POWER FEEDING SYSTEM AND ELECTRICAL POWERED VEHICLE

摘要

Power is supplied from a power supply device (200) to an electric vehicle (100) in a non-contact way by resonance of a primary self resonance coil (240) of the power supply device (200) and a secondary self resonance coil (110) of the electric vehicle (100) via an electromagnetic field. The power received by the secondary self resonance coil (110) is rectified by a rectifier (130) and voltage-converted by a DC/DC converter (140) for supply to an accumulation device (150). A vehicle ECU (180) controls the DC/DC converter (140) so that the voltage between the rectifier (130) and the DC/DC converter (140) is a target voltage.
