  • Patent number: 10848009
    Abstract: The rectifying device converts high-frequency power input from an input terminal into direct current power and outputs the direct current power from an output terminal. The rectifying device includes a rectifier that converts the high-frequency power into the direct current power, and an impedance changer having one end connected to a connection point of the rectifier and the output terminal and the other end to which reference voltage is applied such that impedance varies while having a negative correlation with respect to an absolute value of voltage of the direct current power. When the absolute value of the voltage of the direct current power is greater than a predetermined value that is lower than reverse withstand voltage of the rectifying element included in the rectifier, the impedance of the impedance changer as viewed from the rectifier is a value regarded as corresponding to a short circuit.

  • Patent number: 10651658
    Abstract: A foreign object detecting device includes first and second coils, the winding directions of which are the same, and a foreign object detecting circuit. The foreign object detecting circuit outputs a first detecting signal having a first predetermined waveform to a first terminal of the first coil and outputs a second detecting signal having a second predetermined waveform, which has the same polarity as the first predetermined waveform, to a third terminal of the second coil to cause magnetic fields generated from the first and second coils to repel each other. The foreign object detecting circuit measures an amount of change of the impedance value of the first or second coil which is caused by the presence of a foreign object. When the amount of change exceeds a predetermined value, the foreign object detecting circuit determines that there is a foreign object above the first or second coil.
