  • Publication number: 20230411996
    Abstract: A system for transmitting electrical energy from an energy source to a consumer, e.g., for contactlessly transmitting energy to a mobile consumer, includes a first line conductor and a second line conductor. Each line conductor has, in a respective axial direction, an at least approximately rectangular cross-section, the long sides of which are longer than the broad sides. The axial directions of the line conductors extend at a right angle with respect to a vertical direction. The first and second line conductors intersect in an intersection region in which a holding device is arranged, and are arranged outside the holding device such that the long sides of the line conductor cross-sections are parallel to the vertical direction. The first and second line conductors are arranged in a central region of the holding device such that the long sides of the line conductor cross-sections are oriented at a right angle with respect to the vertical direction.

  • Publication number: 20230337352
    Abstract: A printed circuit board (PCB) includes a top side for receiving electrical components, a bottom side for receiving a heat sink, electrically conductive layers, and electrically insulating insulation layers. A main insulation layer is arranged between the top and bottom sides. The main insulation layer completely electrically insulates electrically conductive layers arranged between the main insulation layer and the top side from electrically conductive layers arranged between the main insulation layer and the bottom side. Upper plated through-holes extend from an outer insulation layer adjacent the top side into an inner insulation layer adjacent the main insulation layer. Lower plated through-holes extend from the bottom side into a lower insulation layer adjacent the main insulation layer. A circuit arrangement includes the printed circuit board, electrical components fitted to the top side and connected to the PCB, and heat sink(s) fitted to the bottom side and connected to the PCB.
