    Abstract: A semiconductor module arrangement includes a housing, a first semiconductor substrate arranged inside the housing, a second semiconductor substrate arranged inside the housing, a first plurality of controllable semiconductor elements, and a second plurality of controllable semiconductor elements. During operation of the semiconductor module arrangement, each controllable semiconductor element of the first plurality of controllable semiconductor elements generates switching losses and conduction losses, the switching losses being greater than the conduction losses. Further during operation of the semiconductor module arrangement, each controllable semiconductor element of the second plurality of controllable semiconductor elements generates switching losses and conduction losses, the conduction losses being greater than the switching losses. At least a first sub-group of the first plurality of controllable semiconductor elements is arranged on the first semiconductor substrate, and at least a first sub-group of the second plurality of controllable semiconductor elements is arranged on the second semiconductor substrate.

    Abstract: A power semiconductor arrangement includes a plurality of half-bridges arranged in parallel alongside one another by way of a longer longitudinal side of the half-bridges. An input load current terminal, an output load current terminal and a phase terminal are arranged on a top side of each of the half-bridges, the input load current terminals and the output load current terminals being arranged on an imaginary line that runs orthogonal to the longer longitudinal side of the half-bridges. First connection plates are connected to respective ones of the output load current terminals, and second connection plates are connected to respective ones of the input load current terminals. The first connection plates are arranged above the second connection plates. The first and the second connection plates are arranged in parallel with one another and electrically insulated from one another.

    Abstract: A drive circuit includes a first output node for connection to the control electrode of the semiconductor switch, a voltage supply circuit, and a first switching stage connected to the voltage supply and a second switching stage connected to the voltage supply. A first resistor network is connected between the first switching stage and the first output node. A second resistor network is connected between the second switching stage and the first output node. A control logic is designed to generate control signals for the guiding of the first switching stage and the second switching stage in such a way that in a first operating mode of the semiconductor switch the semiconductor switch is driven only via the first resistor network, and in a second operating mode of the semiconductor switch the semiconductor switch is driven only via the second resistor network or both resistor networks.
