Abstract
Several DC link converters are interconnected at first and second terminals. Each DC link converter has an input-side rectifier connected to a power supply and an output-side inverter connected to a load, and a DC link with a DC link capacitor. Potentials of the DC link capacitor are connected via first and second lines respective first and second terminals. A switching element and a parallel-connected diode are arranged in at least one of the lines. A control device controls the switching element depending on the DC link voltage and/or as the current flowing through the respective line, allowing the DC link capacitor to be charged, but not discharged via the diode when the switching element is non-conducting, and to be at least discharged when the switching element is conducting. An inductor is arranged in at least one of the lines, and a flyback diode is connected between the lines.
