Harmonics Elimination in Multilevel Inverter with Two Unequal Voltage Batteries
نویسندگان
چکیده
Elimination of harmonics in a multilevel inverter with two unequal dc sources is considered. That is, for a given fundamental output voltage, our aim is to find the switching angles, that produce the fundamental while not generating specifically chosen harmonics. A procedure is given to find all sets of switching angles for which the fundamental is produced while lower order harmonics are eliminated. This is done by first converting the transcendental equations that specify the elimination of the harmonics into an equivalent set of polynomial equations. Then, using the mathematical theory of resultants, solution to this equivalent problem is found.
