Abstract:
A control device controls a power transmission driver that transmits power to a power receiving device including a rectifier circuit that is connected to a secondary coil and generates a rectified voltage, by outputting a drive signal to a primary coil. The control device switches the drive mode of the power transmission driver between a full-bridge drive mode and a half-bridge drive mode according to the rectified voltage.
