Comparison of SVPWM and SVM controlled smart VSI fed PMSG for wind power generation system

Abstract

SVPWM and SVM controlled smart VSI fed PMSG consisting of three phase diode bridge rectifier and three phase IGBT bridge inverter is proposed in the paper. SVM control strategy is used to control the inverter voltage. The ripple free output waveform is provided by SVPWM and so it is most desired. In the conventional method they SVPWM is used to control the inverter. For the same system SVM controlled VSI is applied and the THD level is analysed. It is found to be less when compared to SPWM control method. The comparison of both conventional as well as proposed model was verified and analysed using MATLAB simulation and 800W experimental setup.
