Abstract: A converter has module devices each with a series connection of at least two partial modules being electrically connected in series. A central device is configured to switch module control devices, in which a sum of the transmitted voltage values or the transmitted sum value reaches a predefined voltage threshold, into a second charging phase of a charging operation by transmitting a first voltage specification relating to switched-off partial modules and a second voltage specification relating to switched-on partial modules to the module control devices. The module devices are configured to meet the first and second voltage specifications by setting none, one or more of the communication-capable partial modules thereof into a switched-on operating state and none, one or more of the other communication-capable partial modules thereof into a switched-off operating state, and to continue the charging of the energy stores which are in the switched-on and blocked operating state.
