A Comparison of 5 Level Multilevel Inverter Topologies

Now days, multilevel inverters are required for high power applications. The multilevel inverters are not only achieves high power ratings, but also use the renewable energy sources. Renewable energy sources like photovoltaic, wind and fuel cells can easily used to supply to inverter system. This paper deals with the comparative study of other topology of multilevel inverter and traditional multilevel inverter basically cascaded H-bridge inverter topology. The proposed topology reduced the number of switches and THD compare to the traditional multilevel inverter.
