NON-CONTACT POWER SUPPLY DEVICE

WIPO Patent Application WO/2014/038017

A1

A non-contact power supply device (1) of the present invention comprises: non-contact power supply elements (41, 42) and a high-frequency power supply circuit (5) both provided in a fixed unit (2); and a non-contact power receiving elements (61, 62) and a power receiving circuit (7) both provided in a movable unit (3), said power receiving circuit (7) converting the high-frequency power received by the non-contact power receiving elements (61, 62) and supplying the converted high-frequency power to a power load (L) in the movable unit (3). In the non-contact power supply device (1), the power load (L) selectively consumes or generates power. The non-contact power supply device (1) further comprises: a regeneration reverse-transmission circuit for reversely transmitting regenerative power generated by the power load (L) from the non-contact power receiving elements (61, 62) to the fixed unit (2) via the non-contact power supply elements (41, 42) in a non-contact fashion; and an electricity storage element (52) provided in the fixed unit (2) and storing the reversely transmitted regenerative power. This enables the regenerative power obtained by the power load (L) in the movable unit (3) to be effectively used and the weight and size of the movable unit (3) to be reduced in comparison with conventional techniques.
