The invention provides a power transmission device and a power supply system. Even during power transmission, foreign matters can be detected only through control of a power transmission unit monomer. A power transmission device according to an embodiment includes a power transmission unit that transmits power to a power receiving unit in a state of being disposed facing the power receiving unit, and a control unit that controls the power transmission unit. The control unit periodically and temporarily stops a normal power transmission process for supplying power for charging to the power receiving unit, performs a foreign matter detection process for detecting a foreign matter disposed between the power transmitting unit and the power receiving unit in a state in which the normal power transmission process is stopped, and restarts the normal power transmission process when no foreign matter is detected.
一种送电装置及供电系统,即使在送电中也可以仅通过送电部单体的控制而检测异物。实施方式涉及的送电装置具备:以与受电部对置配置的状态向所述受电部送电的送电部、以及控制所述送电部的控制部。所述控制部使向受电部供给充电用的电力的通常送电处理定期且暂时停止,在所述通常送电处理停止的状态下进行检测配置于所述送电部与所述受电部之间的异物的异物检测处理,并在未检测到异物时再次开始所述通常送电处理。
