An Experimental Analysis of Seven Level Cascaded H-Bridge Multilevel inverter for Harmonic Minimization By K.Mahendran (original) (raw)

This research on cascade H-Bridge multilevel inverter in these days for various sectors goes on rapidly due to its systematic operation. This paper proposes a harmonic minimization in distribution network by using power converter. This project deals simulation and experimentation of 7-level inverter. It presents 7-level inverter with harmonics reduction along with the reduction in number of switches. The percentage (%) total harmonic distortion is calculated for 7-level inverter. A standard cascade multilevel inverter requires n DC sources for 2n + 1 level. The functionality verification of the 7-level inverter is done using MATLAB and HARDWARE. The result of simulation is verified by experimentation. The harmonic components of the output voltage and switching losses can be diminished considerably.
