Abstract
An inspecting apparatus is for a noncontact power transfer system that transfers electric power from a transmitting unit to a receiving device in a noncontact manner. The inspecting apparatus includes a coupling capacitance varying unit configured to vary at least one of a first coupling capacitance formed between a transmitting-side passive electrode and a receiving-side passive electrode and a second coupling capacitance formed between a transmitting-side active electrode and a receiving-side active electrode when the receiving device is placed on the transmitting unit, and a control unit configured to monitor an alternating-current voltage generated between the receiving-side passive electrode and the receiving-side active electrode of the receiving device or a direct-current voltage obtained through conversion by a rectifying circuit.
