  "textContent": "A power electronics multilevel converter comprises one or more phase legs. Each respective phase leg of the one or more phase legs comprises a plurality of cells. Each respective cell of the plurality of cells comprises an alternating current (AC)/direct current (DC) converter, a closed-loop control and a DC/DC converter. The closed-loop control is configured to regulate the cell power transmitted by the AC/DC converter to a DC link of the respective cell in accordance with a cell power reference. The cell power reference depends on a cell voltage reference. The closed-loop control is further configured to adjust the cell voltage reference in dependence of a cell power reference deviation from an average power per cell. The average power per cell depends on the cell power references of the plurality of cells of all phase legs.",
