Abstract
The invention relates to a method for controlling a multi-phase power converter having at least two phase modules () comprising valve branches (T, . . . , T) having bipolar subsystems () connected in series, at low output frequencies (f). According to the invention, a target value (u(t), . . . , u(t)) of a valve branch voltage overlaps a common-mode voltage (uCM(t)) such that a sum of two valve branch voltages (u(t), U(t) or U(t), U(t) or U(t), U(t)) of each phase module () equals an intermediate circuit voltage (Ud) of said multi-phase power converter. In this manner a known converter having a triphase power converter comprising distributed energy accumulators on the grid and load side, or merely on the load side, may be utilized as a drive converter, which may start up from the idle state.
