Abstract：This paper mainly develops a novel topology，which is called quasi-Z-source inverter（QZSI），derived from the traditional
Z-source inverter（ZSI）.The equivalent circuit and operating principle analysis are given and the space-vector PWM
technique is applied into single phase QZSI（spQZSI），the basic modulation principle and control strategy of spQZSI based
SVPWM are showed.The simulation and experimental results indicate the presented QZSI has merits of suppress the inrush
current and remarkable lower component voltage ratings，thus save the entirety costs and strength the system reliabilities.
