Abstract
A power transmission control device controls a power transmission device in a contactless power transmission system that transmits power from the power transmission device to a power reception device through electromagnetically coupling a primary coil and a secondary coil. The power transmission control device includes a power transmission driver control section that controls drive timings of a plurality of switching elements of a power transmission driver that drives the primary coil, the power transmission driver control section variably controlling the power to be transmitted from the power transmission device to the power reception device.
