Abstract: Provided are a method and apparatus for wirelessly transmitting energy. A wireless energy transmitter may perform sampling to obtain first samples from an alternating current (AC) signal that is induced at an energy transmission (TX) end, and may correct symbol synchronization based on a difference between a sum of absolute values of the first samples and a sum of absolute values of second samples sampled during a symbol interval in which synchronization matching is performed between a switch of the energy TX end and a switch of the energy RX end.
