Title:
DEVICE FOR THE INDUCTIVE TRANSMISSION OF ELECTRICAL POWER
Document Type and Number:
WIPO Patent Application WO2003005380
Kind Code:
B1
Abstract:
The invention relates to a device for the inductive transmission of electrical power, comprising a power line which is situated on the primary side of said device and which consists of two wires which are guided in a parallel manner relative to each other. Power can be drawn from line by at least one mobile consumer, which is situated on the secondary side, by means of inductive coupling. Said device is provided with a data line which is situated on the primary side for the additional inductive transmission of data to and/or from the consumer. Said data line consists of two wires which are guided in a parallel manner relative to each other. Each of the data line wires is arranged adjacent to one of the two power line wires and in a manner that is symmetrical to a plane. The cross section of the conductor of the adjacent wire of the energy line is also symmetrical relative to the plane. The inductive coupling between the power line and the data line can be thus kept very low, and simultaneously enables the inductor, which is to be provided on the secondary side for the magnetic coupling with the data line, to be integrated into or mounted on the energy-transmitting consumer. The data line can be fixed to the power line or both lines can be integrated therewith in a common cable.
