Matrix converters and three-phase inverters fed linear induction motor drives—Performance compare

AbstractIn this paper, the system of the Linear Induction Motor (LIM) driven by direct AC–AC matrix converter is presented and its dynamic performance is briefly compared with the conventional LIM drives based on AC–DC–AC converter. Space-vector pulse-width modulation (SVM) and indirect field oriented control (IFOC) are applied to control the two employed converters. For the sake of comparison, the PI controllers are applied to control the primary (mover) speed and current considering the same parameter settings. The objective of this paper was to compare theoretically the dynamic performance of linear induction motor (single-sided LIM) drives driven by three-phase voltage source inverters and the direct AC/AC matrix converters. The study compares the dynamic performance in addition to the harmonics content and THD of the input and output voltage and current for both converters. The simulation of each system has been implemented using the MATLAB/SIMULINK platform
