Comparison of SVPWM and SPWM on PMSM Speed Control fed by PV Array with SEPIC MPPT

Abstract

In this paper, speed control of PMSM that is fed by PV array on the basis of vector control is realized. Besides, switching signals for PMSM are obtained by both SVPWM and SPWM and their effect on the speed is compared. Furthermore, MPPT consisting of PO method is applied by using SEPIC DC-DC converter. This study is carried out by using Matlab/Simulink. Also, the change of irradiation level and ambient temperature of PV array are included in the study. By simulations, PMSM speed under reference and load changes, PV array power are measured and compared.
