<P>PROBLEM TO BE SOLVED: To provide a method for operation of a converter circuit by which undesirable current variation and distortion in the converter circuit are actively attenuated. <P>SOLUTION: The converter circuit has at least two phase modules 4, where each of the phase modules 4 has first and second sub-converter systems 1, 2, and the sub-converter systems 1, 2 for each of the phase modules 4 are connected in series with one another. Each of the sub-converter systems 1, 2 includes a plurality of series-connected two-pole switching cells 3. The control signals S1, S2 for the switching cells 3 are additionally formed from damping signals. The damping signals are formed from measured currents i1, i2 through the respective sub-converter systems 1, 2 and from a predeterminable resistance value, in order to attenuate undesirable currents in the sub-converter systems 1, 2. <P>COPYRIGHT: (C)2011,JPO&INPIT |
