“…Therefore a mathematical model is not easily obtained and it can be complex. Moreover, multiple commutation states can be generated in order to achieve a particular state [14]. Hence fuzzy logic can be used to control the output of such kind of inverters, since this technique can capture vague information.…”

This paper provides the analysis of Multicell converter at different levels which decreases the THD with increase in levels. This topology called SMC (Stacked Multicell Converter) consists of a hybrid association of commutation cell making possible to share the voltage constraint on several switches, and also to improve the output waveforms of the converter in terms of number of levels and switching frequency. PWM technique is used to control the rms voltage at the output. A closed loop control is proposed using MATLAB Fuzzy Logic Toolbox, to control the rms voltage at the output. A complete fuzzy inference process to control the converter is shown. The Fuzzy Controller for 3x2 and 5x2 multicell converter is compared and it has been found that 5x2 multcell converter has good voltage constraint sharing feature than its 3x2 counterpart with reduced number of switches.

This paper presents a single-phase seven-level stack multicell converter (SMC) which provides a viable solution for multilevel converter. Conventional cascaded multilevel inverter (MLI) removes the drawbacks of clamping diodes and clamping capacitors topologies. However, in a cascaded MLI number of voltage source and power switches increases as the number of level increases. The main advantage of single-phase SMC converter is only two DC sources are needed for any number of levels. Level shifting SPWM technique has been incorporated to achieve gate pulses, in which carrier wave of 20kHz is compared with 50Hz sinusoidal reference wave at a modulation index of 1 and 0.9. Total harmonic distortion (THD) for SMC converter is achieved at 1.55% and 5.26% with and without filter respectively. The seven-level SMC topology is simulated in MATLAB/SIMULINK and simulation results are provided to verify the performance
