Abstract
A control device controls a first power transmission driver that applies a first drive signal to a first primary coil and a second power transmission driver that applies a second drive signal to a second primary coil. When intermittent power transmission is performed by applying the second drive signal in a period in which normal power transmission is performed by applying the first drive signal, a controller of the control device sets the phase difference between the first drive signal and the second drive signal to a predetermined phase difference.
