Abstract
Various embodiments of the present disclosure relate to an apparatus and method for controlling a differential signal of a wireless power transmitter. For example, an apparatus for controlling a differential signal of a wireless power transmitter may include a converter configured to convert a single signal into differential signals; an amplifier operably coupled to the converter and configured amplify power of the differential signals, thereby providing amplified differential signals; a gauge operably coupled to the amplifier and configured to measure a phase difference and amplitude between the amplified differential signals; and a controller for converting a pulse width of the differential signals by controlling the converter according to measurements by the gauge. Further, various embodiments of the present disclosure also include other embodiments other than the aforementioned embodiments.
