  "textContent": "A power receiving device includes: a power receiving coil receiving power transmitted from a power transmission coil; a rectifier circuit between the power receiving coil and a load; a smoothing capacitor between the rectifier circuit and the load; and a control device executing a short-circuit mode of short-circuiting between output ends of the power receiving coil. Further, the control device includes an acquisition unit acquiring information indicating a drive frequency of an inverter in the power transmission device, a setting unit setting a switching frequency of the rectifier circuit to a value different from the drive frequency of the inverter, and a control unit executing the short-circuit mode based on the switching frequency set by the setting unit.",
