A non-contact charging control device for controlling a power receiving device capable of non-contact charging to charge a battery by non-contact receiving power from a power transmission device, includes: a transformer of a power receiving side for receiving an AC power having a transmission frequency transmitted from a transformer of a power transmission side; a rectifier circuit for converting the AC power received by the transformer of the power receiving side into DC power and outputting the DC power to the battery; a smoothing capacitor, provided between the rectifier circuit and the battery, for smoothing a current from the rectifier circuit; a voltage sensor for detecting a voltage of the smoothing capacitor; and a controller, when an overvoltage of the smoothing capacitor is detected, reduces a voltage phase difference between the transformer of the power transmission side and the transformer of the power receiving side.
