  • Energy supply device for explosion-proof electronic functional units
    Patent number: 9396864
    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.
    Type: Grant
    Filed: October 1, 2014
    Date of Patent: July 19, 2016
    Assignee: ABB Technology AG

  • ENERGY SUPPLY DEVICE FOR EXPLOSION-PROOF ELECTRONIC FUNCTIONAL UNITS
    Publication number: 20150123472
    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.
