The purpose of the present invention is to suppress an increase in power when a short circuit is formed by the operation of a switching element. A power receiving device comprises: a receiving coil that receives power transmitted non-contactlessly from a transmitting coil of a power transmitting device; a rectifier circuit formed between the receiving coil and a load; a smoothing capacitor formed between the rectifier circuit and the load; and a control device that executes a short-circuit mode for short-circuiting output terminals of the receiving coil by switching a switching element formed in the rectifier circuit. The control device comprises: an acquisition unit that acquires information indicating a driving frequency of an inverter formed in the power transmitting device; a setting unit that sets the switching frequency of the rectifier circuit to a value different from the driving frequency of the inverter; and a control unit that executes the short-circuit mode based on the switching frequency set by the setting unit.
