Comparative analysis of 3D‐SVM and 4D‐SVM for five ‐phase voltage source inverter

Abstract

Pulse width modulation (PWM) methods play a major role to control the various power electronic converters to progress the recital of the system. In this paper, a comparative analysis is done for three dimensional space vector modulation (3D-SVM) and four dimensional space vector modulation (4D-SVM) for five-phase voltage source inverter. 3D-SVM method comprises all qualities of conventional SVM; switching time calculation is simple and much suitable for three-phase system; where in five-phase system, it has redundant switching state vectors. 4D-SVM includes advantages of 3D-SVM and other conventional methods, it employs only nonredundant switching state vectors; it directs to diminish the intricacy in switching time calculations and avoids trigonometric calculations and look up tables for reference vector identification. The various parameters such as total harmonic distortion, improved output voltage, minimized common mode voltage and switching time calculation are analyzed and compared for 3D-SVM and 4D-SVM techniques. Simulation and hardware results are acquired and established using matlab simulink and FPGA processor, respectively.
