As the field of power electronics is growing new topologies of inverters have been implemented to satisfy the requirements. This paper initially presents a symmetrical cascaded multilevel inverter and then presents a new proposed symmetrical cascaded multilevel inverter (9 levels) controlled by fuzzy logic. In this proposed method the number of switches is reduced from 16 to 10 by using two low frequency switches. In this method the THD is reduced and a satisfactory RMS output value can be obtained. In this paper RMS output value is controlled using MATLAB/fuzzy logic toolbox. All the Circuits are simulated using MATLAB/ SIMULINK and the results are presented to show the effectiveness. © 2014 IFAC.

Control of Symmetrical Cascaded Multicell Inverter using Fuzzy Logic

IFAC Proceedings Volumes

Reduced Voltage Source Multicell Converters are one of the best alternative for Capacitor Multicell Converter, as the former uses only a single voltage source as compared to the later which uses two voltage sources for a single phase converter. In this paper three different levels (i.e., 5 level, 7 level and 9 level) of reduced voltage source multicell converters are analyzed by taking THD as an analyzing parameter, from the analysis it can be inferred that the THD decreases with increase in the number of levels. Suitable fuzzy controllers are designed for the different levels of reduced voltage source multicell converters to control the RMS output voltage. The performance of the fuzzy controllers for the different levels of reduced voltage source multicell converters are analyzed. © 2016 IEEE.
