ELECTRIC POWER FEEDING SYSTEM

摘要

Provided is an electric power feeding system, which is mounted on a mobile unit for feeding an electric power to a drive device (4) to function as a drive source of the mobile unit. The system comprises a first power source device (40) for generating an electric power and feeding it to the drive device (4), a second power source device (50) disposed separately of the first power source device (40) for feeding an electric power to the drive device (4), and a system insulating-type converter (30) interposed between an electric power feeding unit (PS) including at least one of the first power source device (40) and the second power source device (50) and a mobile unit driving unit (VD) including the drive device (4), for retaining the insulation inbetween while transmitting the electric power from the electric power feeding unit (PS) to the mobile unit driving unit (VD). This makes it compatible to raise the voltage of the power feed to the drive device and to retain the insulation.
