20100013301 | ELECTRIC POWER SUPPLY SYSTEM - An electric power supply system mounted on a moving body, which supplies electric power from a plurality of direct-current power source devices to an alternating-current drive apparatus that functions as a drive source of the moving body. Each of the plurality of direct-current power source devices is connected to a corresponding inverter, which converts a direct-current output of the direct-current power source device into an alternating-current output, thereby forming one alternating-current output unit. Alternating-current wirings are used to make connection between each alternating-current output unit and the alternating-current drive apparatus and between respective alternating-current output units. Thereby, it is possible to keep electrical insulation between electric power supply wirings and a moving body with relative ease and also make connection between the direct-current power source devices in a simple and easy way. | 01-21-2010 |
