A coil assembly for wireless electrical power transmission includes a plurality of external connecting terminals, a power feeding coil, a resonant capacitor electrically connecting with the power feeding coil, and busbars each of which electrically connects between the external connecting terminals.

Coil assembly for wireless power transmission and power transmission system

A contactless power supply system is provided for supplying electric power to a vehicle in a contactless manner during traveling of the vehicle. The contactless power supply system includes a plurality of primary coils installed along a traveling direction in a road and a secondary coil mounted to the vehicle. Each of the primary coils is a single-phase coil with the secondary coil being a multi-phase coil, or is a multi-phase coil with the secondary coil being a single-phase coil.

Contactless power supply system and contactless power supply apparatus

A dynamic wireless power transfer system performs, through a plurality of primary coils installed along a traveling direction of a road and a secondary coil mounted in a vehicle, power transfer to the vehicle while the vehicle is traveling. The secondary coil is an M-phase coil including M coils, M denoting an integer which is two or higher. The M coils each include a coil end extending along a front-rear direction of the vehicle and a main coil portion extending along a width direction of the vehicle, the M coils each being configured such that a magnetic resistance of a magnetic path where a magnetic flux of the coil end passes is higher than a magnetic resistance of a magnetic path where a magnetic flux of the main coil portion passes.

Dynamic wireless power transfer system

A power supply apparatus includes a storage battery and supplies a voltage from the battery to an electric load. The power supply apparatus includes first and second energizing paths connected in parallel between the battery and the load, a first switch making the first energizing path conductive and interrupting the first energizing path, and a second switch making the second energizing path conductive and interrupting the second energizing path. The power supply apparatus includes a first drive circuit that operates when a voltage is supplied and drives the first switch, a second drive circuit that operates when a voltage is supplied and drives the second switch into a conductive state in a case where the first switch is driven into a conductive state by the first drive circuit, first and second supply paths respectively supplying a voltage to the first and second drive circuits.

Power supply apparatus

A power supply control apparatus is applied to a power supply system that includes an opening and closing unit that has a plurality of switches that are connected in series on an energization path over which energization from a voltage source is performed and a plurality of diodes that are respectively connected in parallel to the plurality of switches, in which the plurality of diodes include diodes that are arranged in opposite directions to each other. The power supply control apparatus includes a determining unit determining that an abnormal state has occurred in which a current is flowing to any of the plurality of diodes in a state in which the plurality of switches are turned off, and a control unit controlling the switch that is connected in parallel to the diode through which the current is flowing to an on-state, when the abnormal state is determined to have occurred.
