Abstract

The present invention relates to a multi-mode wireless power transmission method and a device for the same. A wireless power transmitter for supporting a plurality of wireless power transmission modes, according to one embodiment of the present invention, can comprise: a first transmitter for transmitting a first power signal corresponding to a first wireless power transmission mode; a second transmitter for transmitting a second power signal corresponding to a second wireless power transmission mode; and a first power cutoff circuit coupled to the first transmitter so as to block the incoming second power signal and allow the first power signal to pass therethrough. Therefore, the present invention can minimize power consumption in the wireless power transmitter supporting the plurality of wireless power transmission modes, and can maximize power transmission efficiency.
