Abstract
A method and a device for non-contact energy transmission from one or more medium-frequency current sources, whose medium frequencies may have deviations around f, to one or more moving consumers via one or more transmission lines and from or via transformer heads, allocated to the moving consumers, having one or more downstream matching controllers for adjusting the power received from the transmission lines. The currents fed into a matching controller are brought together with the aid of a single switch, depending upon the power demand of the consumers connected to the matching controller. The switching frequency of the switch is selected as a fixed value from a 10%-wide tolerance band around 1/f. The output voltages of a plurality of matching controllers are able to be parallel-connected via diodes for supplying a consumer.
