Abstract
The charging padis provided with a position detection controllerthat supplies position detection signals to position detection coils, and detects induction coilposition from echo signals output from the induction coil. The device housing a batteryis provided with a series capacitorconnected in series with the induction coil, a parallel capacitorconnected in parallel with the induction coil, and a switching circuit. When the position detection controlleris issuing position detection signals, the parallel capacitoris connected to the induction coil. When power is transmitted from the power supply coilto the induction coil, the parallel capacitoris not connected to the induction coiland induction coilAC is output to a rectifying circuitthrough the series capacitor
