Abstract
A non-contact charging station with a planar-spiral power transmission core, a non-contact power-receiving apparatus, and a method for controlling the same. A primary core of the non-contact charging station transmitting a power signal to a portable device using an induced magnetic field and a secondary core of the non-contact power-receiving apparatus are configured as a power transmission Printed Circuit Board (PCB) core in which a planar-spiral core structure is formed on a core base. The power transmission PCB core has a simplified shape along with improved applicability that facilitates its mounting on a non-contact charger. In addition, the receiving core has a reduced volume to reduce the entire size of the power-receiving apparatus so that it can be easily mounted onto a portable device.
