RADIO POWER TRANSMITTER CORE ASSEMBLY AND RADIO POWER TRANSMITTER INCLUDING THE SAME

PROBLEM TO BE SOLVED: To provide a radio power transmitter core assembly capable of increasing a degree of freedom of a home position at which a radio power receiver for receiving power from the radio power transmitter should be placed, and minimizing reduction in power transmission efficiency due to inclusion of a structure for increasing the degree of freedom; and a radio power transmitter including the same.SOLUTION: A radio power transmitter core assembly includes: a main coil 111 disposed so as to be positioned at a first level; an auxiliary coil disposed below the main coil 111 so as to be positioned at a second level lower than the first level, and including a first sub-coil 112 and a second sub-coil 113, being partially overlapped with each other and each having a size smaller than a size of the main coil 111; and a magnetic core formed so as to store the main coil 111 and the auxiliary coil.
