Abstract

Multilevel inverter plays an important role in the field of modern power electronics and is widely being used for many high voltage and high power industrial and commercial applications. The objective of this paper is to design and simulate the modified asymmetric multilevel inverter topology with reduced number of switches. The proposed inverter topology synthesizes 21-level output voltage during symmetric operation using three DC voltage sources and twelve switches 8 main switches and 4 auxiliary switches. The different methods of calculating the switching angles are presented in this paper. The MATLAB/Simulink software is used to simulate the proposed inverter. The performance of the proposed inverter is analyzed and the corresponding simulation results are presented in this paper.
