Abstract: A wireless electric power transmitter for transmitting electric power for a charging function to a wireless electric power receiver is provided. The wireless electric power transmitter includes an electric power supply unit which supplies electric power; an amplifier which amplifies and outputs the electric power supplied from the electric power supply unit by a preset gain as a magnitude of measured impedance increases; and a transmitter which transmits the amplified electric power to the wireless electric power receiver.

Abstract: Provided is a method in which a Digital Pre-Distorter (DPD) performs digital pre-distortion on a received In-phase (I) signal, a received Quadrature-phase (Q) signal, a feedback I signal, and a feedback Q signal; a mixer mixes a signal output from the DPD with a frequency signal output from an oscillator; each of n phase shifters phase-shifts a signal output from the mixer according to a preset beamforming pattern; each of n Power Amplifiers (PAs) amplifies a signal output from an associated phase shifter according to a gain, the PAs connected to the associated phase shifter on a one-to-one basis; each of n envelope detectors detects an envelope signal from a signal output from an associated PA, the envelope detector connected to the associated PA on a one-to-one basis; and a control unit determines whether the n PAs operate normally, using the envelope signals output from the n envelope detectors.
