The invention relates to a method for controlling a power converter comprising at least two phase modules, each of which is provided with an upper and a lower valve leg that is equipped with at least two serially connected bipolar subsystems, respectively. According to the invention, the switching actions in the two valve legs (T1, T2; T3, T4; T5, T6) of each phase module (100) of the multiphase power converter having distributed energy stores are performed at a freely selected interval (?T<SUB>Z</SUB>) rather than synchronously. The inventive control method for a multiphase power converter having distributed energy stores thus makes it possible to dynamically regulate valve leg currents (i<SUB>11</SUB>, i<SUB>12</SUB>, i<SUB>21</SUB>, i<SUB>31</SUB>, i<SUB>32</SUB>). |
