Abstract: Disclosed is a wireless power receiving apparatus controlling an output voltage. The wireless power receiving apparatus may include a first rectifier to which a first coil receiving power from a wireless power transmitting apparatus and a first capacitor are connected, a second rectifier to which a second coil receiving power from the wireless power transmitting apparatus and a second capacitor are connected, a first switch connected to one end of the first rectifier, and a second switch and a third switch connected to both ends of the second rectifier, in which the first rectifier and the second rectifier are connected in parallel, and an operation mode of the wireless power receiving apparatus may be determined based on whether the first switch, the second switch, and the third switch are turned on or off.
