Title: WIRELESS POWER TRANSMISSION APPARATUS AND METHOD FOR CONTROLLING SAME
Abstract:
A transmission antenna (201) includes a transmission coil (202), and transmits a power signal (S2). A driver (204) applies a drive signal (S1) to the transmission antenna (201). A first temperature sensor (242) measures a temperature (T1) of the transmission coil (202), and generates a first temperature signal (S11). A second temperature sensor (244) measures a temperature (T2) of an interface table (240) having an electronic apparatus (320) mounted thereon, said electronic apparatus having a wireless power receiving apparatus mounted therein, and the second temperature sensor generates a second temperature signal (S12). A control circuit (220) controls the power signal (S2) corresponding to a difference between the first temperature signal (S11) and the second temperature signal (S12).
