摘要： An inverter device for providing a drive voltage for a drive motor (110) for an electric vehicle (100). The inverter device (108) has a battery interface (130) for connecting the inverter device (108) to a vehicle battery (104) of the electric vehicle (100), a drive interface (116) for connecting the inverter device (108) to the drive motor (110), and an auxiliary interface (118) for connecting the inverter device (108) to an auxiliary drive (112). The inverter device (108) further has an inverter (140) to convert a DC voltage applied to the battery interface (130) into an AC voltage and to provide the latter either at the drive interface (116) or at the auxiliary interface (118) using a control signal (132).

摘要： A power distribution includes first and second inputs, first and second outputs, and a third output configured to connect to a low-voltage vehicle power supply, a high-voltage distributor is connected to the first input and forms the connection between the energy storage and further components of the power distribution. A controller monitors at least the high-voltage distributor and can control components of the power distribution. At least one inverter is arranged in the current path between the high-voltage distributor and at least one of the contacts for the first output, the second output or the second input, a first converter is arranged between the high-voltage distributor and the third output and converts a DC voltage provided by the high-voltage distributor to a lower DC voltage.

摘要： A network of an electric vehicle has an energy supply interface, an inverter, an energization interface and a soft starter. The inverter has a first inverter connection configured to connect the inverter to the energy supply interface and a second inverter connection configured to connect the inverter to the energization interface and the soft starter. The inverter is configured to convert a DC voltage applied to the first inverter connection to an AC voltage and to supply same at the second inverter connection. The soft starter is configured to reduce an input voltage applied to the first soft starter connection and to supply the operating voltage, which is reduced compared to the input voltage, at the second soft starter connection.
