Space vector pulse-width modulation based maximum boost control of Z-source inverters

In this paper, a novel maximum boost control method is presented based on the space vector pulse-width modulation (SVPWM) technique for the three-phase Z-source inverter (ZSI). Compared with the traditional carrier-based maximum boost control strategy, the proposed method has a wider linear operation range and is easier for digital implementation. What's more, the number of switching transition in each switching cycle is reduced, which indicates less switching power losses. It will be beneficial for the further industrial applications of the ZSIs. The simulation results in Matlab/Simulink as well as comparative performance have been provided and discussed, which have validated all theoretical analysis in the paper.
