Patent ID: 8848807

Claim:
An apparatus for the transmission of electrical energy and data between a primary side and a secondary side, comprising: at least one transferring unit provided between the primary side and the secondary side; at least one first data channel and at least a second data channel on the secondary side, each of which has at least one address of its own; at least one frequency control unit on the primary side, which is embodied in such a manner that said frequency control unit sets a working frequency of said at least one transferring unit corresponding to data to be transferred and corresponding to addressing of said at least one first data channel and said at least one second data channel respectively; and at least one load setting unit on the secondary side, which is embodied in such a manner that said at least one load setting unit sets the electrical load, which lies on the secondary side on said at least one transferring unit, corresponding to data to be transferred and corresponding to the address of said at least one first data channel and at least one second data channel respectively; wherein in the data communication the address of the data channel for which the data are intended or from which the data come is transmitted between the primary side and the secondary side; and wherein said at least one first data channel is embodied in such a manner that it transmits data via said at least one transferring unit only after a preceding addressing from the primary side via said at least one transferring unit.
