Abstract: An exemplary energy supply device for explosion-proof electronic functional units includes a plurality of inductors. The functional units are supplied from a high-frequency AC voltage that is individually output for each of the functional units via an inductor. In order to supply a multiplicity of functional units with little effort, the multi-level printed circuit board of each inductor is at least partially covered with a flat board of a magnetic material parallel to the plane of its conductor tracks.
