Abstract

The present invention relates to a wireless charging system using a wireless charging system, and a device therefor. A wireless power receiving device according to one embodiment of the present invention may comprise: first to Nth receiving coils disposed to be partially overlapped on the same plane so as to receive wireless power signals; first to Nth output terminals formed to enable both ends of each of the first to Nth receiving coils to be connected thereto so as to transfer alternating current power induced by at least any one among the first to Nth receiving coils; and a rectifier for converting, into direct current power, the alternating current power to be input from the first to Nth output terminals. Therefore, the present invention has an advantage of minimizing charging interruptions and minimizing manufacturing costs of a wireless power transmitting device.

Dependent claims

A wireless power reception device comprising:

first to Nth reception coils disposed such that partial regions thereof overlap each other for receiving a wireless power signal;
first to Nth output terminals connected to both ends of each of the first to Nth reception coils for transferring alternating current power induced by at least one of the first to Nth reception coils;
and
a rectifier configured to convert the alternating current power, input from the first to Nth output terminals, into direct current power,
wherein each of the first to Nth reception coils has a fan shape,
wherein each fan shaped coil among the first to Nth reception coils overlaps with at least two other fan shaped coils among the first to Nth reception coils, and the first to Nth reception coils overlap to form a single circle shape,
wherein an area of each of the first to Nth reception coils exceeds ⅓ of an area inside the single circle shape, and
wherein the area of a corresponding coil among the first to Nth reception coils includes an outer region occupied by one or more turns of the corresponding coil and an inner region surrounded by the one or more turns of the corresponding coil.
