Simulation and Analysis of Conventional and Non-Conventional Three Phase Five Level Multilevel Current Source Inverters

摘要

This paper presents a study and analysis of conventional and non-conventional 5-level multilevel current source inverters. To facilitate for a convergence, the angle control method for harmonic control has been applied to all the circuits in accordance with an appropriate switching table. The single phase circuits are implemented in a MATLAB/SIMULINK environment, the multilevel current waveform through the resistive load has been observed (same for all) and the total harmonic distortion recorded. Based on simulation results a comparison is proposed at the end comparing the number of switches, number of inductors required and the total harmonic distortion resulting that the a particular non-conventional topology is more feasible for a three phase actual hardware implementation.
