A wireless power receiving apparatus comprises a receiving coil, a rectifying unit, a signal detection unit, a control unit, and a modulation unit. The receiving coil receives AC power from a wireless power transmitting apparatus. The rectifying unit rectifies the received AC power into DC power and delivers the DC power to a load terminal. The signal detection unit detects a signal from the rectifying unit. The control unit identifies a state of the load terminal based on the signal detected by the signal detection unit. The modulation unit is arranged between the receiving coil and the rectifying unit. The modulation unit is modulated by a control signal of the control unit. By the modulation of the modulation unit, information is provided from the receiving coil to a transmitting coil of the wireless power transmitting apparatus. |
