Beschreibung
Zusammenfassung:	The invention relates to an energy supply unit for transmitting auxiliary energy to an electrical device, especially a control circuit in a medium or high voltage installation. Said energy supply unit comprises a primary coil which is at least indirectl y connected to an energy source; a secondary coil which is at least indirectly connected to the control circuit; and an insulating section formed between the primary coil and the secondary coil. The auxiliary energy is transmitted via said insulating section by means of a magnetic alternating field. The aim of the invention is to produce an energy supply unit having a simple and cost-effective structure and producing low leakage inductance and high coupling inductance. In order to achieve this, the energy supply unit comprises a first carrier plate; a primary coil embodied as a flat coil situated on the first carrier plate; a second carrier plate; and a secondary coil embodied as a flat coil situated on the second carrier plate. The insulating section is embodied as an interferric space formed between the primary coil and the secondary coil.
