SELF-COMMUTATED INVERTER AND OPERATION OF SAME

The invention relates to a method for operating a self-commutated inverter (1), which is supplied from a direct voltage circuit (3) and comprises electronic switches (S1, S2, S3) for producing a three-phase output voltage and a three-phase output filter (5) which is connected downstream of the electronic switches (S1, S2, S3) and is coupled to the direct voltage circuit (3). The electronic switches (S1, S2, S3) are controlled in an open-loop manner by space-vector modulation, in which a zero-phase-sequence system voltage is controlled in a closed-loop manner by filter-input voltages of the output filter (5) on the basis of a target-voltage space vector (u[alpha], [beta]_s) of the space-vector modulation and filter input currents (i1_in, 12_in, i3_in) of the output filter (5) such that oscillations in a zero-phase-sequence system of the filter input currents (i1_in, 12_in, i3_in) are suppressed. 本发明涉及一种用于运行自换向逆变器(1)的方法，逆变器从直流电压电路(3)被馈电并且具有用于产生三相的输出电压的电子开关(S1、S2、S3)和连接在电子开关(S1、S2、S3)下游的耦合到直流电压电路(3)处的三相的输出滤波器(5)
