Abstract
The invention relates to a method for controlling a power converter having at least two phase modules, which each have an upper and a lower valve branch, each having at least three series-connected two-pole subsystems, in the event of failure of at least one subsystem of a valve branch of a phase module. According to the invention, the valve branch (T, T) with the failed subsystem () is determined, and in each case a subsystem () of a valve branch (T, T), which corresponds to the faulty valve branch (T, T), of any fault-free phase module () is driven such that its terminal voltages (UX) are in each case zero. A polyphase power converter with distributed energy stores () is therefore operated with redundancy.
