New Simplified Space Vector Modulation for Three Phase Asymmetric Multilevel Inverter with Reduced Switch Count Using One Dimensional Modulator

Abstract

The Space Vector Modulation [SVM] technique which is primarily utilized in phase-3 inverters because it delivers greater utilization source, operation based on linear performance and Total Harmonic Distortion (THD). If the inverter supposes to be greater amount of level or greater quantity of phases, the control region representation has become entirely complex also the strategies of SVM has to consider greater amount of switching states. To overcome this simple one-dimensional modulator for a three phase Seven Level Asymmetric Multilevel Inverter (SLAMLI) with reduced components is proposed at present work. The suggested one-dimensional strategy is employed to modulate every stage of the SLAMLI separately, whereas traditional SVM techniques consider the converter as a whole system. The suggested methodology has the benefit of being able to have any topology and any level of authority without providing new complexity. Also, it naturally suppresses the magnitude of Common Mode Voltage (CMV) and keeps it constant without any post processing. This reduced CMV benefits negligible leakage current. Consequently, MATLAB/SIMULINK has to done by means of evaluate the sustainability of the suggested technique.
