This power receiving device is capable of receiving alternating current power in a wireless manner from a power supply device. The power receiving device includes a secondary coil, a variable load, a first impedance conversion unit, a second impedance conversion unit, a fixed load, and a switch. The secondary coil is capable of receiving the alternating current power from a primary coil. The variable load has the impedance thereof varied corresponding to the power value of power inputted thereto. Each of the first and the second impedance conversion units is provided between the secondary coil and the variable load, and has the impedance thereof configured so as to be variable. The fixed load has the same impedance irrespective of the power value of power inputted thereto. The switch receives power by means of the secondary coil, and performs switching between the fixed load, and the second impedance conversion unit and the variable load, to which the alternating current power is outputted from the first impedance conversion unit.
