    Abstract: A busbar arrangement for making electrical contact with a semiconductor module includes at least two busbars overlapping in an overlap region and electrically insulated from one another. Each busbar includes a web having a connection element, with the webs of the busbars being arranged without an overlap. The webs are oriented such as to define a first axis which runs through the connection element of an associated one of the webs and a point of a transition of the web to the overlap region of the busbar arrangement, and which intersects a second axis which is formed by a connection between two connection elements of the webs at an angle between 0° and 45°. The busbar arrangement includes an insulating region to reduce or prevent a current in the web in a direction perpendicular to the second axis. The overlap region and the webs are each located in one plane.

    Abstract: The invention relates to a method and an actuation assembly (3) for actuating a MOSFET (1), in particular a MOSFET (1) based on a semiconductor with a wide band gap. According to the invention, a characteristic block is generated in which a change (ΔU1, ΔU2, ΔR1, ΔR2) in at least one actuation variable (U1, U2, R1, R2) for actuating the MOSFET (1) with respect to a reference actuation value of the actuation variable (U1, U2, R1, R2) is stored on the basis of at least one operating characteristic variable (U, T) which influences the switching behavior of the MOSFET (1), said change counteracting a change in the switching behavior as a result of the at least one operating characteristic variable (U, T). During the operation of the MOSFET (1), an actual value of the at least one operating characteristic variable (U, T) is ascertained, and the reference actuation value of the at least one actuation variable (U1, U2, R1, R2) is changed according to the characteristic block depending on the actual value of the at least one operating characteristic variable (U, T).

    Abstract: A modular power converter with wide-bandgap semiconductors, in particular SiC semiconductors. The modular power converter has at least two base units. The base units are connected together on the input side, and each base unit has an input circuit on the input side and an output circuit on the output side. The input circuit and the output circuit are each formed by the wide-bandgap semiconductors arranged in a B6-bridge circuit. An intermediate circuit capacitor is connected in parallel with the input circuit and the output circuit forming an intermediate circuit. The input circuits of the base units or a sub-quantity of the base units are arranged in a series circuit. At least one inductor is arranged between each pair of input circuits.

    Abstract: A converter arrangement includes a basic structure having a receptacle, a first electrical network including lines arranged on the basic structure, a plurality of first contacts arranged on the basic structure and movable via a first actuator from a first connection position into a first release position, and a converter assembly securable in the first release position as a unit in a fixed location in the receptacle of the basic structure and removable from the receptacle. The converter assembly is electrically connected to the lines of the first electrical network when the first contacts assume the first connection position, and electrically disconnected from the lines of the first network when the first contacts assume the first release position. The receptacle of the basic structure is immobile when the first contacts move from the first connection position into the first release position.
