Lower prices of power switches and new semiconductor technologies, as well as the current demand on high-performance inverters required by renewable energy systems, have extended the applications of multilevel converters. This paper presents the important topologies of multilevel inverter like diode-clamped (neutral-point clamped), and cascaded H-bridge with separate dc sources. This paper also presents the most relevant sinusoidal pulse width modulation method for this family. Simulation and comparison of NPC and cascaded H-bridge multilevel inverter with SPWM switching is done using MATLAB/SIMULINK
