Abstract
A wireless power transmitting apparatus wirelessly charging a wireless power receiving apparatus is provided. The wireless power transmitting apparatus includes a power providing unit configured to provide power, a gate driver configured to generate a differential signal formed of a first signal and a second signal from the power provided from the power providing unit, an amplifier configured to amplify the differential signal by a predetermined gain, a power transmitting unit configured to transmit the amplified differential signal to the wireless power receiving apparatus, and a differential signal correcting circuit that is disposed between the gate driver and the amplifier and is configured to correct the differential signal so that a predetermined phase difference between the first signal and the second signal is maintained.
