A Generalised Cascaded Multilevel Inverter Using Series Connection of Submultilevel Inverter

Abhay Kumar, Anurag Anurag, Ashok Kumar Mahto, Ashok Kumar


Application of multilevel inverters for higher power purposes in industries has become more popular. This is partly because of high-quality output waveform of multilevel inverters in comparison with two level inverter. In this paper, initially a new topology for sub multilevel inverter is proposed and then series connection of the sub multilevel inverters is proposed as a generalized multilevel inverter. The proposed multilevel inverter uses reduced number of switching devices. The validity of the proposed multilevel inverter is verified with computer simulations using matlab, simulink.
