Abstract

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 are formed as substantially congruent conductor tracks of a multi-level printed circuit board, which can be connected to one another and arranged vertically on a distribution printed circuit board. The number of metallization planes of the multi-level printed circuit board being greater than the number of metallization planes of the distribution printed circuit board.

Claims (16)

1. An energy supply device for explosion-proof electronic functional units, comprising:

at least one inductor connected to supply an associated functional unit with a high-frequency AC voltage;

at least one multi-level printed circuit board; and

a distribution printed circuit board,

wherein the at least one inductor is formed as a substantially congruent conductor track of the at least one multi-level printed circuit board, the conductor tracks are connected to one another on the at least one multi-level printed circuit board,

wherein the at least one multi-level printed circuit board is arranged vertically on a distribution printed circuit board, and

wherein a number of metallization planes of the at least one multi-level printed circuit board is greater than a number of metallization planes of the distribution printed circuit board.

2. The energy supply device of claim 1 , wherein the at least one multi-level printed circuit board includes a plurality of multi-level printed circuit boards, and each multi-level printed circuit board includes the conductor track of one of the at least one inductor.

3. The energy supply device of claim 1 , wherein each metallization plane of the at least one multi-level printed circuit board has at least one turn of the at least one inductor.

4. The energy supply device of claim 2 , wherein each metallization plane of the plurality of multi-level printed circuit boards has at least one turn of the at least one inductor.

5. The energy supply device of claim 1 , comprising:

mechanical fasteners,

wherein the at least one inductor is mechanically fastened to the distribution printed circuit board via the mechanical fasteners.

6. The energy supply device of claim 1 , comprising:

electrical contacts,

wherein the at least one inductor is electrically connected to the distribution printed circuit board via the electrical contacts.
