Abstract: The invention relates to a magnetic core (1) of an electronic arrangement, comprising a center region (3), a base (4a), which is formed in the shape of a planar plate, and a cover (4b), wherein the center region (3) is arranged between the base (4a) and the cover (4b), wherein a through-opening (2) with a center line (X) is formed in the center region (3), wherein a first cross-sectional area (9) of the magnetic core (1) in a first section plane (6), which is parallel to the base (4a) and in which the center line (X) is located, is substantially equal to a second cross-sectional area (8) of the magnetic core (1) in a second section plane (7), which is perpendicular to the first section plane (6) and in which the center line (X) is located, and wherein the base (4a) and the cover (4b) protrude beyond the center region (3) in the direction of the center line (X) on at least two mutually opposing sides.

Abstract: The invention relates to an electrical filter element (1) for filtering alternating voltage interference. The electrical filter element (1) comprises two dielectric circuit board substrates (11, 12) having a magnetic core (13) arranged between the circuit board substrates. The magnetic core (13) has a material-free inner region (13a), in which electrical connection elements (21-24) are provided between the two dielectric circuit board substrates (11, 12). Furthermore, electrical connection elements (31, 32) can also be provided between the two dielectric circuit board substrates (11, 12) in an outer region of the magnetic core (13).

Abstract: A method for producing an electronic circuit device includes a step of providing a substrate and a step of processing a III-V-connection semiconductor circuit on a substrate top side of the substrate. The III-V-connection semiconductor circuit has at least one III-V-connection semiconductor component, a second III-V-connection semiconductor component, and an electrical conductor, which electrically conductively connects the first III-V connection semiconductor component and the second III-V connection semiconductor component. In an arranging step, a metal layer or a metallized interconnect device is arranged on a rear side of the substrate, opposite the substrate top side, as an electrical contact surface for refeeding a current for a power electronic circuit.

Abstract: The present invention provides optimized driving of an inverter device. The inverter of such an inverter device may alternatively be driven in two-level operation or in three-level operation. Through a suitable selection of the driving method, the semiconductor losses in the inverter may be minimized and the thermal loading of the components used may be controlled in a targeted manner. Using the provided operating method for an inverter, more efficient and more protective inverter operation is possible, even at low output voltages and highly inductive or capacitive loading.
