COIL STRUCTURE FOR INDUCTIVE AND RESONANT WIRELESS CHARGING TRANSMITTER AND INTEGRAL CONTROL METHOD FOR THE SAME

摘要

A wireless power transmitter according to the present invention includes a first coil arranged for wireless power transmission, a second coil positioned outside the first coil for the wireless power transmission, and a control unit which operates the first coil and does not operate the second coil when operated in a magnetic induction mode, and integrally operates the first and second coils when operated in a magnetic resonance mode. Accordingly, the present invention can support both inductive and resonant terminals.
