Abstract
A method and arrangement are disclosed for operating a converter circuit. Such a converter circuit has a converter unit having a multiplicity of drivable power semiconductor switches. The converter unit is connected to an electrical AC voltage supply system on the AC voltage side. The drivable power semiconductor switches are driven by means of a drive signal formed from reference voltages (u*Na, u*Nb, u*Nc). The reference voltages (u*Na, u*Nb, u*Nc) are formed from a periodic modulation index and from a periodic modulation angle.
