Abstract
A wireless power transmitter includes a common bridge circuit configured to apply a first alternating current (AC) voltage to a terminal of each of a first resonator and a second resonator of the resonators, a first sub-bridge circuit configured to apply a second alternating current (AC) voltage to another terminal of the first resonator while the first alternating current (AC) voltage is being applied to the terminal of the first resonator, and a second sub-bridge circuit configured to apply a third alternating current (AC) voltage to another terminal of the second resonator while the first alternating current (AC) voltage is being applied to the terminal of the first resonator.
