Abstract: A contactless feeding pad includes a power-receiving side pad, a power-transmitting side pad, and an auxiliary pad. The power-transmitting side pad is different from the power-receiving side pad in size or shape and transmits electric power contactlessly to the power-receiving side pad while being situated oppositely to the power-receiving side pad. The auxiliary pad is installed between the power-transmitting side pad and the power-receiving side pad in close proximity to the power-transmitting side pad or the power-receiving side pad and forms a resonance circuit.

Abstract: A contactless power supply system includes: a power supply pad including a power supply core formed of a magnetic material, and a power supply coil that uses the power supply core as a magnetic path; and a filter circuit including an inductor coil, the filter circuit being connected to the power supply pad. The power supply pads to which the respective filter circuits are connected are brought into a face-to-face relation so that electric power is transmitted from one power supply pad to the other power supply pad in a contactless manner. An inductor coil of at least either one of the filter circuits is provided to the power supply core of the power supply pad to which the filter circuit is connected, and the inductor coil uses the power supply core as a magnetic path.

Abstract: In a moving-object power supply system, a control unit selects, as a power transmission segment, one of segments included in at least one power transmission section. The control unit supplies, through a power supply circuit, power to the power transmission segment to thereby generate a magnetic field through a power transmission coil of the power transmission segment. The control unit determines, based on an ascertained first electrical characteristic of the power transmission segment and an ascertained second electrical characteristic of at least one power non-transmission segment, whether there is a malfunction in each of the power transmission segment and the at least one power non-transmission segment.

Abstract: A non-contact power supply apparatus includes a transmission-side pad, a transmission-side resonant circuit, a reception-side pad, a reception-side resonant circuit, a power transmission circuit, a power reception circuit, and a control circuit. The control circuit controls an alternating-current voltage supplied to the transmission-side pad and an alternating-current voltage supplied to the power reception circuit, so that a power factor of the alternating current supplied from the power transmission circuit to the transmission-side pad connected to the transmission-side resonant circuit and direct-current power supplied from the power supply circuit to an on-board battery are respectively set to target values. As a result, change in power factor can be suppressed even when the coupling coefficient of the transmission-side pad and the reception-side pad changes, and predetermined electric power can be transmitted.

Abstract: A contactless power supply system for transferring power without contact between a primary side coil and a secondary side coil is provided. In the contactless power supply system, a manipulation unit manipulates a secondary side converter so that power outputted to a load is controlled to be a command value. The manipulation unit manipulates an input voltage of a primary side resonance circuit so that a current flowing in the primary side resonance circuit equals a product of a current flowing in the secondary side resonance circuit and a current coefficient. The current coefficient is defined as a square root of a specific value and the specific value is an equivalent resistance of the secondary side resonance circuit divided by an equivalent resistance of the primary side resonance circuit.
