Title:
Non-contact electric supply device
Document Type and Number:
Japanese Patent JP6076355
Kind Code:
B2
Abstract:
The present invention of a contactless electric power supply device 1 comprises: a contactless electric power supply element 41 and a high-frequency power source circuit 5 provided on a fixed section 2, a contactless electric power reception element 6 and an electric power reception circuit 7 that supplies electric power to current consumer L on a movable section 3 which are provided on the movable section 3; and which further comprises a contactless transmitting element (integrated with 6) electrically connected to a contactless electric power reception element 6 provided on the movable section 3, a contactless reception element 42 that receives an electric signal related to the operating condition of current consumer L in a contactless manner from the facing and separated contactless transmitting element provided on the fixed section 2, and a detection circuit 8 that detects the operating condition of current consumer L based on the electric signal Sgnl from a contactless reception element 42 provided on the fixed section 2. From this, the operating stability of the current consumer L on the movable section 3 is higher while simplifying the electric circuit on the movable section 3 side, and the movable section 3 can be smaller and lighter reducing the supplied electric power and lowering equipment costs.
