Claim 9:
10. A method of controlling a multi-level inverter, comprising:
receiving a reference voltage vector and an angle;
identifying a sector among sectors of a multi-level inverter including at least two levels, yielding an identified sector;
identifying a region among regions of the multi-level inverter based on the reference voltage vector and the angle, yielding an identified region;
selecting a switching sequence and turn-on time values based on the identified region; and
generating pulse width modulation (PWM) switching signals for the regions of the multi-level inverter and the sectors of the multi-level inverter based on the turn-on time values and the switching sequence,
wherein each of the regions includes a same number of the sectors.
