Multilevel inverters supplied from equal and constant
dc sources almost dont exist in practical applications. The variation
of the dc sources affects the values of the switching angles required
for each specific harmonic profile, as well as increases the difficulty
of the harmonic eliminations equations. This paper presents an
extremely fast optimal solution of harmonic elimination of multilevel
inverters with nonequal dc sources using Tanaka&039;s fuzzy linear
regression formulation. A set of mathematical equations describing
the general output waveform of the multilevel inverter with nonequal
dc sources is formulated. Fuzzy linear regression is then
employed to compute the optimal solution set of switching angles.
