Abstract

Provided is a receiving unit for a wireless power system that wirelessly transmits power. The wireless power system is configured such that coils for transmitting or receiving electrical energy are arranged, each coil is wound to form first to nth turns, each coil has a multi-layer structure of two or more layers, the coils overlap one another, and each coil has a dummy coil having a separate current flow path. Thus, the wireless power system exhibits the effects of selectively receiving wireless power according to the condition of a wireless power transmitting unit, and obtaining improved receiving efficiency.
