Claim:
1. An electrical system, comprising: an electrical converter comprising a plurality of semiconductor switches, wherein the electrical converter is adapted for generating a two-level or multi-level output voltage from an input voltage by switching the plurality of semiconductor switches, and a controller; wherein the controller executes a method for controlling the electrical converter comprising: receiving a reference electrical quantity (i determining a sequence of future electrical quantities of the electrical converter from the actual electrical quantity; determining a maximal cost value based on the sequence of future electrical quantities; iteratively determining an optimal switching sequence for the electrical converter, wherein a switching sequence includes a sequence of future switching states for the semiconductor switches of the electrical converter; and selecting the first switching state of the optimal switching sequence as a next switching state (u) to be applied to the semiconductor switches of the electrical converter, wherein the optimal switching sequence is iteratively determined by: an electrical load supplied by the electrical converter.
