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
