This study proposes a new control strategy for the quasi Z-source two-level three-phase inverter, accurate discontinuous SVM (AD-ZSVPWM). The proposed AD-ZSVPWM control technique enhances the output power quality by reducing total harmonic distortion (THD) and conduction losses. Low THD is achieved by increasing the algorithm's accuracy using a division of six vector states in each switching period and the distribution of six shoot-through states within the period. The conduction losses are reduced by splitting each sector into two subsectors of 30 degrees. The proposed control scheme has the following advantages: reduced THD, low conduction loss, and increased boosting factor. MATLAB/Simulink software is used, and an experimental test is conducted to validate the proposed strategy. PLECS software is utilized to calculate the switching and conduction losses. For experimental verification, a hardware test bench comprising a dSPACE DS1104 board that controls a three-phase quasi Z-source inverter that supplies an R-L load is used. Simulation and hardware results show that the proposed scheme provides improved performance in terms of power quality and power loss reduction.
