Various examples are directed to systems and methods for a multi-level inverter to convert direct current (DC) to alternating current (AC). The inverter may comprise first, second and third capacitors electrically coupled in series between a positive DC rail and a negative DC rail. A first pole switch bank of the inverter may comprise a plurality of first pole switches. A first pole may be electrically coupled to the first pole switch bank. A control circuit may comprise at least one processor that is programmed to alternately switch the first pole switch bank to a first state of the first pole switch bank in which the first pole is electrically coupled to the positive DC rail, a second state of the first pole switch bank in which the first pole is electrically coupled between the first capacitor and the second capacitor, a third state of the first pole switch bank in which the first pole is electrically coupled between the second capacitor and the third capacitor, a fourth state of the first pole switch bank in which the first pole is electrically coupled to the negative DC rail. |
