Abstract: A converter configuration has at least one series circuit with at least two series-connected sub-modules which in each case have at least one switch and are installed in each case at a predefined electrical installation position the converter configuration. The converter configuration further has a central unit connected to the sub-modules to control the sub-modules. The sub-modules in each case have a memory in which an identifier, in particular a serial number, uniquely identifying the respective sub-module is stored. The sub-modules in each case have a control device which can forward the stored identifier to the central unit via a communication connection connecting the respective sub-module and the central unit.
