A multilevel converter (10) includes a power supply assembly with a plurality of phases (U, V, W), and a power cell assembly with first power cells (12) and second power cells (12). The first power cells (12) and second power cells (12) have a same topology and a same current rating, and supply power to the plurality of phases (U, V, W) of the power supply assembly. Each phase of the plurality of phases (U, V, W) includes a first power cell (12) and a second power cell (12) of the power cell assembly, voltage ratings of the first power cells (12) and the second power cells (12) being different. Furthermore, a method for controlling a multilevel converter (10) and an electric drive system (1) comprising a multilevel converter (10) are disclosed.
