ABSTRACT:
In a method for controlling a rectifier and an inverter, which are connected together by a direct current circuit, a measuring direct current voltage and respectively, a measuring direct current are measured at at least one measuring point of the direct current circuit and are transmitted to a direct current control for controlling the rectifier and/or an inverter control for controlling the inverter. The direct current control controls the rectifier in such a manner that a total of a difference direct current voltage and a differential direct current is minimal and the inverter control of the inverter is controlled in such a manner that the difference between the differential direct current of the differential direct current voltage is minimal. The method is reliable and is economical. Accordingly, the desired flow of the direct current control and the desired flow of the inverter control are identical.
