ABSTRACT:
A control device for a three-phase machine contains an inverter, which can be connected on the input side to a direct voltage source and on the output side to the three-phase machine. The control device further has a reactive power converter, which on the output side is terminated by a capacitor and on the input side is disposed electrically parallel to the inverter, namely on the input side of the inverter.
