The Normal voltage balancing property of capacitor voltage has an attractive choice of an flying capacitor converters. The study of H-bridge flying capacitor converter with 5, 7 and 9 levels are carried out and to increase the voltage levels falls the Total Harmonic Distortion. By using phase shifted carrier pulse width modulation technique (PSCPWM) the root mean square output voltage is controlled. For effective output voltage control, fuzzy controller is used. Fuzzy controllers are designed for the different voltage levels of H-bridge flying capacitor multilevel converter to control the Root Mean Square (RMS) output voltage. The Performances of the fuzzy controllers with multilevel converters of H-bridge flying capacitor for different levels are studied. © Springer Nature Singapore Pte Ltd. 2017.

Analysis of Fuzzy Controller for H-bridge Flying Capacitor Multilevel Converter

Advances in Intelligent Systems and Computing Proceedings of Sixth International Conference on Soft Computing for Problem Solving

This chapter presents the experiment of symmetrical cascaded switched-diode multilevel inverter (SCSD MLI) with fuzzy controller for a different number of levels. The objective of this topology is to reduce the number of power semiconductor switches along with its gate driver circuits as the number of level increases; therefore, the complexity of the circuit and installation cost of the converter are reduced when compared with the conventional cascaded multilevel inverter and cascaded half-bridge multilevel inverter. In this document, seven-, nine-, eleven-level SCSD MLIs are analyzed with simulation results which describe the total harmonic distortion reduction with the increment in number of levels. For this circuit topology, phase disposition pulse-width modulation technique is developed to regulate the RMS output voltage of inverter. In order to maintain the RMS output voltage, appropriate fuzzy controllers are constructed. MATLAB/SIMULINK simulation results of seven-level, nine-level, and eleven-level are presented to justify the performance of the suggested topology. © Springer Nature Singapore Pte Ltd. 2019

Symmetrical Cascaded Switched-Diode Multilevel Inverter with Fuzzy Controller

Multi-level converters have gained a reputation in both Medium-Voltage and Low-Voltage applications. To find out the connections among several multilevel Voltage Source Converter (VSC) topologies and to expose in what way to attain innovative topologies. Between them, VSC attained the main market share and taken obvious improvements in the earlier time. The most topical developments in the VSCs is a Modular Multi-level Converter (M-MC). This configuration has a modular structure; power rating and voltage of the converter can be enlarged by accumulating the Sub-Modules (SM) in series. This paper presents the VSC based M-MC of high power converters, which the controller controls the voltage on the load using a PI controller. The simulation results of converter voltage, converter current, grid voltage, grid current, PI error voltage, three-phase instantaneous real power, and reactive power obtained to justify the achievement of the suggested topology. © 2019 IEEE.
