Abstract The invention relates to a method for operating a converter (1), wherein the converter (1) comprises a plurality of bridge branches (2) having one or more switching cells (3) connected in series, wherein each bridge branch (2) connects one of a plurality of inputs to one of a plurality of outputs of the converter (1), having the following steps: - each of the switching cells (3) is monitored in order to determine a fault; and - if a fault is identified in one of the switching cells (3), one of the triggering elements (41) for short-circuiting switching cell connections is triggered if the fault identified in the switching cell (3) is not followed by identification of a fault in a further one of the switching cells (3), in particular within a predetermined period of time.
