Abstract
A method for switching control of a multi-level converter. The multi-level converter has a plurality of modules. A total switching state is formed from respective module switching states of the plurality of modules by the switching control. A current state of charge of all energy stores of the multi-level converter is provided continuously to the switching control. The switching control is divided into an offline part and an online part, wherein, in the offline part, a plurality of offline switching tables is calculated by way of optimizers in a continuous sequence and, for calculation of a respective offline switching table of the plurality of offline switching tables, a respective cost function is minimized according to at least one predefined offline optimization criterion for evaluating the total switching state. In the online part, an online switching table is selected from the plurality of offline switching tables in a continuous sequence.
