A method is specified for operation of a converter circuit, wherein the converter circuit has at least two phase modules (4), each phase module (4) has a first and a second sub-converter system (1, 2), and the sub--converter systems (1, 2) for each phase module (4) are connected in series with one another, each sub-converter system (1, 2) comprises a plurality of series-connected two-pole switching cells (3), and in which method the control signals (Si, S2) for the switching cells (3) are additionally formed from a damping signal (V d, U1, V d, U2), wherein the damping signal (V d, U1) is formed from a measured current (i1, i2) through the respective sub-converter system (1, 2) and from a predeterminable resistance value (R d), in order to attenuate undesirable currents in the sub-converter systems (1, 2).
