A power receiving device receives alternating current power in a wireless manner from a power supply device including a primary coil that receives the alternating current power. 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 switch switches an output destination, to which the alternating current power received by the secondary coil is output from the first impedance conversion unit, to the fixed load or to the second impedance conversion unit and the variable load.
