Multilevel Inverters are very important in the field of medium and high voltage applications. This paper presents the Stacked Multicell Converter which is derived topology of the conventional Flying Capacitor Multilevel Inverter topology. The Level Shifted Multicarrier Sinusoidal Pulse Width Modulation technique is used for the generation of firing signals for Stacked Multicell Converter (SMC). The Stacked Multicell Converter topology of Multilevel Inverter causes increase in the number of output voltage levels with less THD, natural self balancing of flying capacitors voltage, increase redundancy to obtained desired voltage level, reduction in the voltage ratings of capacitors and semiconductor losses. The proposed topology is simulated using MATLAB Software package and simulation results are presented to validate the effectiveness and advantages of the proposed Stacked Multicell Converter (SMC) topology.
