Wireless power transmission device and control method therefor
摘要
說明書
An active area and a detection area may be different according to the wireless power transfer method of the wireless power transmitter 100. Therefore, the wireless power transmitter 100 may determine whether there is a wireless power receiver located on the active area or the detection area according to the resonance coupling method or a wireless power receiver located on the active area or the detection area according to the induction coupling method. According to the determination result, the wireless power transmitter 100 which supports each wireless power transfer method may change the power transfer method for each wireless power receiver.
In the wireless power transfer according to the exemplary embodiments disclosed herein, when the wireless power transmitter 100 transfers power to the one or more electronic devices 200 and 200′ according to the same wireless power transfer method, the electronic devices 200 and 200′ may perform communications through the wireless power signals without inter-collision.
