| Abstract |
This paper presents a fast and effective optimal solution of harmonic elimination of multilevel inverters with unbalanced
DC sources using fuzzy linear programming (FLP). A set of non-linear mathematical models containing a description of the general output waveform of cascaded H-bridge multilevel inverters with unbalanced DC sources, will be formulated. An objective function will be employed to obtain an optimal solution for a set of switching instances to eliminate undesired
harmonics. The solution algorithm will also control the output voltage level at the desired fundamental component.
FLP is used to obtain an accurate and fast solution to minimize the linearized objective function and identify the desired set of switching angles. The proposed fuzzy linear programming is tested both in simulation and experimentally, for different cases of multilevel inverters to verify the accuracy of the results. |
