Abstract
A method for controlling a modular multi-level converter including a multiplicity of modules having at least one energy storage unit and a plurality of controllable switches. The modular multi-level converter is controlled by pulse-width-modulated control signals. A respective control signal is generated on the basis of a respective carrier signal having a phase shift relative to the respective module, and on the basis of at least one reference signal. As a result of a comparison, based on a size comparison, of a signal profile of the respective carrier signal with the at least one reference signal, a connection time of the at least one energy storage unit of the respective module to a load current is triggered. The signal profile of the respective carrier signal is modified by at least one change within three degrees of freedom.
