FIELD: electricity.
SUBSTANCE: in accordance with the invention, a subsystem (10) of a branch (T1, …, T6) of valves corresponding to a faulty branch (T1, …, T6) of valves, of a faulty phase module (100) is controlled so that its terminal voltage (UX21) is equal to zero, and therefore accordingly one subsystem (10) corresponding to this branch (T1, …, T6) of valves of the branch (T1, …, T6) of valves of each faulty phase module (100) is controlled so that their terminal voltages (UX21) are equal to zero. Thus a control method is produced to use redundancy in case of a fault of a multi-phase AC rectifier with distributed energy accumulators (9), at the same time the generated output voltages (UL10, UL20 and UL30) no longer contain a DC voltage component.
EFFECT: improved method of rectifier control, so that DC voltage components do not manifest themselves in case of a fault in output circuits.
