Multilevel inverter plays an important role in the field of modern power electronics. The objective of this paper is to design and
simulate the modified symmetric multilevel inverter topology with reduced number of switches. The proposed inverter topology
able to synthesize nine level output voltage during symmetric operation using four dc voltage sources and eight main switches.
The different methods of calculating the switching angles were discussed in this paper. The MATLAB/Simulink software is used
to simulate the proposed inverter. The performance of the proposed nine level inverter is analysed and the corresponding
simulation and hardware results are presented in this paper. The experimental results justify the simulated response and the
practical feasibility of the proposed nine level inverter topology for use in the field.
