A protection configuration for converter means which comprise a plurality of controllable switches, the protection configuration comprising a protection circuit coupled to the alternating voltage side of the converter means, which protection circuit comprises at least one protective switch configured to short-circuit the alternating voltage side of the converter means, wherein the protection configuration, in predetermined failure situations, is configured to close the protective switch and thus to short-circuit the alternating voltage side of the converter means. After the failure situation has cleared up, the protection configuration is configured to short-circuit the alternating voltage side of the converter means by means of the controllable switches to enhance commutation of the protective switch.
