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 Nreceiving coils disposed to be partially overlapped on the same plane so as to receive wireless power signals; first to Noutput terminals formed to enable both ends of each of the first to Nreceiving coils to be connected thereto so as to transfer alternating current power induced by at least any one among the first to Nreceiving coils; and a rectifier for converting, into direct current power, the alternating current power to be input from the first to Noutput terminals. Therefore, the present invention has an advantage of minimizing charging interruptions and minimizing manufacturing costs of a wireless power transmitting device.
