Abstract
In a stand-by state where a power receiving device is not mounted on a power transmission device, ON/OFF of a switching element that applies an AC voltage to an active electrode and a passive electrode is controlled. A controller detects a potential difference between the active electrode and the passive electrode, and determines that the power receiving device is mounted on the power transmission device when the potential difference has changed. The controller starts ON/OFF control of switching elements and starts power transmission to the power receiving device from the power transmission device. With this, a power transmission device capable of achieving reduction in power consumption in the stand-by state and a wireless power transmission system including the same can be provided.
