Abstract
A method for actuating an AC/DC voltage converter is specified, which has a DC voltage output between which at least one series circuit of at least two capacitors and at least one series circuit of n switching elements-is arranged, where n≧4. A connecting point of the switching elements is connected to a connection of an AC voltage input between n/2 switching elements. Two diodes are connected in an antiparallel arrangement to the two switching elements lying closest to the connecting point. In addition, a connecting point of the capacitors is connected to a connecting point of the diodes. An output voltage at the DC voltage output and a potential of the connecting point of the capacitors or diodes are provided as controlled variables, an input current at the AC voltage input is provided as a manipulated variable and the switching elements are provided as an actuating element of a control loop. In addition, a controller for implementing the method and an AC/DC voltage converter containing such a controller are specified.
