In a system for an inductive energy transmission from a primary-conductor system, in particular a stationary primary conductor system, to a vehicle having a secondary winding, the secondary winding is inductively coupled with the primary-conductor system. The primary conductor is installed as a primary-conductor loop installed in elongated form, which has a feed conductor and a return conductor in a line section, in particular a return conductor that is installed parallel thereto, and the return conductor is electrically grounded in that at least one inductance is disposed between the return conductor and the electrical ground.

System for an inductive energy transmission from a primary-conductor system to a vehicle having a secondary winding

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.
