A wireless power transmitting apparatus transmits wireless power to a wireless power receiving apparatus and includes a transmission power control unit, an AC power generating unit, a transmission induction coil, and a transmission resonant coil. The AC power generating unit is operated in a half bridge operation mode and a full bridge operation mode and generates power of a square wave shape by using DC power. The transmission induction coil transmits the power of the square wave shape to the transmission resonant coil by electromagnetic induction. The transmission power control unit determines either the half bridge operation mode or the full bridge operation mode and supplies an AC power generation control signal corresponding to the determined operation mode to the AC power generating unit. |
