Design and simulation a three-phase inverter by the space vector pulse width modulation control method with the approach of reducing the output voltage total harmonic distortion

Nowadays power quality is one of the most important aspects of power electronics engineering. In this article it is tried to reduce the power losses in power transmission in the presented three-phase inverter from the AC main to the load side with the space vector pulse width modulation method of switching the three-phase inverter in the controlling circuit unit. This article presents a three-phase inverter with a switching frequency of ۱۰ KHZ. This three-phase inverter is controlled by the space vector pulse width modulation method of switching the power electronic switches of this inverter. This switching method of the inverter is helpful due to the reducing of the output voltage third total harmonic distortion. After the output voltage's third total harmonic distortion is reduced, we have a better output voltage waveform with lower third harmonic and higher power factor and a better power quality of the output signal; as a result, a better power transmission from the DC side of the inverter to the AC side and the least power losses is seen by using this controlling method.
