Recently, industry requires the use of static power converters for high voltages and high currents applications. So, it is necessary to use an inverter. Today inverters use high power switching transistors called IGBT's and MOSFETS. These inverters have problems in high power applications. A Stacked Multi-cell Converter (SMC) represents a new solution to the problem. A SMC is an inverter (DC-AC converter) for high voltage applications. Here the analysis of SMC at different levels which decreases the THD with increase in levels is discussed and shown. This topology called SMC (Stacked Multi-cell Converter) consists of a hybrid association of commutation cell making possible to share the voltage and current constraint on several switches and this converter is made up of by p cells and n stacks. This configuration allows to share the total voltage and current stresses among the 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. Then, it is possible to use conventional semiconductors to handle high output power. A closed loop control is proposed using MATLAB Fuzzy Logic Toolbox, to control the RMS voltage at the output.The application area for a SMC can be found in applications such as UPS, Switching Power Supplies, and motor driversread more
