Abstract:
A device for the contactless transmission of energy from a primary current line, through which alternating current flows, to a number of secondary, resonant load circuits with at least one coil each of which draws energy from the electromagnetic field of the current line, the device comprising an auxiliary line running parallel to the current line and connected with the current line via several connecting points for conducting the current from a first connecting point via the auxiliary line to a second connecting point, an adjustable resistance in at least one section of the auxiliary line, between two connecting points, and a monitoring device for controlling said adjustable resistance in order to prevent blocking of the line by a disconnected consumer, the monitoring device monitoring the voltage on the adjustable resistance of at least one line section and generating control pulses for the adjustable resistance at specific changes in value.
