| description | A power transmitter that wirelessly transmits power to a power receiver includes a power converter that converts power fed from a power source into first direct current (DC) power, an inverter circuit that converts the first DC power into first alternating current (AC) power, a power transmission coil that generates a magnetic field based on the first AC power, and is magnetically coupled with a power reception coil included in the power receiver, a sensor that detects a current value and a voltage value of the first DC power, and a controller that controls the power converter, wherein the controller controls the power converter to raise a voltage of the first DC power up to a first voltage value lower than a predetermined power feeding time voltage value predetermined, and determines whether power is not allowed to be fed to the power receiver based on the current value of the first DC power when the voltage of the first DC power is the first voltage value. |
