Abstract
The application of multilevel inverter is increased in industries there are different kinds of topology were implemented. The motive of this research work is to reduce the total harmonic distortion by using a reduced number of components. The topology is consisting of H-bridge cascaded with sub multilevel inverter. In this topology four asymmetrical DC sources are been used and eight power electronic switches are used to obtain thirty-one step. The PV (Photo Voltaic) module can be used for the asymmetric DC source. The implemented multi-level inverter topology can generate all voltage levels (positive, negative and zero). The multicarrier sinusoidal pulse width modulation technique is used generate pulse for each switch to obtain a pure sinusoidal waveform as output with low total harmonic distortion. The simulation results are obtained by using MATLAB Simulink. The experimental outputs are also demonstrated in hardware assemble set.
