Power feeding system and electrical powered vehicle
Abstract:
Power feeding is performed in a non-contact manner from a power feeding device to an electrical powered vehicle by resonance of a primary self-resonant coil of the power feeding device and a secondary self-resonant coil of the electrical powered vehicle through an electromagnetic field. The electric power received by the secondary self-resonant coil is rectified by a rectifier, and voltage-converted by a DC/DC converter to be supplied to a power storage device. A vehicle ECU controls the DC/DC converter such that the voltage between the rectifier and the DC/DC converter attains a target voltage.
