Abstract
To provide a wireless power receiving device, and a wireless power transmission device capable of improving the reliability of a protection circuit while preventing breakage of a circuit element upon occurrence of any abnormality, such as overvoltage or overcurrent. A wireless power receiving device includes a power receiving coil; a rectifier unit that performs full-wave rectification of the power received by the power receiving coil and supplies the power to a load; power-receiving-side detecting unit that detects an output voltage value or an output current value from the rectifier unit; and switching unit that short-circuits one of two current paths through the rectifier unit if the value detected by the power-receiving-side detecting unit exceeds a predetermined reference value.
