Abstract

This study specially focused on Railway Electrical-Multiple-Units (E-M-Us) and demonstrate the implementation of 9-level Asymmetric-Cascaded H-bridge (AC-H-B) Multilevel Inverter (MLI) controlled with Fuzzy-Logic-Controller (F-L-C) in order to boost the class of output waveforms with the elimination of major harmonic contents in the output result. As the operation of railway EMUs system needs higher power as well as voltage. Thus it is an excellent choice to utilize Asymmetric Multi-level Inverter instead of Classical Inverter. An Asymmetric MLI which is controlled here utilizes 2-H-bridge modal with un-equal D-C supplies and it can be able to make multi-level sinusoidal waveform at the output for 3-phase Inductor Motor. Various parameters of motor with different loading condition have been studied. Here an Asymmetric MLI utilizes limited semi-conductor IGBT switches and D-C voltage supply. Therefore financial spending and size of the railway EMU system will be compressed. So as efficiency of system will improve. Prototypical Simulation has been performed by MATLAB/simulink software in order to verify the operation of an Asymmetric MLI based EMU system.
