Abstract
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 (T, T; T, T; T, T) of each phase module () of the multiphase power converter having distributed energy stores are performed at a freely selected interval (ΔTZ) 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, i, i, i, i).
