Abstract: PROBLEM TO BE SOLVED: To specify a method for operating a converter circuit, and reduce thereby a harmonic component in system voltages of an AC voltage system connected with the converter circuit. SOLUTION: In the converter circuit which has a converter 2 having a large number of drivable power semiconductor switches and has a three-phase AC voltage system 1, the drivable power semiconductor switches are driven by means of a drive signal S A formed from a control signal S R , and the control signal S R is formed by adjusting an H-th harmonic component i NH of system currents to a system current set point value i NHref . In order to reduce a harmonic component in the system voltages, the system current set point value i NHref is formed by adjusting an H-th harmonic component of system voltages to a predeterminable system voltage set point value u NHref , the control difference from the H-th harmonic component of the system voltages and the system voltage set point value u NHref being weighted by a system impedance y NH determined with respect to the H-th harmonic component.

Abstract: The method involves operating a converter circuit which has an inverter (2) with a variety of controllable power switches and is connected to a three-phase alternating current electric power (1). The current power being a H-th harmonic component of mains power (UNH) is formed of a predetermined power. An error signal is provided from the H-system harmonic component of mains power and the power is weighted with respect to the H-th harmonic component network impedance (yNH). An independent claim is included for device for carrying out the method.

Abstract: An invertor having a plurality of invertor bridges which operate in parallel and whose output voltages are summed. The invertor bridges are driven with pulse duration modulation according to an auxiliary control voltage. The auxiliary control voltages of the individual invertor bridges have a constant phase difference between one another. The output voltages of the bridges are summed by a center tap which is grounded by a ground connection. Effective suppression of the common-mode current distortion is achieved by having the switch arranged in the ground connection.
