FIELD: instrument making.
SUBSTANCE: present invention is related to control converter (1), containing multiple bridge arms (2), containing one or more switching cells (3), connected in series, at that each arm (2) bridge connects one of multiple inlets and one of multiple-output converter (1). Method includes stages for control of each switching cell (3) with respect to detection of faults; started one of the trigger elements (41) for short-circuiting leads of switching cells revealed in one of switching cells (3) failure is not accompanied by detection of faults in one of the switching cells (3), in particular, in the limits of the preset period of time.
EFFECT: technical result is elimination of errors when detecting a faulty cell.
