摘要

The system has a load i.e. resonance load (1), supplied by a secondary winding, where the secondary winding is inductively coupled to a primary conductor system, by a transformer, into which an alternating current of a feed-in (2) is stamped. A value of a state variable of the load is controlled by frequency of current and/or voltage fed to the load. The state variable is a relative velocity between the secondary winding and primary conductor system. The state variable is a relative velocity working direction between the secondary winding and primary conductor system.
