| Zusammenfassung: | An exemplary energy supply device for explosion-proof electronic functional units supplies each functional unit with a high-frequency AC voltage via an inductor. The inductors (1) are formed as substantially congruent conductor tracks of a multi-level printed circuit board (3), which can be connected to one another and arranged vertically on a distribution printed circuit board (4). The number of metallization planes of the multi-level printed circuit board (3) being greater than the number of metallization planes of the distribution printed circuit board (4). |
