Abstract
In a system and method for operating a system, which includes a first inverter which feeds a first electric motor, and a second inverter which feeds a second electric motor, the DC-voltage side connection of the first inverter is connected to the DC-voltage side connection of a rectifier which is supplied from an electrical AC-voltage supply network, the DC-voltage side connection of the second inverter is connected to the DC-voltage side connection of the rectifier, in particular, the two DC-voltage side connections of the inverters are switched in parallel, and a controller is provided, in particular in the first inverter, which controls the current accepted and acquired by the first inverter at its DC-voltage side terminal toward a setpoint value in that the torque of the first electric motor fed by the first inverter is the controlled variable.
