Abstract

Provided is a wireless power transmitter for wirelessly transmitting power to a wireless power receiver. A wireless power transmitter according to various embodiments of the present invention comprises: a drive unit for supplying power; and a power transmission unit for wirelessly transmitting power to a wireless power receiver on the basis of the power received from the drive unit, wherein the power transmission unit may comprise: a capacitor; a first coil which is connected to the capacitor; and a second coil which is connected to the capacitor and arranged so as to be parallel to the first coil.

Description

technical field [0001] The present disclosure relates to wireless power transmitters, and more particularly to wireless power transmitters for wirelessly transmitting power to wireless power receivers. Background technique [0002] Mobile terminals such as mobile phones, Personal Digital Assistants (PDAs), etc. are driven by rechargeable batteries due to their nature, and the battery of the mobile terminal is charged by supplying power to the battery using a separate charging device . Typically, the charging device and the battery each have separate contact terminals on their exteriors, and are electrically connected to each other by contacting these contact terminals. [0003] However, in such a contact charging scheme, the contact terminals protrude outward, and thus are easily contaminated by foreign matter. As a result, battery charging cannot be properly performed. Also, battery charging may not be performed properly if the contact terminals are exposed to moisture. ...
