Abstract For the special requirements of grid-connected inverter used in wind power generation system a
kind of three-phase Z-Source inverter operational principle is analyzed in this paper. Formulas for the design of
main parameters under the control of constant duty cycle of shoot-through switching state are derived. Then the sim-
ulation models of SVPWM with shoot-through zero vectors are built by Matlab /Simulink in order to control the
switch of Z-Source inverter on and off. The independent control strategy of d-axis and q-axis currents is used to
achieve a unity power factor grid-connected aim. Simulation results show that the theoretical analysis and the simu-
