuit; and based on the voltage of the rectified power being less than the allowable voltage of the charging circuit, controlling to stop converting the rectified power and to output the rectified power to the charging circuit by connecting the rectifying circuit to the charging circuit.
