  • the received power is well below one watt, mostly in the 10 OmW range. This is due to the fact that the diode-based rectifiers used for this purpose have limitations with regard to current and voltage peaks as well as heat dissipation. For this reason, only the supply of a consumer with low power consumption is possible.
  • the object of the invention is to provide a method and an arrangement which overcome the disadvantages of the aforementioned solutions.
  • This object is achieved by an arrangement for galvanically separated energy transmission according to the features of claim 1 and by a method for galvanically isolated energy transmission according to the features of claim 12.
  • the arrangement according to the invention for galvanically separated energy transmission with voltages in the high-voltage range is designed in such a way that the energy transmission takes place through a dielectric waveguide. This ensures that the received power, that is the pre-consumer ⁇ scheduled performance, namely up to 10 watts or higher, is significantly higher than the prior art allows.

  • the insulating shield device is arranged such that a space between the dielectric -Create Wel ⁇ lenleiter and the shield means the distance exists. This will be particularly advantageous if the dielectric constant of the shielding device is greater than or equal to the dielectric constant of the dielectric waveguide.

  • the waveguide is formed from at least one square and / or round, rod-shaped body. This is advantageous, for example, since it is well researched and thus easy to model with regard to optimum function, in particular transmission values.
  • the dielectric waveguide is formed from materials, in particular aluminum oxide or Teflon, with a dielectric constant> 1.
  • the energy is transmitted via a dielectric waveguide.
  • the inventive method sets by its features the basis for the development of the advantages of the erfindungsge ⁇ Permitted arrangement and its developments.

  • Example ⁇ materials, with which this development of the invention is achieved, are aluminum oxide or Teflon.
  • the dielectric waveguide DIELEKTRI SCHER_WELLENLEI ER shown in the exemplary embodiment has the property of supplying not only one consumer ENDGER, but several, since, according to the invention, power can already be coupled out before the end of the conductor and fed to another consumer.
