WIRELESS POWER TRANSMITTER SUPPORTING MULTIPLE MODES

WIPO Patent Application WO/2017/111369

A1

The present invention relates to a wireless power transmission technology and, more particularly, to a wireless power transmitter capable of increasing the probability that wireless power transmission will succeed, thereby improving performance. A wireless power transmitter according to an embodiment of the present invention comprises: a first coil printed circuit board (PCB) comprising an induction coil for transmitting a power signal in a first frequency band to a wireless power receiver coil having a first coupling coefficient; a second coil PCB formed on the upper or lower portion of the first coil PCB, the second coil PCB comprising a resonance coil for transmitting a power signal in a second frequency band to a wireless power receiver coil having a second coupling coefficient; and a control circuit PCB formed beneath the first and second coil PCBs so as to control the induction coil and the resonance coil, wherein the induction coil has a charging area on the upper portion of the first coil PCB, the resonance coil has a charging area on the upper portion of the second coil PCB, and the charging area of the induction coil may at least partially overlap with the charging area of the resonance coil.
