Abstract:
A method is provided for operating a frequency converter, which is designed to drive a three-phase motor, wherein the frequency converter has three half-bridges each having at least two switches. The method includes the following steps: generating three phase voltages for the three-phase motor by a pulse width modulation, wherein, for the pulse width modulation, various switching patterns of the switches are activated, wherein specific star point voltages ensue for various groups of switching patterns; and in at least one operating state of the frequency converter, within a respective period of the pulse width modulation, activating only those switching patterns in which an identical star point voltage ensues.

Claim (Index 7):
The method as claimed in  claim 6 , wherein\n the three half-bridges each have a first state during which an output of the respective half-bridge is connected to a positive DC link potential, said state being denoted by 1, and each have a second state during which an output of the respective half-bridge is connected to a negative DC link potential, said state being denoted by 0, wherein, in the at least one operating state, within a respective period of the pulse width modulation, only the following switching patterns are activated: either (100, 010, 001) or (011, 101, 110).
