A modular multilevel converter includes a plurality of sub-modules. Each of the sub modules has at least two electronic switching elements, an electrical energy storage device, two galvanic power terminals, an optical communication input () and an optical communication output. A plurality of the sub-modules is connected to a series circuit by way of their communication input and communication output.

Modular multilevel converter

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.
