Abstract

A wireless power receiver is disclosed. A wireless power receiver according to various embodiments of the present disclosure includes a resonant reception unit configured to receive wireless power by a resonance scheme; an inductive reception unit configured to receive wireless power by an induction scheme; and a power processing unit configured to process wireless power received at resonant reception unit and the inductive reception unit. When the wireless power is received by the induction scheme, a current flowing in the inductive reception unit is greater than a current flowing in the resonant reception unit, and when the wireless power is received by the resonance scheme, a current flowing in the resonant reception unit is greater than a current flowing in the inductive reception unit.

Description

Technical field [0001] The present disclosure relates to a wireless power receiver, and more particularly, to a wireless power receiver for wirelessly receiving power from a wireless power transmitter. Background technique [0002] Mobile terminals such as mobile phones or personal digital assistants (PDAs) are usually powered by rechargeable batteries. In order to charge such a rechargeable battery, electric energy is supplied to the rechargeable battery via a separate charging device. Generally, the charging device is electrically connected to the rechargeable battery through contact terminals formed on the charging device and the rechargeable battery. [0003] However, in the contact charging scheme, the contact terminals may be contaminated with foreign matter, resulting in unstable battery charging. In addition, if the contact terminal is exposed to moisture, battery charging may not be performed correctly. [0004] Therefore, non-contact or wireless charging technology has r...
