摘要： A power supply system having a plurality of power systems is provided with a power output section in each of the power systems, an electrical load in each of the power systems, operating from power supplied by the power output section, main paths that connect the power output sections of adjacent ones of the power systems, an inter-system switch that establishes a conducting condition between the adjacent power systems by being turned on and establishes a disconnected condition between the adjacent power systems by being turned off, and an intra-system switch in each of the power systems, which is disposed on the main path between the power output section and the inter-system switch, and which establishes a conducting condition between the power output section and the electrical load by being turned on and establishes a disconnected condition between the power output section and the electrical load by being turned off.

摘要： 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.

摘要： 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.
