A power supply device is capable of transferring AC power in a noncontact manner to a secondary coil of a power receiving device. The power supply device includes an AC power supply that outputs the AC power. The AC power supply includes a DC/AC conversion unit that converts DC power to the AC power, which has a predetermined frequency. A primary coil receives the AC power. A control unit controls the AC power output from the AC power supply. The control unit is configured to suspend the output of the AC power from the AC power supply or decrease the AC power based on input power, input current value, output power, or output current value of the DC/AC conversion unit and a power factor or a current difference of the input current value and the output current value.
