Abstract
A wireless power transmitter includes: a converter including switching elements forming a bridge circuit and configured to output an alternating current (AC) voltage in response to control signals; a resonator including a resonant capacitor and a resonant coil, and configured to receive the AC voltage to transmit power wirelessly; and a controller configured to set a dead time at which a magnitude of the AC voltage is substantially zero in response to a signal received from a wireless power receiver.
