16. A wireless power transmitter comprising:
-
a switch circuit configured to receive a direct current (DC) voltage, convert the DC voltage to an alternating current (AC) voltage, and supply the AC voltage to a transmission resonator to supply wireless power to a reception resonator of a wireless power receiver; a detector configured to detect a transient event induced in the transmission resonator by the switch circuit; and a controller configured to; control the switch circuit to adjust a magnitude of the wireless power in response to a magnitude of the transient event being greater than or equal to a threshold, and adjust a magnitude of the DC voltage to adjust the magnitude of the wireless power in response to the magnitude of the transient event being less than the threshold. - View Dependent Claims (17, 18, 19, 20)
