    • According to an embodiment, a power transmitting device includes a power supply unit, a power transmitting coil, a first switch, a piezoelectric element, and a first switch controller. The power supply unit is configured to generate a transmission power by using power supplied to a power input terminal. Once the first switch is turned on, the first switch electrically connects an external power supply and the power input terminal until the first switch is turned off next time. The piezoelectric element is disposed at a position at which a weight of a placed power receiving device can be detected. The piezoelectric element is configured to generate a detection power according to the weight of the placed power receiving device. The first switch controller is configured to generate a starting power by the detection power and switches the first switch to on by using the starting power.
    • 根据实施例,电力传输装置包括电源单元,发电线圈,第一开关,压电元件和第一开关控制器。 电源单元被配置为通过使用提供给电力输入端子的电力来产生发送功率。 一旦第一开关接通,第一开关将外部电源和电源输入端子电连接,直到第一个开关下一次关闭。 压电元件设置在可以检测放置的受电装置的重量的位置。 压电元件被配置为根据放置的电力接收装置的重量产生检测功率。 第一开关控制器被配置为通过检测功率产生启动功率,并通过使用起动功率将第一开关切换到接通状态。
