Abstract: A multilevel power converter is provided. A first cell comprises a first switch and a second switch connectable to a load via a first terminal and connected in series on opposite poles of a DC source. A second cell comprises a third switch and a fourth switch connectable to the load via a second terminal and connected in series on opposite poles of a DC capacitor. An intermediate cell connects the first and second cells and comprises a fifth switch connected to positive poles of the source and the capacitor, a sixth switch connected to negative poles of the source and the capacitor, a seventh switch connected to the positive pole of the source and to the negative pole of the capacitor, and an eighth switch connected to the negative pole of the source and to the positive pole of the capacitor.
