Abstract: A wireless power transmission device comprises: a ground-side coil (13) for generating a magnetic field by current supplied from a power control device (7); a current transformer (23) for detecting the magnitude of an input from the power control device (7); a power supplying device-side control unit (6) for, based on a detection signal from the current transformer (23), controlling the current supplied from the power control device (7) to the ground-side coil (13); and a vehicle-side coil (15) for receiving power via the magnetic field coming from the ground-side coil (13). When detecting an input change having a predetermined value or more on the basis of the detection signal from the input detection unit (23), the power supplying device-side control unit (6) stops the current supplied to the ground-side coil (13).

Abstract: A coil for a non-contact power transmission system according to the present disclosure is used in a non-contact power transmission system to transmit electric power via a non-contact method. The coil includes a first coil in which a wire is wound around at a center of a core; and a second coil placed at an end of the core, and wound with the wire. Winding axes of the first and second coils are oriented in different directions.

Abstract: The present disclosure provides a non-contact charging apparatus including a power transmitting coil and a power receiving coil which face each other. At least one of the power transmitting coil or the power receiving coil includes a magnetic body and a coil wound around the magnetic body. The magnetic body has, on both end portions, exposed regions in which the wound coil is absent. One of the exposed regions that is on a face facing the power transmitting coil or the power receiving coil is larger than another one of the exposed regions that is on a face not facing the power transmitting coil or the power receiving coil.

Abstract: A non-contact charger aims to control transmitted power efficiently. The non-contact charger includes a transmitting coil, an inverter circuit, a receiving coil, and a transmitted power control circuit. The inverter circuit outputs the transmitted power to the transmitting coil. The receiving coil receives power as received power from the transmitting coil. The transmitted power control circuit drives the inverter circuit at a frequency higher than maximum received power frequencies at which the received power has one or two maximum values.

Abstract: Disclosed is a noncontact power transmission system including a power transmission device for transmitting power to a power receiving device in a noncontact manner. The power transmission device includes a cover covering a portion of an outline of the power transmission device where the power transmission device faces the power receiving device, a base covering another portion of the outline of the power transmission device where the power transmission device does not face the power receiving device, a magnetic body arranged in a space enclosed with the cover and the base, a coil bobbin covering the magnetic body partially or entirely, and a coil wire which is wound around the coil bobbin and which generates a magnetic flux upon receiving an alternating current. The coil bobbin includes a load support.
